The Use of Pooled Consecutive Ejaculates in Moderate Male Factor Infertility to Increase Intrauterine Insemination Success.

Background: Male factor is a predominant cause of infertility. Success rates of intrauterine insemination(IUI) for male factor depend upon minimum semen parameters such as progressive motility > 30%, strict morphology > 4%, total motile count in the native sample (TMSC) >5 million and inseminating motile count (IMC) > 5 million. Couples with parameters lesser than these are usually advised IVF-ICSI. In developing countries, affordability for IVF is an important deterrent to its widespread utilisation. Aims: To evaluate pregnancy rates after the use of a pooled consecutive ejaculate in infertile men with semen parameters of 5 million TMSC after processing of a single ejaculate. Settings and Design: Private infertility practice. Retrospective study from Oct 2012 to June 2019. Methods and Materials: All consecutive patients (n=1979) who underwent IUI in the given study period were included. Patients undergoing donor sperm insemination and low IMC (
