- Abstract
Background: There are many studies showing that more days of sexual abstinence increased sperm concentration, however, the direct influence between the days of abstinence and pregnancy rates has not been evaluated. The usual recommendation is 3-4 days prior to intrauterine insemination; this based on the interval that maximizes the number of motile sperm in the ejaculate. There are some reports with better success rate when abstinence is less than three days. Objective: To evaluate the pregnancy rate post-intrauterine insemination according to days of sexual abstinence prior to obtaining semen sample. Patients and methods: A retrospective, observational and transversal study in patients attending the Mexican Center for Fertility (CEPAM) to intrauterine insemination. For analysis patients were grouped by age group, success rate and days of sexual abstinence. Continuous variables are reported as means and standard deviations; to determine statistical significance univariate logistic regression was performed. Categorical variables were evaluated in frequencies and percentages. The calculations were performed using JMP software program. Results: 3,123 couples were included and increased success rate for intrauterine insemination was obtained with less than seven days of sexual abstinence. The rate of sperm retrieval is inversely proportional to the days of abstinence. Conclusion: A better pregnancy rate in intrauterine insemination was achieved with less than seven days of sexual abstinence and sperm retrieval rate was also recorded with fewer days of abstinence.
