Aim: This study aims to find out how different sexual abstinence period influences semen parameters, fertilization, embryo development, and pregnancy rates in patients undergoing conventional in vitro fertilization. Setting and designs: A retrospective analysis was conducted at a tertiary level infertility care clinic. Materials and methods: The clinical study included 532 patients between January 2017 and July 2021 who had been treated with conventional in vitro fertilization. The effect of sexual abstinence on primary outcomes such as semen volume, total sperm concentration, total motile sperm concentration, sperm morphology, and secondary outcomes such as fertilization rate, cleavage rate, top quality day 3 and day 5 embryo development rate, implantation and clinical pregnancy rate between fresh versus frozen embryo transfer on day 3 and day 5 of conventional in vitro fertilization under three groups, that is, sexual abstinence of less than or equal to 1, 2 to 5, and 6 to 7 days was evaluated. Statistical analysis used: Chi-square test was used to evaluate the qualitative variables whereas one-way analysis of variance was used to evaluate the quantitative variables. Results: Group II with 2 to 5 days of abstinence, observed a positive correlation between abstinence period and semen volume, total sperm concentration, total motile sperm concentration, and morphology. Fertilization rate was higher in groups II and III than group I (P = 0.21) with no significant difference in cleavage rate (P = 0.4) and embryo development on day 3 (P = 0.1057). The formation of AA grade blastocyst between group I and group II was 27.54 % and 23.47 %, respectively, with a P-value of 0.007154. Both fresh and frozen embryo transfers of groups II and III of abstinence period had implantation and clinical pregnancy rates of 23.39% and 43.83%, respectively. Conclusion: Our study did not find any significant difference in primary and secondary outcomes of conventional in vitro fertilization between the three groups. We recommend further prospective large randomized control studies to prove any association between duration of abstinence and pregnancy outcomes.
