• Hormones play an important role in both female and male
• The ovaries are the main source of estrogen, which is responsible for the development of secondary sexual characteristics such as breast growth and widening of hips.
• Testes produce testosterone, which stimulates sperm production
• The system involved sexual reproduction called the reproductive system
• Hypothalamus causes the release of hormones from the pituitary gland
• The hypothalamus sends a gonadotropin-releasing hormone (GnRH) to the anterior pituitary
• The GnRH causes the release of Follicle stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary to the blood.
• Gonadotropin releasing hormone (GnRH) gland is hypothalamus.
• Oestrogen is produced by follicles in the ovary.
• Gonadotropin releasing hormone (GnRH) Stimulates the production and release of follicle-stimulating hormone (FSH) and luteinizing hormone
• Stimulates the production and release of follicle-stimulating hormone (FSH) and luteinizing hormone


  Gonadotropin releasing hormone (GnRH)
• Luteinizing hormone stimulates production of hormones (testosterone and androgen) by the gonads
• Testostetone regulates sperm cell production and secondary sex characteristics
