Our goal is to evaluate the sexual and testicular (endocrine and spermatic) functions on men submitted to hemodialysis and kidney transplants. Our study is based on 22 patients with chronic kidney disease during hemodialysis and 21 kidney transplanted patients attended on a first aid station special for those cases of previous and post transplant at the Hospital Universitário Walter Cantídio, UFC. The patients were submitted to anamnesis, physical exams and evaluated through a questionary about sexual performance. The endocrine evaluation was made considering the following hormones: FSH, LH, Prolactin and Testosterone. Semen analysis (spermogram) and sperm functional tests (hypo-osmotic test, nuclear chromatin stabilization test and swim-up test) were made. The median scores of the control, hemodialysis and transplant group were respectively: at erectile function 29/27,5/28, at orgastic function 10/10/10, at sexual desire function 10/8/9, at intercourse satisfaction 13/11/12, at satisfaction related to sexual life 10/10/9 proving that there was no significant statistical difference between the groups — excepting the sexual desire component in which the hemodialysis group was bigger than the control group (P = 0.0004). The hormones concentration averages in the hemodialysis and transplant group were respectively: prolactin 17,27/11,4; testosterone 5,25/4,78; FSH 3,65/4,11; LH 7,02/5,9 and it was not verified any significant statistical difference — excepting the prolactin levels that were higher in the hemodialysis group (P = 0,0035). The average and standard deviation from the semen parameter and sperm functional tests on the hemodialysis and transplant group were respectively: volume 1,86±0,85/3±1,9; pH 8±0/8,14±0,24; concentration 25,57±25,7/36,6±37,5; progressive motility 30,29±27,5/33±9,67; vitality 40±16,7/52±12,2; morphology 10,14±6,39/13,67±11,02; stability of nuclear chromatin (stable) 80±2,16/82±3,9; stability of the sperm membrane 59,71±4,61/58,5±4,76; progressive motility after capacitation 48,8±25,19/40,33±16,02; concentration after capacitation 3,42±3,7/7,67±4,18 showing that there was no significant statistical difference. Thus, we can conclude that kidney transplants do not improve the sexual function of patients with cronic kidney disease submitted to hemodialysis. The alteration in hypothalamus-hypophysis-gonad was not significant in both groups studied. However, there was an improvement of the seric prolactin levels on the transplanted group. There was no improvement of the standard spermogram parameter related to kidney transplant, but it was observed a slight alteration concerning the sperm functional tests in both groups that suggests a good forecast of fertility in the group of patients studied.
