Dads-to-be: Daily sex urged Jul 3, 2009
Dr Greening said it was likely frequent ejaculation improved the quality of sperm by reducing the length of time they were exposed to potentially damaging molecules called reactive oxygen species in the testicular ducts and epididymis. Page. (Sydney Morning Herald -- Sport)
Daily sex urged for budding dads Jul 2, 2009
Dr Greening said it was likely frequent ejaculation improved the quality of sperm by reducing the length of time they were exposed to potentially damaging molecules called reactive oxygen species in the testicular ducts and epididymis. However, 22 men recorded an increase in damage of 10 per cent on average and Dr Greening said these men may have a different explanation for their sperm DNA damage.

1Men Told Have Sex Daily to Boost Sperm Quality, Fertility» Jul 2, 2009
When men go without ejaculating, the number of sperm stored in the epididymis at the top of the testicle increases, hence the standard advice to have sex every two to three days if you are trying to conceive. The longer that sperm sits in the epididymis, however, the more genetic damage it accumulates through exposure to heat and to oxygen free radicals. (Fox News)
Daily Sex Helps Reduce Sperm DNA Damage And Improve Fertility Jul 2, 2009
Dr Greening said he thought the reason why sperm quality improved with frequent ejaculation was because the sperm had a shorter exposure in the testicular ducts and epididymis to reactive oxygen species very small molecules, high levels of which can damage cells. The remainder of the men who had an increase in DFI might have a different explanation for their sperm DNA damage, he concluded. (Science Daily)
Protein That Protects Sperm, Reduces Miscarriage Rates Identified Jun 27, 2009
Joel Drevet and colleagues, at Clermont Universit;, France, have identified a protein that helps protect immature mouse sperm after they have been released into a region of the testis known as the epididymis, which is where they undergo maturation ... Further analysis indicated that Gpx5 acts as an antioxidant in the epididymis, protecting the sperm from oxidative stress. (Science Daily)

Key Sperm-binding Proteins Cloned Mar 18, 2009
According to Dr.Manjunath and his team, these species produce small amounts of BSPs only in the epididymis, a duct that connects the testes to the urethra. "For a few years, we were looking in the wrong place," says Dr. Manjunath. (Science Daily)
Vasectomy Reversal Procedures Feb 25, 2009
If a vasovasostomy cannot be performed due to a blockage or other problem in the vas deferens, the surgeon will attempt to connect the vas deferens directly to the epididymis (a coiled sperm receptacle on the testicle). The surgeon won t be certain which procedure will be required until the patient is on the table, and both sides may require a different technique. (Suite101.com)
How 'Companion' Cells To Sperm Protect Them From Genetic Damage Feb 10, 2009
A new study provides evidence that the body recognizes and tags defective sperm cells while they undergo maturation in the epididymis, a. (June 23, 2004) Reproductive biologists at Kyoto University have succeeded in producing the first animal offspring with transgenic material carried directly from sperm stem cells "infected" by a retrovirus.

Sheep and Goat Diseases Outlined From A to Z (15) Feb 9, 2009
A venereal disease of rams, epididymitis is an inflammation of the epididymis, the tubular portion of a ram's reproductive system that collects sperm and stores it for transport. Caused by bacteria, the disease can result in infertility and is contagious to other rams as well as ewes. (Agri-View, WI)
