Not having sex for 10 years is likely to lead to weak sperm. Prolonged absence of sexual life may cause male genitals to be congested for a long time without being released, and when sperms are mature and stored in the epididymis and cannot be discharged in a timely manner, it may affect normal sperms, thus resulting in weak sperms. Especially for adult males between 20 and 30 years old with mature reproductive organs, their sex hormones, adrenaline and other related hormones are secreted vigorously, and the long-term absence of sexual life may affect the quality of sperms. Moreover, the testes and epididymis may also experience a localized increase in temperature, leading to the production of low quality sperms and the symptoms of weak sperms. Of course, this does not mean that 10 years of no sex will definitely lead to weak sperm, just that there is such a possibility, and if you have weak sperm, please consult a doctor in time.
