There are a few natural reasons why one testicle is bigger than the other: Normal development – Just like one foot may be ...

Study reveals how hypoxia-linked conditions like sleep apnoea and varicocele threaten male fertility and offspring health.

A lack of oxygen in the testes, or testis hypoxia, caused by chronic medical conditions -- such as sleep apnoea or varicocele -- can be a sustained threat to reproductive health, lead author, Tessa ...

Medical conditions that deprive the testes of oxygen, such as sleep apnoea, may be contributing to the decline in male fertility observed over the past 50 years.

The immediate effects of low oxygen on sperm quality are temporary, but new evidence suggests that a long-term decrease in ...

According to a report published in the journal Nature Reviews Urology, less oxygen reaching the testes impacts both the ...

High-altitude hiking, sleep apnoea and other conditions which deprive a man's testes of oxygen, could be contributing to a ...

A new study links oxygen deprivation caused by high-altitude hiking, sleep apnea, and varicocele to declining male fertility over the past 50 years. This shows the impact of "testis hypoxia" on sperm ...
