Urology, 2009
The increasing incidence of cancer among the reproductive population, especially Hodgkin's disease (HD) and testicular cancer, has been paralleled by a substantial improvement in survival rates. In addition to survival and recurrence rates, preserving future fertility and subsequent offspring welfare have become a main focus of modern treatment ...

Fertility and Sterility, 1988
Serum estradiol (E2) levels were measured in 451 men attending an infertility clinic and 80 fertile men attending for vasectomy. The normal range of E2 levels found in fertile men was 70 to 200 pmol/l. Subfertile men had lower mean E2 levels than fertile men (P less than 0.05), but there was no relationship to obesity, cigarette smoking, age, or the ...

Kisspeptins, Estrogens and Male Fertility
Current Medicinal Chemistry, 2016The control of male fertility requires accurate endocrine, paracrine and autocrine communications along the hypothalamus-pituitary-gonad (HPG) axis. In this respect, the possible interplay between upcoming/classical modulators of reproductive functions deserves attention in that may be a successful tool for the future exploitation of new potential ...
