Hello there,

The main function of inhibitory hormones in human reproduction is to regulate hormone secretion and maintain reproductive balance. Key inhibitory hormones include:

1. Gonadotropin-Inhibitory Hormone (GnIH)

• Inhibits GnRH release, reducing LH and FSH secretion
  
  2. Inhibin

• Suppresses FSH secretion to prevent overstimulation of ovaries and testes.
  
  3. Prolactin-Inhibiting Hormone (PIH/Dopamine)

• Prevents unnecessary prolactin release, regulating milk production.
  
  4. Anti-Müllerian Hormone (AMH)

• Regulates follicular development and inhibits Müllerian duct formation in males.
  
  5. Progesterone (Negative Feedback)

• Suppresses GnRH, LH, and FSH during the luteal phase, preventing ovulation.

These hormones ensure proper reproductive function and hormonal balance.
