Human eggs grown to maturity in lab, signals breakthrough in fertility treatment

Scientists have grown human egg cells to full maturity in the lab in a potential breakthrough for fertility treatment, they announced in a study published on Friday. Researchers in New York and Edinburgh developed a new method to grow eggs from very early-stage cells obtained from ovary tissue, a team reported in the journal Molecular Human Reproduction. The eggs were grown to the point at which they could be fertilised. This had previously been achieved with mouse egg cells, while human eggs had been successfully cultivated starting from a much…

Men, take note: Bariatric surgery may reduce your fertility rate

Men undergoing bariatric surgery may be at increased risk of sperm aberrations and lower fertility rates despite improvements in weight, androgen levels and sexual quality of life. Researchers discussed the possible impact of Roux-en-Y gastric bypass (RYGB) on male reproductive capability. Previous research suggested that weight loss through bariatric surgery can help combat premature ageing. The team compared the long-term effects of weight loss following RYGB among a group of sexually active men attempting to conceive with a partner to the semen parameters and fertility of obese men who did not…

Chemotherapy may affect baby girls’ fertility in adulthood

Chemotherapy may affect baby girls’ fertility in adulthood (Harry Sieplinga/Getty Images) Chemotherapy treatment undertaken by women during their pregancy may negatively affect their unborn baby girls’ fertility in later adulthood, warns a study.   The findings showed that a drug called etoposide can damage the development of mouse ovary tissue grown in the lab. Etoposide is used to treat several types of cancer and is considered safe for use in pregnancy because it has a low risk of miscarriage and birth defects. However, little is known about the longer terms…
