Researchers from CRCHUM unveiled a mechanism that likely contributes to the low level of pregnancy success in some fertility clinics. Healthy cells usually have one nucleus, but many fertility clinics transfer so-called 'binucleated embryos' with two nuclei back to patients. The study found that binucleation increases the chances of an...

A recent study published in Human Reproduction found that women who consume more fast food and less fruit take longer to become pregnant. The research, which analyzed data from over 5,500 women, suggests that a diet rich in fruits and low in fast food can improve fertility and reduce the time it takes to get pregnant.
Chemotherapy-induced DNA damage triggers apoptosis in oocytes due to p63 activation. Researchers found that inhibiting specific enzymes can prevent this process, offering new hope for fertility preservation.
