Sperm itself is not a hormone; rather, it is a reproductive cell. However, seminal plasma, the fluid that carries sperm, contains several hormones.
Seminal plasma is more than just a transport medium for sperm. It contains various substances, including hormones, that contribute to sperm function and fertilization.
Hormones in Seminal Plasma
Research has identified several hormones present in human seminal plasma. According to studies, some of these include:
- Gonadotropins: These are hormones that stimulate the gonads (testes in males).
- Luteinizing Hormone (LH): LH plays a crucial role in stimulating testosterone production in the testes.
- Follicle Stimulating Hormone (FSH): FSH is important for sperm production (spermatogenesis).
- Prolactin: Prolactin is involved in various reproductive functions.
These hormones are thought to be transported from the blood to the semen via accessory sex organs. Therefore, while sperm is not a hormone, the fluid surrounding it contains hormones essential for male reproductive function.
