New Study! Male sex hormone: Know how does it help in fertility

Did you know that active male hormones are called androgens? Androgens are responsible for the normal functioning of the ovarian follicle. Also, androgens help to release an egg that can be fertilized.

Researchers from Britain and US have given a new insight into the role of male hormones in supporting and disrupting the production of eggs by ovarian follicles.

According to a new that has been published in the journal Endocrinology, measured the production of hormones by the isolated ovarian follicle during its development, using highly sensitive and specific mass spectrometry. 

The Scientists from the University of Birmingham and Northwestern University Chicago showed that ovarian follicles are able to produce active male hormones called androgens from very early stages of development. The scientists also found that androgens are needed for normal function of the follicle, including the successful release of an egg that can be fertilized.

"In women with polycystic ovary syndrome, this self-regulation of the male hormone balance by the follicle is overcome by the very high androgen concentrations in circulation. Thus, we can expect that a decrease in androgens will have a beneficial effect on fertility in affected women," Arlt said.

The researchers used a system pioneered by Professor Teresa Woodruff, from the Women's Health Research Institute at Northwestern University Chicago. This allowed them to embed a follicle isolated from a mouse ovary in a gel and then to observe its development in a dish, until the release of a mature egg at the end of the process.

"We could also show that too much androgen disrupts the development of the follicle, mirroring what we observe in women with polycystic ovary syndrome, who have increased blood androgen concentrations and frequently have difficulties conceiving," said lead author Professor Wiebke Arlt from the Institute of Metabolism and Systems Research at the University of Birmingham.

This was an exciting and unexpected discovery, she said, adding that they could show that the follicle is able to regulate the male hormone balance by decreasing androgen production in response to androgen administration while increasing androgen production when the follicle is treated with androgen receptor blocker
