Findings from study highlight importance of preconception health for fathers.

COVID-19 vaccination does not affect the chances of conceiving a child, according to a study of more than 2,000 couples that was funded by the National Institutes of Health. Researchers found no differences in the chances of conception if either male or female partner had been vaccinated, compared to unvaccinated couples. However, couples had a slightly lower chance of conception if the male partner had been infected with SARS-CoV-2 within 60 days before a menstrual cycle, suggesting that COVID-19 could temporarily reduce male fertility.

Dr. Grewal has been acting director of the division since February 2020.

Mouse studies targeting gonadotropin regulated testicular helicase (GRTH) appear to be a promising approach.

Mutation in a single gene appears to account for a form of male infertility in which men fail to produce sperm, according to an international study funded in part by the National Institutes of Health. Males with the condition, known as non-obstructive azoospermia, fail to produce any sperm, even though they do not have any obstruction in the ducts through which sperm are released.

Antioxidant supplements do not improve semen quality among men with infertility, according to a new NICHD-supported study.

Dietary supplements containing zinc and folic acid—marketed as a treatment for male infertility—do not appear to improve pregnancy rates, sperm counts or sperm function, according to a study conducted by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), part of the National Institutes of Health.

The mouse X chromosome contains two amplicons—regions in which a single gene is copied multiple times—that appear to control male fertility and offspring sex ratios, an NIH-funded study suggests. The findings could provide insight into male infertility among humans.

Researchers have successfully frozen testicular tissue from monkeys too young to produce sperm and used this tissue to produce a pregnancy resulting in live, healthy offspring. The finding is an early step in the development of a method to store testicular tissue for children before they undergo fertility-destroying treatment for cancer or other disorders. The research team was led by Kyle E. Orwig, Ph.D., of the University of Pittsburgh School of Medicine and was funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), part of the National Institutes of Health.

Proximity to nearby muscle cells may make prostate cancer cells more likely to invade nearby tissues and spread to other organs, according to an early study by researchers at the National Institutes of Health. The presence of muscle cells appears to make cancer cells more likely to fuse two or more cancer cells into a single cell, thereby increasing their invasiveness and ability to spread.

In 2018, researchers funded by NICHD made significant progress in advancing the health and well-being of infants, children, teenagers, and adults across the United States and around the world.

A clinical trial funded by the National Institutes of Health will evaluate a male contraceptive gel for its ability to prevent pregnancy.
