Abstract:
The aim of this study was to examine the relationship of semen parameters, sexual function-related hormones and waist/hip ratio. Eighty-one selected patients presenting with infertility were examined. Weight, height, waist circumference and hip circumference were measured, and reproduction-related hormone levels were determined. Semen was analysed by conventional methods. Semen volume, sperm concentration, motility, total sperm count, total motile sperm cell number, rapid progressive motile sperm count and reproduction-related hormone levels [follicle-stimulating hormone, luteinizing hormone, prolactin, testosterone, 17beta-oestradiol and sexual hormone-binding globulin (SHBG)]. Significant correlations were found: (i) weight, waist circumference and hip circumference versus testosterone level, SHBG level, and testosterone/17beta-oestradiol ratio; (ii) hip circumference versus sperm concentration; (iii) waist circumference and hip circumference versus sperm count, total motile sperm cell number and rapid progressive motile sperm count; (iv) weight versus total sperm count and total motile sperm cell number; (v) waist circumference and hip circumference versus prolactin level (positively) and SHBG (negatively); (vi) waist circumference and waist/hip ratio versus semen volume. It can be concluded that the waist/hip ratio is correlated with the reproductive hormone levels. Although both the waist circumference and hip circumference correlated with the semen characteristics, the waist/hip ratio did not.

Each testis is surrounded by the tunica albuginea, a dense connective tissue layer that provides structural support and protection. This layer is covered by an outer serous membrane called the tunica vaginalis, which helps reduce friction...
