BACKGROUND: Renal transplantation (RT) is the most common solid organ transplant procedure. Several studies have reported on gonadal function in male and female RT recipients with controversial results. METHODS: Forty consecutive patients (20 male, 20 female) with a fully functioning allograft (serum creatinine 0.8-1.3 mg/dl) for at least 15 months after RT were included in the study. Their ages ranged from 23 to 44 years (median 38) and their post-RT follow-up lasted 15-86 months (median 23). FSH, LH, prolactin, 17-beta-estradiol, testosterone, androstenedione and dehydroepiandrostrone were determined in all patients and compared with a group of 80 healthy subjects. Pelvic ultrasonography was performed in all participants. RESULTS: Testosterone was below the normal range in 70% of male patients and within the lowest third in the remainder; a lack of LH increase indicated an inhibition of the reproductive axis. Male testosterone values were negatively influenced by calcineurine inhibitors treatment (P < 0.005), but positively influenced by a better graft function (P < 0.0001). Testicular and prostate volumes were reduced with respect to controls, with the latter related to circulating testosterone levels. Ten of the women (50%) had menstrual cycle disorders after RT, three being affected by transient, and three by persistent, amenorrhea. Another two patients had had transient polymenorrhea. In four women (20%), a premature ovarian failure was diagnosed. No relationship was found between female reproductive function and age, graft function or duration of the post-transplant period. Prolactin was lower in patients on calcineurin inhibitors (P < 0.01). CONCLUSIONS: Abnormalities of the reproductive system were frequent after successful RT in both genders.

Abstract

BACKGROUND: Renal transplantation (RT) is the most common solid organ transplant procedure. Several studies have reported on gonadal function in male and female RT recipients with controversial results. METHODS: Forty consecutive patients (20 male, 20 female) with a fully functioning allograft (serum creatinine 0.8-1.3 mg/dl) for at least 15 months after RT were included in the study. Their ages ranged from 23 to 44 years (median 38) and their post-RT follow-up lasted 15-86 months (median 23). FSH, LH, prolactin, 17-beta-estradiol, testosterone, androstenedione and dehydroepiandrostrone were determined in all patients and compared with a group of 80 healthy subjects. Pelvic ultrasonography was performed in all participants. RESULTS: Testosterone was below the normal range in 70% of male patients and within the lowest third in the remainder; a lack of LH increase indicated an inhibition of the reproductive axis. Male testosterone values were negatively influenced by calcineurine inhibitors treatment (P < 0.005), but positively influenced by a better graft function (P < 0.0001). Testicular and prostate volumes were reduced with respect to controls, with the latter related to circulating testosterone levels. Ten of the women (50%) had menstrual cycle disorders after RT, three being affected by transient, and three by persistent, amenorrhea. Another two patients had had transient polymenorrhea. In four women (20%), a premature ovarian failure was diagnosed. No relationship was found between female reproductive function and age, graft function or duration of the post-transplant period. Prolactin was lower in patients on calcineurin inhibitors (P < 0.01). CONCLUSIONS: Abnormalities of the reproductive system were frequent after successful RT in both genders.
