Study Notes
Learning Objectives
- Understand reproductive organs and their functions.
- Comprehend reproductive processes: menstruation, fertilization, and pregnancy.
- Learn care techniques for reproductive organs and prevention of sexually transmitted diseases.
Male Reproductive System
- Composed of organs responsible for sperm production, storage, and transport.
- Testes function to produce sperm and regulate temperature crucial for sperm viability.
- Epididymis serves as a storage area for mature sperm linked to the vas deferens.
- Vas deferens transports sperm and semen to the urethra during ejaculation.
- Leydig cells produce testosterone, influencing male traits and sexual behavior.
Female Reproductive System
- Includes organs responsible for ovum production, fertilization, and nurturing embryos.
- Ovaries are responsible for ovum and hormone (estrogen and progesterone) production.
- Fallopian tubes catch ovaries post-ovulation, serving as the fertilization site.
- Uterus provides an environment for embryo development, functioning as a birth canal.
Sperm Structure and Production
- Sperm production occurs in the seminiferous tubules located within the testes.
- Spermatogenesis involves mitotic divisions of primordial germ cells leading to mature sperm.
- Primary spermatocytes undergo meiosis to form secondary spermatocytes and eventually spermatids.
Hormonal Control
- Testosterone governs the growth, structure, and function of male reproductive traits.
- Secondary sexual characteristics include facial hair and voice deepening, stemming from hormonal influences.
Key Processes
- Menstruation involves the shedding of the uterine lining in the absence of fertilization.
- Fertilization occurs when sperm successfully meets an ovum, often in the fallopian tubes.
- Pregnancy is marked by the implantation of a fertilized ovum in the uterine lining, leading to embryo development.
