The promise of stem cell therapy may lie in uncovering how adult cells revert back into a primordial, stem cell state, whose fate is yet to be determined. Now, cell scientists at the Johns Hopkins University School of Medicine have identified key molecular players responsible for this reversion in fruit fly sperm cells. Reporting online this week in Cell Stem Cell, researchers show that two proteins are responsible redirecting cells on the way to becoming sperm back to stem cells."We knew...

A U.S. expert on urological conditions advises parents to take action if their son complains of testicular pain. Sandra Vassos of the American Urological Association Foundation says if the testicular pain is sudden and severe and there is swelling on one side, the boy may have testicular torsion and should be taken to an emergency room. Testicular torsion is very rare, but can be serious if not treated promptly, Vassos says. The condition occurs when the spermatic cord -- a cord by which a...

Attractive males release fewer sperm per mating to maximize their chances of producing offspring across a range of females, according to a new paper on the evolution of ejaculation strategies. The findings by researchers at UCL (University College London) and the University of Oxford suggest that, paradoxically, matings with attractive males may be less fertile than those with unattractive ones.In a paper to be published in the journal American Naturalist, the team mathematically modeled a...

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. Although male mice lacking this protein, Gpx5, had normal looking sperm and were equally as efficient as normal male mice at fertilizing female mice, an increased incidence of miscarriages and fetal developmental defects were observed when...

New research from Spain shows that men who eat healthier diets might also have healthier sperm."A healthy, well-balanced diet is not just important for preventing diseases like diabetes, high cholesterol, or hypertension, but it may be useful for preserving or improving your reproductive health too," Dr. Jaime Mendiola of the University of Murcia, the lead researcher on the study, told Reuters Health via e-mail.Mendiola and his team noted in the journal Fertility and Sterility that studies...

Low antioxidant intake is associated with low reproductive capacity in semen. This is the finding of a new study carried out in two infertility centres in Alicante and Murcia, and which has been published online in the journal Fertility and Sterility."Our previous research study, published in March, showed that men who eat large amounts of meat and full fat dairy products have lower seminal quality than those who eat more fruit, vegetables and reduced fat dairy products. In this study, we...

The male prostate gland acts as an exocrine gland in the male reproductive system. It is a firm, partly muscular, chestnut sized gland near the neck of the urethra in males. Formation and Orientation The prostate is usually formed within the ninth week of the embryonic stage in reproductive development. The prostate can be separated into either “lobes” or “zones”. When looking at a prostate divided into zones, there are four distinct regions. The first zone is the Peripheral...

Testicles

The testicles are the male reproductive organs that serve as a part of both the nervous and reproductive systems, acting as the ovaries’ counterpart. The testicles work to produce sperm and introduce chemicals such as testosterone. Formation and Orientation There are normally two testicles in the average male anatomy. These can be found in the protective sack called the scrotum. Two phases mark the growth of the testicles. During the embryonic stage, there is a possibility of this...
