The relationship between male reproductive function and the blood plasma level of epidermal growth factor (EGF) is of interest in the light of the role that circulating EGF appears to play in regulating mouse spermatogenesis. We measured the concentrations of EGF in the blood plasma of 39 fertile men (sperm count > 20 x 10(6)/ml) and compared them with those of 31 infertile men (sperm < 20 x 10(6)/ml). Blood plasma levels of follicle stimulating hormone (FSH), luiteinising hormone (LH), prolactin and testosterone were also determined. The infertile patients had mean blood plasma EGF concentrations of 0.75 +/- 0.10 ug/L. The value was significantly lower than that of the fertile group (1.28 +/- 0.14 ug/L; P < 0.005). There were statistically significant differences between the fertile and infertile groups in sperm count, sperm viability, mean forward progression, testosterone, LH and FSH (P values between 0.0001 and 0.023). There was no significant difference in the prolactin concentrations between the two groups. Although overall average blood plasma EGF concentrations are significantly lower in the infertile males, regression analysis failed to reveal any direct relationships among the various parameters studied.
