  Purpose

Patients with chronic kidney disease (both men and women), especially those with terminal renal failure, manifest infertility. There has been demonstrated several hormonal changes in patients on dialysis. Increased levels of luteinizing hormone (LH) has been seen in men (12). In women the opposite has been reported. The number of spermatocytes is reduced and a disturbance in maturation has been observed.

This project is aimed to study the influence of uremic milieu on fertility in men and women. The hypopituitary/hypothalamus gland axis and hormonal levels will be studied.

Study Start Date: January 2011
Estimated Study Completion Date: August 2016
Estimated Primary Completion Date: May 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts
renal transplant patients
Patients undergoing transplantation
dialysis patients
hemodialysis patients and peritoneal dialysis patients. Before and after a dialysis session
patients with renal insufficiency
outpatient patients with chronic kidney disease stage 2, 3 and 4
Chronic kidney disease
outpatient cohort. Those with mild renal insufficiency

Detailed Description:

Renal elimination of hormones and peptides. By using a human transplantation model the investigators will study changes in hormonal levels before and after a successful transplantation up to 12 months. Hormones: testosterone, SHBG (sex hormone binding globulin), LH (luteinizing hormone), FSH (follicle stimulating hormone), estradiol and inhibin B.

Analysis of sperm quality, concentration, motility, morphology and as well DNA-fragmentation index (DFI) in men with chronic kidney disease. In women the investigators will study the maturation of follicles via vaginal ultrasound. Controls are persons from a study at Dept of Reproductive Medicine.
