Currently, it is challenging for researchers to control the differentiation of stem cells in the lab (in vitro). Of particular interest are oocytes, which are female germ cells that develop into eggs. Understanding their development could have far-ranging impacts, from infertility treatment to conservation of endangered species. A new study has successfully induced meiotic (dividing) oocytes from the embryonic stem cells of cynomolgus monkeys, which share many physiological traits with humans. By establishing a culture method for inducing the differentiation of meiotic oocytes, the researchers aimed to shed light on germ cell development in both humans and other primates.

Now, researchers have revealed the dynamics of a new, very young chromosome in fruit flies that is similar to chromosomes that arise in humans and is associated with treatment-resistant cancer and infertility. The findings may one day lead to developing more targeted therapies for treating these conditions.

Researchers identified expression of the gene, Arrdc5, in the testicular tissue of mice, pigs, cattle and humans. When they knocked out the gene in mice, it created infertility only in the males, impacting their sperm count, movement and shape.

Time-restricted fasting is an eating pattern where people limit their food consumption to certain hours of the day. It's a popular health and fitness trend and people are doing it to lose weight and improve their health. But the new study shows that time-restricted fasting affects reproduction differently in male and female zebrafish. Importantly, some of the negative effects on eggs and sperm quality can be seen after the fish returned to their normal levels of food consumption. The research team say that while the study was conducted in fish, their findings highlight the importance of considering not just the effect of fasting on weight and health, but also on fertility.

The study found that male rats who received the drug ifosfamide during adolescence had offspring and grand-offspring with increased incidence of disease. While other research has shown that cancer treatments can increase patients' chance of developing disease later in life, this is one of the first-known studies showing that susceptibility can be passed down to a third generation of unexposed offspring.

This helps cells avoid creating reactive oxygen species, harmful molecules that can accumulate, damage DNA and cause cell death. The findings explain how human egg cells remain dormant in ovaries for up to 50 years without losing their reproductive capacity. The findings could lead to new strategies to preserve the ovarian reserves of women undergoing cancer treatment, as well as open new lines of research that explain why one in four cases of infertility are unexplained.
