Study shows harmful sperm mutations rise with men's age
New research reveals that genetic mutations in men's sperm, which can lead to diseases in offspring, increase with age due to evolutionary selection within the testes. Scientists used advanced sequencing to analyze sperm from 81 men aged 24 to 75, finding that harmful mutations affect 2 percent of sperm in early 30s men but rise to 4.5 percent in 70-year-olds. The findings, published October 8 in Nature, highlight risks for future generations.
Trump unveils plan to cut IVF and infertility drug costs
President Donald Trump announced measures on Thursday to reduce the price of in vitro fertilization and infertility treatments, incorporating input from pro-life advocates. The plan includes optional employer insurance coverage for IVF and a new agreement with pharmaceutical firm EMD Serono for discounted fertility drugs. Pro-life groups expressed relief that the policy avoids mandates or subsidies.

Scientists create viable human eggs from skin cells
AI에 의해 보고됨
Researchers at Oregon Health and Science University have successfully generated functional human egg cells from skin cells, which were then fertilized in the lab to produce early-stage embryos. This breakthrough, published in Nature, represents the first time such eggs have been matured and used for fertilization outside the body. The technique could eventually aid infertility treatments and genetic disease prevention.
