Male infertility breakthrough: Researcher creates sperm cells out of germ cells

Wednesday, November 30th, 2011

Here at Reproductive Science Institute, we like to stay on top of the latest in fertility research, and a breakthrough was disclosed last week that we thought was interesting and exciting enough to share.

 In a study conducted on mice, researchers at Ben-Gurion University of the Negev in Israel produced sperm cells from mouse testicular germ cells. The research was conducted by Professor Mahmoud Huleihel. “It may open strategies for infertile men who cannot generate sperm, and/or pre-pubertal cancer patients at risk of infertility due to radiotherapy,” Huleihel said. Results of the study were published Nov. 7 in the Asian Journal of Andrology.

 The fact that science is creating sperm cells from germ cells is thrilling, particularly for the hope and promise it gives to infertile men who have dreams of fathering their own biological children. We will continue to follow this and other exciting research in the field of fertility, and bring our readers the latest news directly from the labs.

Men – Quit Smoking If Fertility Is an Issue

Friday, September 10th, 2010

If you’re a male and you and your partner are having trouble conceiving a child naturally, the blame may lay with one of your habits — smoking.

As a recent WebMD article notes:

What appears to be happening is that smoking-damaged sperm lose much of their ability to fight off destructive oxygen molecules — free radicals — in the seminal fluid. Interestingly, in addition to making spermcells more sensitive to oxidative stress, smoking itself increases the concentration of free radicals in the seminal fluid.

The upshot of this finding is that the damage to sperm appears to be temporary.  This means if a male quits smoking, within several months he can, for all intents and purposes, reverse the fertility issues caused by smoking.
