Men diagnosed with infertility have a higher risk of developing other general health ailments, including diabetes, ischemic heart disease, alcohol abuse and drug abuse, compared with fertile men, according to a study.
A new technique developed by a team of researchers affiliated with a number of facilities in China allows medical practitioners involved in IVF treatment to more easily weed out embryos with genetic defects prior to fertilization and implantation of a zygote into a host uterus.
Humans and worms are connected by a common ancestor that lived more than 700 million years ago and shared a gene that is required for sperm to function properly at fertilization, research confirms. This discovery could lead to more effective infertility treatments and better contraceptives.
A potential new approach to fertility preservation for young cancer patients has been discovered, which addresses concerns about beginning cancer treatment immediately and the possibility of reintroducing cancer cells during the fertility preservation process.
Compared with receiving chemotherapy alone, women with breast cancer who also received the hormonal drug triptorelin to achieve ovarian suppression had a higher long-term probability of ovarian function recovery, without a statistically significant difference in pregnancy rate or disease-free survival, according to a study.
The potent humanin analogue protects male germ cells, which are essential to fertility, and white blood cells, which are the soldiers in the body's defense system, during chemotherapy, new research shows.
Active and passive smoking are linked to infertility problems and a hastening of the natural menopause before the age of 50, a large study finds.
Fertility experts in Southampton and the Netherlands have identified a specific genetic pattern in the womb that could predict whether or not IVF treatment is likely to be successful.
New research could help to explain why pregnancy becomes less likely as women age and why IVF so often fails.
Scientists have shown for the first time that hormones produced inside the womb play a pivotal role in the early stages of pregnancy.
More than 10% of American women aged 15-44 struggle to conceive or maintain full-term pregnancies, according to the Centers for Disease Control and Prevention (CDC). Assisted reproductive technology (ART), through which eggs are fertilized with sperm in a lab and then returned to a woman's uterus, is often the last resort for reproductively- challenged couples. But the physical, emotional, and financial toll they exact is high because the success rates of ART treatments are low -- only 20-30%, according to the CDC.
