Credit: Dr. KobayashiAccording to a World Health Organization (WHO) study (2017), about half of all infertility is due to men. Semen analysis is considered essential for diagnosis of male infertility, but is not readily available at medical...
by Bob Yirka, Medical Xpress Credit: CC0 Public Domain An international team of researchers has identified multiple X chromosomes that likely contribute to infertility in men. In their paper published in The American Journal of Human Genetics, the researchers describe how they conducted genetic sequencing on genes from male patients suffering from infertility and compared them...
by Ranjith Ramasamy, The Conversation Credit: Pixabay/CC0 Public Domain Contrary to myths circulating on social media, COVID-19 vaccines do not cause erectile dysfunction and male infertility. What is true: SARS-CoV-2, the virus that causes COVID-19, poses a risk for both disorders. Until now, little research has been done on how the virus or vaccines affect the male...

By Michael Irving, October 22, 2020 A potential new treatment for male infertility has been demonstrated in tests on mice. Male infertility is a serious issue, often caused by low sperm counts. Now, researchers at Seoul National University have developed a way to deliver nanoparticles loaded with certain proteins directly into the testes. In tests in mice,...
Hope has emerged for infertile men as scientists at Newcastle University have understood the importance of a gene in regulating the production of fully-functioning sperm. For the first time, experts have identified the role of gene, RBMXL2, which is very similar to a possible infertility gene found on the Y chromosome found only in men....
