Exposure to chemicals may reduce the size of ovarian reserve and linked to lower egg counts in humans

Fertility in women is dependent on ovarian follicles that contain immature oocytes. All follicles are formed during fetal development and should last for the reproductive lifespan of the woman. At most, there are a few million non-growing follicles in the ovaries of the female fetus during mid-gestation, and thereafter, the numbers decrease. At the onset […]

Propulsion of sperm and how […]

Does coenzyme Q10 supplementation improve fertility outcomes?


Increased oxidative stress has been identified as a pathogenetic mechanism in female infertility. However, the effect of specific antioxidants, such as coenzyme Q10 (CoQ10), on the outcomes after Assisted Reproductive Technologies (ART) has not been clarified.

Hair sample tests may give women more accurate fertility predictions


Women wanting to know how many eggs they have left may in future be able to have their hair tested to reveal their hormone levels. A signalling chemical related to women’s fertility called anti-Müllerian hormone (AMH) is incorporated into hair shafts while they are still underneath the skin. Testing the hair may give a better […]
