Zebrafish reveal how two genes independently drive sensory organ regeneration

Researchers identified that two cyclin D genes, ccndx and ccnd2a, independently regulate distinct stem and progenitor cell populations during zebrafish sensory organ regeneration. The findings reveal that regeneration can proceed via alternative pathways even when one gene is disrupted, providing new insight into tissue repair mechanisms.

California’s much-touted IVF law may be delayed until 2026, leaving many in the lurch

California lawmakers are poised to delay the state's much-ballyhooed new law mandating in vitro fertilization insurance coverage for millions, set to take effect July 1. Gov. Gavin Newsom has asked lawmakers to push the implementation date to January 2026, leaving patients, insurers, and employers in limbo.

Global female infertility rates surge, hitting women in their late 30s hardest

Researchers analyzed global data from 1990 to 2021 and found that over 110 million women worldwide were affected by infertility, with a significant rise in age-standardized rates. The study highlights shifting trends, with the greatest burden among women aged 35–39, and projections showing further increases in age-standardized rates by 2050.

Cutting back on sugary drinks may protect men’s fertility, review finds

Regular consumption of sugar-sweetened beverages is associated with lower sperm count, motility, and increased DNA damage, potentially impairing male reproductive health. This narrative review highlights dose-response effects, mechanisms, and research gaps, calling for further studies on diverse populations.

Simple oral swab test could revolutionize IVF success rates

About 15 per cent of all couples of reproductive age are involuntarily childless. A major reason why so many need assisted reproduction is that nowadays more and more people are putting off starting a family.
