8. FUNCTION OF THE MALE REPRODUCTIVE ORGAN produce, maintain and transport sperm (the male reproductive cells) and semen (the protective fluid around the sperm). discharge sperm into the female reproductive tract. produce and secrete male sex hormones.

TESTES SCROTUM EPIDIDYMIS SEMINIFEROUS TUBULES SEMINAL VESICLE URETHRA PENIS PROSTATE GLAND VAS DEFERENS PARTS AND FUNCTION OF THE MALE REPRODUCTIVE ORGAN VAS DEFERENS carries sperm to the penis during the ejaculation PROSTATE GLAND add alkaline fluids that neutralize the vaginal acids URETHRA delivers semen during ejaculation and urine during excretion PENIS muscle that becomes erect during ejaculation or excretion SEMINAL VESICLE add nutrients including fructose sugar for respiration and adds mucus to protect sperms SEMINIFEROUS TUBULES – produces sperm called spermatogenesis EPIDIDYMIS stores and matures sperm TESTES produces testosterone SCROTUM protects and holds the testes

11. HORMONES DESCRIPTION SECRETING GLAND Testosterone It is made in the interstitial cells of the testes TESTES Influencing the development of secondary male characteristics. Maintains reproduction tract Promotes sperm production Influence sex drive and behavior. Gonadotropin Releasing Hormone (GnRH) It is responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary gland. HYPOTHALAMUS Secreted by hypothalamus gland. Causes pituitary to release FSH and LH Testosterones production is regulated by the Negative Feedback.

12. HORMONES DESCRIPTION SECRETING ORGAN Follicle-Stimulating Hormone (FSH) It is released by the anterior pituitary gland. Its presence in males is necessary for the maturation of spermatozoa. ANTERIOR PITUITARY GLAND Promotes/initiates sperm production Releases by pituitary gland Luteinizing Hormone (LH) It is produced by the anterior pituitary gland. It causes the synthesis of the testosterone. ANTERIOR PITUITARY GLAND Assist spermatogenesis and initiates production of testosterone in the testes. Release by pituitary gland.

16. FUNCTION OF THE FEMALE REPRODUCTIVE ORGAN produces the female sex hormones that control reproduction and female eggs (ova) for fertilization Serve as the pathways for the ova (egg cells) to travel from the ovaries to the uterus The womb, responsible for the development of the embryo and fetus during pregnancy Provides a channel for delivery of a newborn from uterus

18. PARTS AND FUNCTION OF THE FEMALE REPRODUCTIVE ORGAN produces the female sex cell and hormones that control reproduction and m aturation of females’ eggs for possible fertilization. pathways for the ova (eggs cells) to travel from the ovaries to the uterus. Fertilization of an egg by sperm normally occurs in this part. Responsible for the development of the embryo and fetus during pregnancy Also commonly known as the “womb” is responsible for the development of the embryo and fetus during pregnancy. In childbirth it expands to provide a channel for delivery of a newborn from uterus. Passage way for the penis to deposit the sperm cell during intercourse Separates the uterus from the vaginal canal; it expands during childbirth to provide a channel for delivery of a newborn from uterus.
