Despite sizable number of women suffering from infertility, empirical evidence on the relation between infertility and KOC is rare in South Asia. This study assesses the association between primary infertility and KOC. The data of ever-married women aged 20-49 gathered in the recent rounds of Demographic and Health Survey (DHS) for India (2019-2021), Bangladesh (2017-2018), Pakistan (2017-2018) and Nepal (2022) were analyzed. Bivariate analysis and binary logistic regression were conducted through Stata (V.17) with a 5% significance level. Women with no KOC in India [AOR:1.71, C.I.: (1.54, 1.9)] and Bangladesh [AOR:2.6, C.I.: (1.67, 4.06)] had higher odds of primary infertility than their counterparts with correct KOC. The study concludes that correct KOC is a significant predictor of primary infertility in India and Bangladesh and is insignificant in Pakistan and Nepal. Moreover, higher age at marriage and no-visit to healthcare facility were the other significant predictors of primary infertility in all four countries. Women who are struggling to conceive would benefit from education related to the timing and identification of the fertile window, which may be provided through primary healthcare providers.</p>","PeriodicalId":13006,"journal":{"name":"Human Fertility","volume":"28 1","pages":"2441832"},"PeriodicalIF":2.1,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142863741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent data have suggested that sufficient D3 levels are associated with improved outcomes of <i>in vitro</i> fertilization (IVF), although other studies failed to confirm so. Screening for D3 levels before IVF is becoming common practice in many IVF centres, and D3 insufficiency is treated with supplements before treatment. However, little is known about the effect of this intervention on D3 levels during endometrial preparation for frozen-embryo transfer (FET) cycles, especially regarding clinical outcomes. To examine the effect of vitamin D supplementation and the impact of vitamin D status in women undergoing FET cycles, a prospective study of infertile women undergoing FET cycles was carried out. Initial screening of D3 levels was performed in 252 infertile women before a FET cycle, and where insufficiency was found (<30 ng/mL) [115 (45.6%)], supplements were prescribed according to a standardized protocol. Serum D3 levels were measured at three distinct time-points: at the initiation of endometrial preparation (T1), embryo transfer (T2), and beta-hCG testing (T3). We found no significant difference in ongoing pregnancy [40 (34.8%) <i>vs.</i> 51 (37.2%); odds ratio (OR) 0.90, 95% confidence interval (CI) 0.54-1.51; adjusted OR 1.04, 95% CI 0.58-1.83], live birth, positive β-hCG, clinical pregnancy, miscarriage, and ectopic pregnancy rates between D3-insufficient participants at T1 receiving vitamin D and D3-replete ones not receiving any supplementation (<i>p</i>-values >0.05).

In conclusion, this prospective cohort study of women undergoing FET cycles found no significant difference in ongoing pregnancy rates between D3-insufficient participants receiving supplementation at the beginning of endometrial preparation and replete ones receiving no supplementation.
