The epididymal immune balance: a key to preserving male fertility

Cauda epididymal proteins and fertility

Fertility was expressed as the percentage point deviation of bull non-return rate (PD) from the average fertility of all bulls at an artificial insemination center. Number of services for each bull ranged from 1,07...

Epididymal expression of the forkhead transcription factor Foxi1 is required for male fertility.

An essential aspect of male reproductive capacity is the immediate availability of fertilization-ready spermatozoa. To ensure this, most mammals rely on post-testicular sperm maturation. In epididymis, germ cells are matured and stored in a quiescent state that readily can be altered to produce active spermatozoa. This depends on active proton secretion into the epididymal lumen. We have identi...

long-term effects of betamethasone on epididymal tissue, epididymal sperm counts and fertility in male mice

recent studies show that synthetic glucocorticoids alter testicular homeostasis, in this regard, the influence of betamethasone as a glucocorticoid widely used on histological changes, epididymal sperm counts and fertility was explored in male mice. the study sample (50 mice) was allocated to 3 treatment groups, placebo and a control group. control group was no injected. only normal saline was ...

Long-term regulation of male fertility by norethisterone enanthate 'epididymal' implants: effect on libido and fertility of rabbits.

Bilateral insertion of silastic capsules releasing 38-44 micrograms norethisterone enanthate/24 h into the epididymal fat-pads was found to induce complete azoospermia leading to infertility in adult male rabbits 8 weeks after insertion of the progestin implants. The treatment did not exert any inhibitory effects on the libido and sexual behaviour of the animals as judged by objective parameter...
