Preeclampsia in pregnancy reduces risk of some cancers but raises endometrial cancer odds

Women with preeclampsia in their first pregnancy had a lower risk of developing breast, cervical, and lung cancer later in life, but a higher risk of endometrial cancer. The large Nordic cohort study also found that siblings of women with PE had a modestly reduced risk of cancer, particularly lung cancer.

Embryos from women with PCOS carry distinctive epigenetic memory

Novel research presented today at the 41st Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) has found that embryos from women with polycystic ovary syndrome (PCOS) carry a distinctive 'epigenetic memory' that could explain why the condition often runs in families.

Once-monthly obesity injection shows double-digit weight loss in major clinical trial

Researchers found that once-monthly maridebart cafraglutide led to substantial weight loss and improved glycemic control in adults with obesity, with or without diabetes, in a phase 2 randomized trial. The drug demonstrated an acceptable safety profile and supports further study in phase 3 trials.

Mayo Clinic researchers discover how ovarian cancer may begin

Little is known about what causes ovarian cancer, and there is no way to detect it early yet. About 75% of the time when someone is diagnosed with ovarian cancer, it has already progressed to stage 3 or stage 4, which means it has spread to other parts of the body.

Mediterranean diet boosts sperm health while ultra-processed foods lower fertility, study finds

Adherence to the Mediterranean diet is linked to improved sperm parameters in men, while high intake of ultra-processed foods is associated with poorer semen quality. These associations are strongest in men with normal FSH levels, suggesting dietary patterns may influence male fertility.
