Abstract

Abstract:

Objective To investigate the reference interval of semen parameters from sperm donors in Zhejiang,and to provide a reference for fertility evaluation of clinical patients. Methods Semen samples from4 122 sperm donors at Zhejiang Human Sperm Bank were collected from Januray 2017 to August 2019. Routine semen analysis and semen morphology analysis were performed according to the World Health Organization（WHO） the 5th-edition guidelines,and the pH value,volume,sperm concentration,total sperm count,sperm progressive motility and the rate of sperm normal morphology were determined. The reference interval of semen parameters was obtained,which was compared with that of WHO the 5th-edition guidelines. Results The reference intervals of semen parameters were as follows,volume≥1.8 mL,total sperm count ≥51×10⁶/time,sperm concentration ≥16×10⁶/mL,PR≥20%,the rate of sperm normal morphology≥5% and the pH value≥8.0. Conclusions Compared with the reference interval of WHO the 5th-edition guidelines,Zhejiang sperm donors has low PR,and the reference intervals of the other semen parameters were different. The numerical distribution of semen parameters in Zhejiang is slightly different from that of WHO the 5th-edition guidelines,especially in the high percentile above P₅₀. With the increase of sperm donors,especially for males over 40 years old,sperm quality decreases significantly.
