Taipei, Feb. 5 (CNA) The quality and quantity of semen sampled from sperm donors in
Taiwan have deteriorated in recent years, a recent study by the Center for Reproductive Medicine and Sciences (CRMS) of Taipei Medical University found.
In the study, researchers found that there has been an annual decline of sperm concentration in every cubic centimeter of semen collected from donors.
According to CRMS Director Tseng Chi-jui (曾啟瑞), a healthy male can typically produce 3 to 5 cubic centimeters (c.c.) of semen in every orgasm, with each c.c. containing 60 million sperms, or 300 million in total.
“Every year we would see a roughly one percent drop, or about 600,000 sperms, in the samples,” Tseng said. [FULL STORY]
