A hormone is a chemical released by one or more cells that affects cells in other parts of the organism. Only a small amount of hormone is required to alter cell metabolism. It is essentially a chemical messenger that transports a signal from one cell to another.

Study identifies regional differences in women with polycystic ovary syndrome

The environment could be playing a critical role in the expression of polycystic ovary syndrome (PCOS) in women living in Alabama, as compared to women in California, according to a new study published in the Journal of Clinical Endocrinology & Metabolism.

Men are biologically older than women, study finds

A study at the University of Jyväskylä found that men are biologically older than women. The observed sex difference is partially explained by men's more frequent smoking and larger body size.

Age plays a more important role than genetics in affecting gene expression profiles as we get older

Amid much speculation and research about how our genetics affect the way we age, a University of California, Berkeley, study now shows that individual differences in our DNA matter less as we get older and become prone to diseases of aging, such as diabetes and cancer.

Wear and tear from lifelong stress can lead to increased risk of dying from cancer

The wear and tear on the body from chronic and lifelong stress can also lead to an increased risk of dying from cancer, Medical College of Georgia researchers report.

$80,000 and 5 ER visits: An ectopic pregnancy takes a toll despite NY’s liberal abortion law

When Sara Laub's period was late, the New York City resident shrugged it off. She'd used an intrauterine device, or IUD, for three years and knew her odds of getting pregnant were extremely slim. But after 10 days had passed, Laub, 28, took a home test in early July and got unwelcome news: She was pregnant.

How COVID-19 affects the female reproductive system

A new review in the Biology of Reproduction journal analyzed the relationship between the immune system and the female reproductive system while focusing on the effects of COVID-19-associated immune responses on the reproductive system. The study searched PubMed to identify peer-reviewed literature in English up to May 2022 and finally included 83 studies.

Study investigates associations between potential endocrine-disrupting chemicals and female fertility

About one in six women of reproductive age face difficulties in conceiving or carrying a pregnancy to term. Although there has been a global increase in the use of assisted reproductive technologies (ARTs), the success rate of live birth has remained almost the same.

Oxytocin induces epicardial cell proliferation, study finds

The neurohormone oxytocin is well-known for promoting social bonds and generating pleasurable feelings, for example from art, exercise, or sex. But the hormone has many other functions, such as the regulation of lactation and uterine contractions in females, and the regulation of ejaculation, sperm transport, and testosterone production in males.
