Changes in Fertility and Hormone Replacement Therapy in Kidney Disease

Infertility is common among men and women with CKD and fertility is usually restored with successful kidney transplantation. There are many causes of infertility in those on dialysis, including sexual dysfunction and impaired spermatogenesis and ovulation resulting from an altered hormonal milieu. There is little information about infertility in CKD, but it is clear that ESRD results in low rates of pregnancy in women. Early reports of increased pregnancy rates in women on nocturnal hemodialysis suggest that this modality may improve the abnormal reproductive hormonal milieu of ESRD; small studies of men on dialysis also suggest this. Just as the specific causes of infertility in men and women with CKD/ESRD are unknown, we also lack information about the appropriateness of hormone replacement in these patients. This paper reviews these linked issues, pointing out the lack of data upon which to base clinical decision-making about these quality-of-life issues in our CKD/ESRD patients.
