Animal Reproduction 1.1

Hormones in Human Reproduction

• Male Hormone: Testosterone is critical for sperm development
• Female Hormones:
  • Estrogen: Critical for follicle development
  • Progesterone: Sustains pregnancy and inhibits new follicle development
• Hormones in Childbirth and Lactation:
  • Relaxin: Causes ligaments around the birth canal to relax
  • Oxytocin: Causes milk letdown

Male Reproductive System

• Testicles are the site of sperm production and testosterone synthesis
• Sperm contain half of the genetic makeup
• Epididymis is responsible for sperm storage and maturation
• Scrotum protects the testes and regulates temperature to facilitate sperm development

Male Reproductive System

• The testicles are responsible for producing sperm and synthesizing testosterone.
• Sperm cells contain half of the genetic makeup, contributing to the offspring's genetic traits.
• The epididymis stores and matures sperm, preparing them for fertilization.
• The scrotum serves as a protective sac for the testes, regulating temperature to ensure optimal sperm development.
• The vas deferens acts as a transport tube, carrying sperm from the epididymis to the urethra.
• The urethra is a shared passageway for both sperm and urine, allowing for the elimination of waste and the release of sperm during ejaculation.
• The penis is the organ of copulation, facilitating sexual intercourse and reproduction.

Female Reproductive System

• Ovaries are responsible for producing eggs, which contain half of the genetic makeup necessary for fertilization.
• The site of fertilization is the oviducts, where the sperm meets the egg.
• The oviducts also function as a transportation pathway, moving the fertilized embryos to the uterus.
• The uterus is the site where embryonic development takes place during gestation.

Female Reproductive System

• The cervix connects the uterus and vagina, serving as a barrier during pregnancy.
• The vagina is the female organ of copulation during mating and is also the opening of the bladder.
• The vulva is the external opening of the reproductive system.

This quiz covers the role of different hormones in human reproduction, including testosterone, estrogen, progesterone, relaxin, and oxytocin. Learn about their functions in sperm and follicle development, pregnancy, and childbirth.
