No, frequent ejaculation does not negatively impact sperm production. Spermatogenesis—the production of sperm—occurs continuously and remains unaffected by how often ejaculation occurs.  

However, frequent ejaculation may slightly reduce the volume of semen in each ejaculate, and consequently, the absolute number of sperm present. This is simply because there is less time for sperm to accumulate in the reproductive tract, not because sperm production has decreased.  

Overall, the quality and health of sperm are maintained regardless of ejaculation frequency.
