Male infertility prevents many couples from being able to conceive a child and a new study published in the journal Nature Communications has found a specific protein that is a major determining factor in determining a sperm’s ability to fertilize an egg.
To better understand the causes of male infertility, a team of Bay Area researchers is exploring the factors, both physiological and biochemical, that differentiate fertile sperm from infertile sperm.
Scientists in Mainz and Aachen have discovered a new mechanism that controls egg cell fertility and that might have future therapeutic potential.
University of Montreal researchers found that changes in gravity affect the reproductive process in plants.
Male fertility is one of the most controversial issues in medical science. Recent studies have shown that some medical procedures can harm male fertility while others have shown foods that actually boost it.
An increasing number of men suffer from fertility problems, especially in western society. The general belief is that many problems may be related to stress but it is possible that some of them may arise because men simply have intercourse too infrequently.
