Semen quality pattern and age threshold: a retrospective cross-sectional study of 71,623 infertile men in China, between 2011 and 2017.

ABSTRACT:

Background

The aim of this study was to provide information on the semen quality pattern of infertile men and age thresholds for semen parameters in China.

Methods

This was a retrospective cross-sectional study investigating 71,623 infertile men from the Reproductive and Genetic Hospital of CITIC Xiangya in Hunan, China, from 2011 to 2017. The Kruskal-Wallis test, Mann-Kendall test, linear regression model and joinpoint regression were used.

Results

Although erratic changes were observed in the median semen parameters (sperm concentration 40.1-52.1 × 10⁶/ml, total sperm count 117.8-153.1 × 10⁶, sperm progressive motility 33.4-38.1%) during the 7 years of observation, no significant decrease in semen quality was found, and 47.88% of infertile men
