Researchers make gametes from xenogenic mouse stem cells

Making gametes such as sperm and eggs from pluripotent stem cells, primitive cells that can make all the tissues, greatly contributes to efficient reproduction of livestock animals and future assisted reproductive medicine. Researchers pave the way to achieve this goal using a body of xenogenic animals. ....

Scientist says sperm counts are dropping so low that human reproduction may soon be a thing of the past

Men today only have about half the amount of sperm that their grandfathers did, and the situation is getting progressively worse with each passing day. Shanna Swan, PhD, published a paper back in [.] ....

Sperm counts are falling at a rate that threatens the long-term survival of the human race, a leading epidemiologist has warned.
In a new book, Shanna Swan, an environmental and reproductive epidemiologist at the Icahn School of Medicine in New York, warns there is a looming fertility crisis comparable in its impact to climate change. ....

Retroviruses invading the koala germline contribute to high cancer rates

Retroviruses invading the koala germline contribute to high cancer rates
Koalas are facing multiple environmental and health issues which threaten their survival. Along with habitat loss - accelerated by last year’s devastating bush fires – domestic dog attacks and road accidents, they suffer from deadly chlamydial infections and extremely high frequency of cancer.
An international team of scientists led by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) now demonstrate that a retrovirus invading the koala germline explains the high frequency of koala cancer. The results are reported in the journal
Nature Communications.
The koala retrovirus (KoRV) is a virus that, like other retroviruses such as HIV, inserts itself into the DNA of an infected cell. At some point in the past 50,000 years, KoRV has infected the egg or sperm cells of koalas, leading to offspring that carry the retrovirus in every cell in their body. ....
