Introduction: Infertility is a global public health problem; cost-effective patient-friendly treatment modalities along with psychosexual intervention strategies are essential for infertility control/prevention/management among ethnically disparate populations. Objectives: This study aimed to assess differential in vitro fertilization (IVF) success trends among infertile women of South Indian ethnicity. Materials and Methods: Prospective, observational study designed in a hospital-based setting with active enrollment of infertile women undergoing IVF/intracytoplasmic sperm injection (ICSI) at Indira IVF Center, Chennai, Tamil Nadu, India (April-September 2019); inclusion criteria: age >35 years, South Indian ethnicity, married >1 year, absence of full-term clinical pregnancy, endometrial thickness <6 mm/thin endometrium; exclusion criteria: prior ≥2 IVF failures, fibroids/adenomyosis/cervical cancer/endometriosis. IVF success was determined by evaluating total frozen embryos transferred/month, average oocyte yield/donor, oocyte quality, M-II oocytes, biochemical/clinical pregnancy (beta-human chorionic gonadotropin positivity/fetal cardiac activity). Mycobacterium tuberculosis positivity was assessed by GeneXpert polymerase chain reaction-based technology, and psychosexual intervention-incorporated marital relationship counseling sessions/therapy, referrals for psychiatric assessments (cognitive impairment/schizophrenia/depression). Written informed consent of participants was taken and study was approved by Institutional Review Board. Results: Mean age and endometrial thickness of study participants were 33.3 years (SD ±1.9) and 8.7 mm (SD ±0.5), respectively; average Body Mass Index (BMI) and anti-müllerian hormone (AMH) levels were 28.4 kg/m2 and 4.7 ng/mL, respectively. Embryos transferred/month: 7 in April/13 in May/24 in June/36 in July/24 in August/30 in September, and pregnancies: 4/8/17/26/20/22 for the months of April, May, June, July, August, and September 2019, respectively. Subgroup stratification demonstrated M-II vs total oocytes retrieved were 76%, 73%, 60%, 71%, 77%, and 77%. Overall IVF success rates were 57% in April/62% in May/71% in June/72% in July/83% in August/73% in September; frozen embryo transfer success was 0 in April-May/67% in June/73% in July/89% in August/100% in September 2019. English/Tamil-speaking infertile women self-reported treatment-related satisfaction rates of 80% to 100%. Conclusion: M-II oocytes’ yield, sociodemographics of infertile women, and increasing age/aberrant AMH/BMI profiles/endometrial receptivity/diminished ovarian reserve are promising predictors of IVF/ICSI success in genetically distinct patient population subset(s). Future multicentric gene epidemiology studies with larger sample size and precision-based psychiatric assessments/interventions are warranted for development of predictive biomarkers in infertility management.
