Time to improvement in semen parameters after microsurgical varicocelectomy in men with severe oligospermia

We aimed to determine the time and predictive factors of semen quality improvement in men with severe oligospermia after microsurgical varicocelectomy. Methods: Men with total motile sperm count (TMSC) 6 months. We evaluated preoperative factors for successful semen quality upgrading based on assisted reproductive technology (ART) eligibility: in vitro fertilization [IVF] ( 9 million). We compared men with TMSC 6 months postoperatively. Results: A total of 33 men were included. TMSC improved from 1.5±0.2 to 7.3±1.8 million at 3–6 months (p 6 months (p 6 months. Sixteen (48.5%) men upgraded semen quality into the range of natural pregnancy. Preoperative TMSC from 2–5 million was predictive of upgrading semen quality. Twenty-four couples were contacted by phone; 20 were attempting pregnancy in the postoperative period and five (25%) of them had achieved natural pregnancy. Conclusions: Men with TMSC 2 million was most predictive of semen quality upgrading.
