Frequent Ejaculation May Boost Sperm Quality and Fertility
A large meta-analysis of about 55,000 men shows that longer gaps between ejaculations increase sperm DNA damage and oxidative stress, lowering quality, while shorter abstinence can yield fresher, more motile sperm. WHO guidelines of 2–7 days for semen testing may prioritize count over quality, and a recent IVF trial found higher pregnancy rates with shorter abstinence. For natural conception, a balance between abstinence duration, sperm quantity and quality is likely best, with freshness often more important in assisted reproduction.
