Patient's question:
It's been almost a year since we got married, but my wife hasn't been able to get pregnant yet. She has been to the hospital for multiple checkups, and everything has been normal. Out of desperation, I plan to go to the hospital in two days for infertility testing. Could you please tell me what sperm is composed of?Doctor's answer:
Hello, semen is composed of sperm and seminal plasma, with seminal plasma accounting for more than 90% of the volume of semen. Sperm is produced by the testes and matures in the epididymis before being released through the ducts of ejaculation. Seminal plasma is primarily a mixture of secretions from glands such as the prostate, seminal vesicles, and bulbourethral glands, and also includes small amounts of testicular fluid and epididymal fluid. In addition to containing large amounts of water, fructose, proteins, and peptides, seminal plasma also contains various other substances such as carbohydrates, enzymes, and inorganic salts, which can provide nutrition and energy for sperm.
