Table 3 Epididymal and testicular sperm parameters from control and MSG groups

From: Glutamate-induced obesity leads to decreased sperm reserves and acceleration of transit time in the epididymis of adult male rats

Groups Control (n = 9) MSG (n = 9)
Daily sperm production (x 106/testis/day) 43.13 ± 1.62 21.90 ± 1.24*
