If you abstain from sex for a long time, it may cause poor semen quality, endocrine disorders and increased psychological pressure. 1. Poor semen quality: If abstinence is prolonged, sperms will not be released, and when sperms accumulate in the epididymis, dead sperms may occur. In addition, if the sperms are not expelled from the testes, they will not be able to produce new sperms again. In this way, the quality of sperm will deteriorate. 2. Endocrine disorders: prolonged abstinence may also affect the secretion of sex hormones, which is not conducive to the balance of hormones in the body, which in turn leads to endocrine disorders and even the symptoms of decreased libido. 3. Increase psychological pressure: Sex is one of the ways to reduce pressure. If abstinence for a long time, it is easy to cause sexual tension, resulting in greater psychological pressure. Patients should usually have a scientific sex life, which is still beneficial to physical and mental health.
