Some athletes take “steroids” in an attempt to enhance their physical performance. This can lead to decreased sperm production and even sterility. What is the most likely explanation for this effect?
- a)Interference in the proper negative feedback control of testosterone by luteinizing hormone.
- b)Increased stimulation of the anterior pituitary to produce luteinizing hormone.
- c)Suppression of the natural production of thyroxin due to the destruction of thyroid tissue.
- d)Excessive diversion of protein and other metabolites from the gonads to muscle tissue.
Correct answer is option 'A'. Can you explain this answer?

A negative feedback system occurs in the male with rising levels of testosterone acting on the hypothalamus and anterior pituitary to inhibit the release of GnRH, FSH, and LH. The Sertoli cells produce the hormone inhibin, which is released into the blood when the sperm count is too high.

Understanding the Effects of Steroids on Sperm Production
Steroids, particularly anabolic steroids, are synthetic derivatives of testosterone. Athletes may use these substances to enhance muscle mass and physical performance, but they can have significant negative effects on reproductive health.
Mechanism of Action
- When steroids are introduced into the body, they increase the levels of testosterone.
- This surge in testosterone disrupts the body's natural hormonal balance.
Negative Feedback Control
- The hypothalamus and anterior pituitary gland regulate testosterone levels through a negative feedback system.
- Normally, increased testosterone levels signal the hypothalamus to reduce gonadotropin-releasing hormone (GnRH) and inhibit the anterior pituitary from producing luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
Impact of Steroid Use
- With the intake of anabolic steroids, the body perceives an excess of testosterone.
- This leads to decreased production of LH and FSH due to the negative feedback mechanism.
- Since LH and FSH are crucial for stimulating the testes to produce sperm and testosterone, their suppression results in reduced sperm production.
Consequences
- Prolonged use of steroids can lead to testicular atrophy (shrinkage of the testes) and infertility.
- The body’s reliance on external testosterone also inhibits its own production, potentially leading to sterility.
In conclusion, the most likely explanation for decreased sperm production and sterility in athletes who take steroids is the interference in the proper negative feedback control of testosterone by luteinizing hormone. This hormonal imbalance disrupts the delicate system necessary for healthy sperm production.
