Polycystic ovarian syndrome (PCOS) is a disease that affects one in five women, but until now its cause was unknown. Maybe this is a breakthrough to stop having irregular periods and facial hair.
A study published in Nature Medicine revealed that the cause of cysts in the ovaries could be the antimüllerian hormone.
The Center for Assisted Reproduction in Connecticut explains that this hormone is secreted by the ovarian follicles and helps measure the ovarian reserve:
«The ovarian reserve is a concept that encompasses both the amount of oocytes (ovules) that are left to the woman and the quality of them. In other words, the analysis of this hormone serves to see how many valid ovules the woman still has in the ovaries. "
However, little was studied about its relationship with abnormal growths in the ovaries. For the investigation, an experiment was carried out with female mice to which they injected the antimülleriana hormone because these mammals also produce it.
After pregnancy, the mice gave birth to daughters who developed PCOS and related symptoms, for example, fertility problems, delayed puberty, and erratic ovulation.
Finding the possible cause of PCOS is already an achievement in itself since it could not be determined, but the scientists made an even more impressive achievement: to reverse it.
According to the study, this syndrome could be treated prenatally with injections of a drug called cetrorelix. And, even more surprisingly, the intermittent administration of this substance to adult mice reduced reproductive alterations.
Hopefully, these advances can soon become a treatment for women with PCOS.
