After puberty, it takes about 3 months for spermatozoa to develop and mature from spermatogonia to spermatozoa in the male body. The spermatogonia located at the base of the epithelium of the seminiferous tubules first undergo mitosis, followed by meiosis to form primary spermatocytes, secondary spermatocytes, and ultimately spermatocytes, or spermatozoa, and the spermatozoa in the testes need to acquire the ability to move and be fertilized in the epididymis. This takes about three months. Usually, during ejaculation, sperm stored in the epididymis mixes with secretions from other parts of the body, such as the prostate and urethral bulbourethral glands, to form semen for discharge. Generally, the expelled sperm can maintain activity in the woman’s body or other suitable environment for 24 to 48 hours. Patients need to consult the doctor for examination and early treatment if they feel unwell.
