The levels of the hormones involved in sperm production can be very helpful in determining the cause of sterility in men. The main hormones that are studied after a blood draw in men are:
- Testosterone levels
- should be between 300 and 1000 ng/dL. Amounts of the hormone testosterone outside this range would be indicative of various pathologies in the male.
- FSH
- the values considered normal for this hormone are between 1 and 12 mUI7mL. This hormone is responsible for stimulating the production of Sertoli cells, promoting the synthesis of testosterone and spermatogenesis.
- LH
- A male shows normal LH levels when he is between 2 and 12 mIU/mL. This hormone stimulates the production of Leydig cells, associated with testosterone synthesis.
- Prolactin
- the values considered normal for men are between 2.5 and 17 ng/mL.
