REVIEW ARTICLES
Female genital tuberculosis: Revisited
Jai Bhagwan Sharma, Eshani Sharma, Sangeeta Sharma, Sona Dharmendra
December 2018, 148(7):71-83
DOI:10.4103/ijmr.IJMR_648_18  PMID:30964083
Female genital tuberculosis (FGTB) is caused by Mycobacterium tuberculosis (rarely Mycobacterium bovis and/or atypical mycobacteria) being usually secondary to TB of the lungs or other organs with infection reaching through haematogenous, lymphatic route or direct spread from abdominal TB. In FGTB, fallopian tubes are affected in 90 per cent women, whereas uterine endometrium is affected in 70 per cent and ovaries in about 25 per cent women. It causes menstrual dysfunction and infertility through the damage of genital organs. Some cases may be asymptomatic. Diagnosis is often made from proper history taking, meticulous clinical examination and judicious use of investigations, especially endometrial aspirate (or biopsy) and endoscopy. Treatment is through multi-drug antitubercular treatment for adequate time period (rifampicin, isoniazid, pyrazinamide, ethambutol daily for 60 days followed by rifampicin, isoniazid, ethambutol daily for 120 days). Treatment is given for 18-24 months using the second-line drugs for drug-resistant (DR) cases. With the advent of increased access to rapid diagnostics and newer drugs, the management protocol is moving towards achieving universal drug sensitivity testing and treatment with injection-free regimens containing newer drugs, especially for new and previously treated DR cases.

Family planning in India: The way forward
Poonam Muttreja, Sanghamitra Singh
December 2018, 148(7):1-9
DOI:10.4103/ijmr.IJMR_2067_17  PMID:30964076
Given the magnitude of the family planning programme in India, there is a need to strengthen the coordination of all its aspects, focusing on planning, programmes, monitoring, training and procurement. The quality of care in family planning must be a major focus area to ensure the success of family planning programmes. Despite serious efforts and progress, India has yet to achieve its family planning goals. Furthermore, there is a need for greater male participation both as enablers and beneficiaries and also address the sexual and reproductive needs of the youth. It is imperative for the government to ensure the prioritization of family planning in the national development agenda. Family planning is crucial for the achievement of the sustainable development goals, and subsequent efforts need to be made to improve access and strengthen quality of family planning services.

Infertility & assisted reproduction: A historical & modern scientific perspective
Radhey Shyam Sharma, Richa Saxena, Rajeev Singh
December 2018, 148(7):10-14
DOI:10.4103/ijmr.IJMR_636_18  PMID:30964077
Infertility has always been considered as a social stigma and has often been treated as socially, mentally and physically damaging experience for the childless women rather than man. Fatherhood was more a social rather than biological concept, thereby making childlessness a legitimate ground for divorce and a matter of disgrace for women. Every country has its own set of customs and traditional beliefs for the relief of childlessness. While introducing a second wife was one way to overcome the predicament of childlessness, divorce was also an available choice. There were several myths that contemplated the human concerns and their needs during ancient times. It is evident that types of the infertility and their treatment in the modern era have some historical background and different representations in the ancient civilizations. The present review discusses the historical and modern perspectives of infertility and assisted reproduction and their importance in different cultures.

Mid-life fertility: Challenges & policy planning
Umesh N Jindal
December 2018, 148(7):15-26
DOI:10.4103/ijmr.IJMR_647_18  PMID:30964078
This review highlights the challenges, priority areas of research and planning, strategies for regulation of services and the need to develop guidelines and laws for fertility treatments during mid-life. The success rate of all treatments is poor in advanced age women because of declining ovarian reserve and natural fertility. There is often a need of third-party involvement which has its own ethical, legal and medical issues. Welfare of children born to older women and early death of parents are important concerns. Most of the new techniques such as the pre-implantation genetic diagnosis, oocyte augmentation, use of stem cells or artificial gametes, ovarian tissue preservation and ovarian transplantation are directed to improve, preserve or replace the declining ovarian reserve. These techniques are costly and have limited availability, safety and efficacy data. Continued research and policies are required to keep pace with these techniques. The other important issues include the patients' personal autonomy and right of self-determination, welfare of offspring, public vs. private funding for research and development of new technologies vs. indiscriminate use of unproven technology. It is important that mid-life fertility is recognized as a distinct area of human reproduction requiring special considerations.

Effect of radiofrequency radiation on reproductive health
Rajeev Singh, Ravindra Nath, Ajit Kumar Mathur, Radhey Shyam Sharma
December 2018, 148(7):92-99
DOI:10.4103/ijmr.IJMR_1056_18  PMID:30964085
The development of cellular phone system has greatly increased the extent and magnitude of radiofrequency radiation (RFR) exposure. The RFR emitted from mobile phone and mobile phone base stations exerts thermal and non-thermal effects. The short-term and long-term exposure to RFR may have adverse effect on humans as well as animals. Most laboratory studies have indicated a direct link between exposure to RFR and adverse biological effects. Several in vitro studies have reported that RFR induces various types of cancer and DNA or chromosomal damage. On the other hand, some animal studies have not reported adverse effects of this radiation. The present review summarizes information available on the possible effects of RFR on the reproductive health.

Stem cells survive oncotherapy & can regenerate non-functional gonads: A paradigm shift for oncofertility
Deepa Bhartiya
December 2018, 148(7):38-49
DOI:10.4103/ijmr.IJMR_2065_17  PMID:30964080
A large proportion of patients who survive cancer are rendered infertile as an unwanted side effect of oncotherapy. Currently accepted approaches for fertility preservation involve banking eggs/sperm/embryos or ovarian/testicular tissue before oncotherapy for future use. Such approaches are invasive, expensive, technically challenging and depend on assisted reproductive technologies (ART). Establishing a gonadal tissue bank (for cancer patients) is also fraught with ethical, legal and safety issues. Most importantly, patients who find it difficult to meet expenses towards cancer treatment will find it difficult to meet expenses towards gonadal tissue banking and ART to achieve parenthood later on. In this review an alternative strategy to regenerate non-functional gonads in cancer survivors by targeting endogenous stem cells that survive oncotherapy is discussed. A novel population of pluripotent stem cells termed very small embryonic-like stem cells (VSELs), developmentally equivalent to late migratory primordial germ cells, exists in adult gonads and survives oncotherapy due to their quiescent nature. However, the stem-cell niche gets compromised by oncotherapy. Transplanting niche cells (Sertoli or mesenchymal cells) can regenerate the non-functional gonads. This approach is safe, has resulted in the birth of fertile offspring in mice and could restore gonadal function early in life to support proper growth and later serve as a source of gametes. This newly emerging understanding on stem cells biology can obviate the need to bank gonadal tissue and fertility may also be restored in existing cancer survivors who were earlier deprived of gonadal tissue banking before oncotherapy.

Natural products in regulation of male fertility
Raghav Kumar Mishra, Shilpi Singh, Shio Kumar Singh
December 2018, 148(7):107-114
DOI:10.4103/ijmr.IJMR_1968_17  PMID:30964087
Medicinal plants may prove useful in developing plant-based strategies for regulation of male fertility. The present review describes the antifertility potential of certain medicinal plants, viz. Azadirachta indica, Curcuma longa, Allamanda cathartica and Bacopa monnieri in Parkes (P) male mice. The results suggested that treatment with the aqueous extracts of these plants caused reversible suppression of spermatogenesis and fertility in P mice and that there were no signs of detectable toxicity in treated mice. Further research needs to be done to develop plant-based strategies for control of male fertility.

Naresh L Selokar
December 2018, 148(7):120-124
DOI:10.4103/ijmr.IJMR_2103_17  PMID:30964089
The term animal cloning refers to an asexual mean of reproduction to produce genetically identical copies of any animal without the use of sperm. In India, the cloning of buffalo is well established and clones of the Murrah, the best dairy breed of buffalo, have been produced. The most acclaimed example is the restoration of progeny-tested breeding bull by isolating somatic cells from frozen doses of semen, which were stored for more than a decade in the semen bank. Buffalo bull cloning is considered the best available option to reproduce declared proven bulls and their semen would contribute to accomplishing the demand of ever-growing frozen semen, which is the prime requirement of conventional breeding. This article highlights the importance of buffalo bull cloning and its current status in India.

Meditation & yoga: Impact on oxidative DNA damage & dysregulated sperm transcripts in male partners of couples with recurrent pregnancy loss
Vidhu Dhawan, Manoj Kumar, Dipika Deka, Neena Malhotra, Vatsla Dadhwal, Neeta Singh, Rima Dada
December 2018, 148(7):134-139
DOI:10.4103/ijmr.IJMR_1988_17  PMID:30964091
Background & objectives: Recurrent pregnancy loss (RPL) is one of the devastating complications of pregnancy and current focus lies in addressing the management of paternal factors. Dysregulation in selective transcripts delivered to oocyte at fertilization can result in pregnancy losses and adversely affect embryogenesis. The objective of this study was to assess the effect of yoga-based lifestyle intervention (YBLI) on seminal oxidative stress (OS), DNA damage and spermatozoal transcript levels. Methods: The present study was a part of a prospective ongoing exploratory study and 30 male partners of couples with RPL were included from August 2016 to June 2017. Semen samples were obtained at baseline and at the end of YBLI (21 days). Gene expression analysis was performed by quantitative polymerase chain reaction on spermatozoal FOXG1, SOX3, OGG1, PARP1, RPS6, RBM9, RPS17 and RPL29. The levels of seminal OS and sperm DNA damage was assessed by measuring levels of reactive oxygen species (ROS) by chemiluminescence and DNA fragmentation index (DFI) by sperm chromatin structure assay. Results: SOX3, OGG1 and PARP1 were observed to be upregulated, while FOXG1, RPS6, RBM9, RPS17 and RPL29 showed downregulation. A significant reduction in ROS levels, an increase in sperm motility, sperm count (done twice) and a decrease in DFI was seen after YBLI. Interpretation & conclusions: Adopting YBLI may help in a significant decline in oxidative DNA damage and normalization of sperm transcript levels. This may not only improve pregnancy outcomes but also improve the health trajectory of the offspring.

Socio-economic correlates of bereavement among women - Examining the differentials on social axes
Sanghmitra S Acharya
December 2018, 148(7):27-37
DOI:10.4103/ijmr.IJMR_779_18  PMID:30964079
Death, disease and disaster can inflict anyone, anywhere and at any time. While occurrence of such an event could be absolved of any selective strike, the outcome reflects otherwise. Historical deprivations experienced by certain populations have caused more bereavement and sorrow to them than those who have experienced lesser or no deprivation. Therefore, the process which shapes the factors to yield such a result is important and needs to be understood for any policy suggestions and programmatic inputs. Loss of pregnancy and newborn inflicts sorrow and bereavement across space, time and social labyrinth. The degree of bereavement is likely to reduce with time, but space and social context govern the response to it. Therefore, factors contributing to the differentials vary in their demographic, social and economic characteristics. The loss of pregnancy and newborn remains inadequately addressed. Family and community play a significant role in coping. While the developed countries have institutional structure to address coping with the loss, the South Asian countries rely heavily on the family and the community for such support. The present review examines these trajectories across social groups.

Arpit Bhargava, Rupesh Kumar Srivastava, Dinesh Kumar Mishra, Rajnarayan R Tiwari, Radhey Shyam Sharma, Pradyumna Kumar Mishra
December 2018, 148(7):50-63
DOI:10.4103/ijmr.IJMR_224_18  PMID:30964081
Female reproductive tract cancers (FRCs) are considered as one of the most frequently occurring malignancies and a foremost cause of death among women. The late-stage diagnosis and limited clinical effectiveness of currently available mainstay therapies, primarily due to the developed drug resistance properties of tumour cells, further increase disease severity. In the past decade, dendritic cell (DC)-based immunotherapy has shown remarkable success and appeared as a feasible therapeutic alternative to treat several malignancies, including FRCs. Importantly, the clinical efficacy of this therapy is shown to be restricted by the established immunosuppressive tumour microenvironment. However, combining nanoengineered approaches can significantly assist DCs to overcome this tumour-induced immune tolerance. The prolonged release of nanoencapsulated tumour antigens helps improve the ability of DC-based therapeutics to selectively target and remove residual tumour cells. Incorporation of surface ligands and co-adjuvants may further aid DC targeting (in vivo) to overcome the issues associated with the short DC lifespan, immunosuppression and imprecise uptake. We herein briefly discuss the necessity and progress of DC-based therapeutics in FRCs. The review also sheds lights on the future challenges to design and develop clinically effective nanoparticles-DC combinations that can induce efficient anti-tumour immune responses and prolong patients' survival.

Postpartum uterine infection & ovarian dysfunction
Sunita Dahiya, Suman Kumari, Payal Rani, Suneel Kumar Onteru, Dheer Singh
December 2018, 148(7):64-70
DOI:10.4103/ijmr.IJMR_961_18  PMID:30964082
Postpartum uterine infections such as metritis, endometritis and mastitis have been considered as underlying causes for ovarian dysfunction in mammals. Almost all mammals, particularly dairy animals are susceptible to postpartum uterine infections, resulting in impaired fertility and economic loss. One of the factors for low fertility in females is ovarian dysfunction, which is exhibited as impaired growth and function of ovarian follicles by the postpartum infection. Immune system of mammals provides a host defence mechanism against pathogenic microbes through the recognition of pathogen-associated molecular patterns (PAMPs) and forming inflammasomes. Like immune cells, ovarian granulosa cells also exhibit a similar pattern of cytokine gene expressions on exposure to PAMPs. Genome-wide transcriptomic approaches explored the molecular mechanisms underlying the immune function of buffalo granulosa cells during endotoxin exposure. Understanding the molecular mechanism of ovarian dysfunction due to uterine infection would be helpful to implement various strategies to handle the adverse effects of postpartum uterine disease on fertility by developing potential therapeutics. Therefore, this article focuses on key factors that are responsible for postpartum infection and particularly summarizes the molecular mechanism of infection underlying the ovarian dysfunction in dairy animals.

Sunil Kumar, Vineet Mishra, Riddhi Thaker, Mansi Gor, Siva Perumal, Pratiksha Joshi, Hardik Sheth, Idrish Shaikh, Anil K Gautam, Yogendra Verma
December 2018, 148(7):125-133
DOI:10.4103/ijmr.IJMR_1864_17  PMID:30964090
Background & objectives: Oxidative stress, lifestyle factors as also exposure to certain environmental factors are known to affect the fertility status in human beings. The aim of this study was to evaluate the role of OS and lifestyle and environmental factors affecting IVF outcome. Methods: A total of 253 couples were included, and biological samples such as blood, follicular fluid (FF), cumulus cells and semen were collected. Relevant biochemical parameters and metals namely lead (Pb), cadmium (Cd), copper (Cu) and zinc (Zn) were determined in the biological samples. β-human chorionic gonadotropin levels ≥100 IU/l were considered to predict viable pregnancy on the 15th day of embryo transfer (ET). Results: The mean body mass index (BMI) was significantly lower in females with positive IVF outcome compared to those with negative outcome. Couples residing in the residential area showed more percentage of positive IVF outcomes as compared to couples residing in industrial/agricultural area. FF Zn level was significantly higher (P<0.001) among the females' participants who have undergone ET as compared to those who have not undergone ET. FF MDA and serum Cu levels were significantly higher (P<0.05) in the female participants with negative IVF outcome as compared to positive IVF outcome. Logistic regression revealed that maternal BMI (P=0.034) and FF MDA level (P=0.047) were significantly associated with the IVF outcome. Interpretation & conclusions: The success rate of IVF was about 31.8 per cent, and BMI was significantly lower in females with positive outcome. The higher levels of MDA in FF and SP might have a negative impact on IVF outcome, higher Zn level in SP, FF and serum might have a positive role in embryo transfer as well as IVF outcome. The role of stress management and nutrition supplementation during the IVF treatment may be explored.

Redox regulation & sperm function: A proteomic insight
Gayatri Mohanty, Luna Samanta
December 2018, 148(7):84-91
DOI:10.4103/ijmr.IJMR_242_18  PMID:30964084
Infertility affects nearly 15 per cent of all couples within the reproductive age worldwide, with about 50 per cent being exhibited in the male, called male factor infertility. Successful reproduction is dependent on sperm chromatin integrity. Spermatozoa are highly specialized cells that aim to transmit the paternal genomic blueprint to the oocyte. The spermatozoon is regulated by redox mechanisms during its epididymal transit to acquire fertilizing ability. While, at physiological levels, the production of reactive oxygen species (ROS) supports the spermatozoon to acquire its fertilizing ability, at high concentrations, it affects sperm function leading to infertility. Emerging proteomic technologies provide an opportunity to address these key issues that may solve many fertility-associated problems resulting from oxidative stress (OS). This review highlights the need for an efficient therapeutic approach to male infertility with the application of high-throughput OS-mediated proteomic technology, and also addresses the question as to whether targeting these altered sperm-specific proteins may help in designing an efficient and reversible male contraceptive.

Effect of six-month use of oral contraceptive pills on plasminogen activator inhibitor-1 & factor VIII among women with polycystic ovary syndrome: An observational pilot study
Syed Douhath Yousuf, Mohammad Ashraf Ganie, Samoon Jeelani, Syed Mudassar, Zaffar Amin Shah, Mohammad Afzal Zargar, Shajrul Amin, Imtiyaz Ahmad Wani, Fouzia Rashid
December 2018, 148(7):151-155
DOI:10.4103/ijmr.IJMR_1899_17  PMID:30964093
Background & objectives: Polycystic ovary syndrome (PCOS) is an endocrinopathy warranting lifelong individualized management by lifestyle and pharmacological agents mainly oral contraceptive pills (OCPs). This study was aimed to report the impact of six-month OCP use on plasminogen activator inhibitor-1 (PAI-1) and factor VIII (FVIII) in women with PCOS. Methods: PCOS women diagnosed on the basis of Rotterdam 2003 criteria, either treated with OCPs (ethinyl estradiol-0.03 mg, levonorgestrel-0.15 mg) for a period of six months (n=40) or drug-naïve (n=42), were enrolled in this study. Blood was drawn to estimate glucose, insulin levels and lipid profile. Chemiluminescence immunoassays were used to measure hormones (LH, FSH, PRL, T4). Plasma levels of PAI-I and FVIII were measured by commercially available kits. Results: Menstrual regularity, Ferriman-Gallwey score and serum total testosterone significantly improved in the OCP group compared to drug-naïve group (P<0.01). No significant difference was observed in PAI-1 levels of the two groups; however, significant decrease in FVIII levels was observed in OCP group as compared to drug-naïve group. PAI-1 levels of OCP group correlated positively with blood glucose two hours, triglycerides and insulin two hours, while FVIII levels of OCP group correlated negatively with fasting insulin and homoeostatic model assessment-insulin resistance. Interpretation & conclusions: OCPs use has differential effect on pro-coagulant markers among women with PCOS. Well-designed, long-term, prospective, large-scale studies are prerequisite to elucidate the efficacy and safety of OCP in the treatment of PCOS.

DOI:10.4103/ijmr.IJMR_2096_17  PMID:30964088
The reproductive cloning in buffalo in India has been started using a simplified somatic cell nuclear transfer technique named handmade cloning. Since the birth of first cloned female buffalo in 2009, a number of buffalo clones have been produced in India by utilizing different types of donor cells such as ear cells, embryonic stem cells, semen somatic cells and urine somatic cells. The use of buffalo cloning on a large scale is restricted due to low pregnancy rates and poor calf survival. Considerable attempts have been made to improve the overall buffalo cloning efficiency, particularly by modifying epigenetic reprogramming of cloned embryos. Previous studies have demonstrated that chemical epigenetic modifiers such as trichostatin A and 5-aza-2'-deoxycytidine, m-carboxycinnamic acid bishydroxamide can be used to treat donor somatic cells and reconstructed fused embryos to correct the epigenetic reprogramming to enhance the overall cloning efficiency in terms of live birth rates.

Effect of roscovitine on developmental competence of small follicle-derived buffalo oocytes
Sriti Pandey, Anjali Somal, Mehtab S Parmar, Swati Gupta, Mukesh K Bharti, Irfan A Bhat, B Indu, Vikash Chandra, G Sai Kumar, G Taru Sharma
December 2018, 148(7):140-150
DOI:10.4103/ijmr.IJMR_2068_17  PMID:30964092
Background & objectives: The lower recovery of competent oocytes in buffalo species limits the commercialization of in vitro embryo production technology in field condition. In this context, pre-maturation of small follicle (SF)-derived oocytes with meiotic inhibition may be a promising alternative to obtain more number of competent oocytes. Thus, the present study was conducted with an objective to enhance the developmental potential of less competent SF-derived buffalo oocytes. Methods: All the visible follicles (used for aspiration) from buffalo ovaries were divided into two categories: large follicle (LF) (follicles having diameter ≥6 mm) and SF (follicles of diameter <6 mm). The competence of LF and SF oocytes was observed in terms of brilliant cresyl blue (BCB) staining, cleavage rate, blastocyst rate and relative gene expression of oocyte and blastocyst competence markers. Thereafter, less competent SF oocytes were treated with 0, 12.5, 25, 50 and 100 mM doses of roscovitine (cyclin-dependent kinase inhibitor) to enhance their developmental potential. Results: Based on parameters studied, LF oocytes were found to be more competent than SF oocytes. Pre-maturation incubation of SF oocytes with roscovitine reversibly arrested oocyte maturation for 24 h to ensure the proper maturation of less competent oocytes. A significantly higher number of BCB-positive oocytes were noted in roscovitine-treated group than SF group. Cleavage and blastocyst rates were also higher in roscovitine-treated group. The relative messenger RNA expression of oocyte (GDF9, BMP15, GREM1, EGFR, PTGS2 and HAS2) as well as blastocyst (INF-τ, GLUT1 and POU5F1) competence markers was significantly greater in roscovitine-treated group relative to SF group. Again, on comparison with LF group, these parameters depicted a lower value in the treatment group. Interpretation & conclusions: The findings of this study has revealed that pre-maturation incubation of SF-derived oocytes with 25 μM roscovitine can improve its developmental competence and thus can be utilized to get maximum number of competent oocytes for better commercialization of in vitro embryo production technology in buffalo.

S100 proteins: An emerging cynosure in pregnancy & adverse reproductive outcome
Rachna Verma, Priyanka Verma, Snehil Budhwar, Kiran Singh
December 2018, 148(7):100-106
DOI:10.4103/ijmr.IJMR_494_18  PMID:30964086
S100 proteins are calcium (Ca2+)-binding proteins and these have an important function in progression, manifestation and therapeutic aspects of various inflammatory, metabolic and neurodegenerative disorders. Based on their involvement in intracellular or extracellular regulatory effects, S100 proteins are classified into three subgroups: one subgroup is specialized in exerting only intracellular effects, other performs both intracellular and extracellular functions and the third subgroup members only display extracellular regulatory effects. S100 proteins are expressed particularly in vertebrates and have cell-specific expression. Functionally, S100 proteins act through their surface receptors and regulate cell functions in autocrine or paracrine mode. Receptor for advanced glycation end products (RAGEs) and toll-like receptor 4 are the main surface receptors. S100 proteins participate in the regulation of cellular differentiation, proliferation, apoptosis and inflammation along with Ca2+ homeostasis, energy metabolism and cellular migration, and perform the respective functions through their interaction with transcription factors, nucleic acids, enzymes, receptors, cytoskeleton system, etc. Currently, their role in adverse pregnancy outcomes and compromised reproductive health is being explored. These proteins are present in amniotic fluid, endometrium tissue and foetal brain; therefore, it is quite likely that alterations in the expression levels of S100 family members will be affecting the particular function they are involved in and ultimately affecting the pregnancy in adverse manner. The current review discusses about an association of S100 proteins in pregnancy disorders such as endometriosis, intrauterine growth retardation and miscarriage.
