Study Notes
Human Reproductive System Overview
- The human reproductive system facilitates offspring creation.
- It's a complex system involving both male and female organs.
- Key functions include gamete production, fertilization, development, and birth.
Male Reproductive System
- Testes: Produce sperm and testosterone.
- Epididymis: Stores and matures sperm.
- Vas deferens: Transports sperm from the epididymis to the ejaculatory duct.
- Seminal vesicles: Produce seminal fluid, a component of semen.
- Prostate gland: Adds fluids to semen, affecting its volume and properties.
- Bulbourethral glands: Produce mucus-like fluid lubricating the urethra.
- Penis: Delivers sperm to the female tract during intercourse.
- Spermatogenesis: Sperm production in testes; involves meiosis and maturation.
- Hormonal Control: Testosterone, regulated by hypothalamus and pituitary, controls spermatogenesis and secondary sexual characteristics.
Female Reproductive System
- Ovaries: Produce ova (eggs) and hormones like estrogen and progesterone.
- Fallopian tubes (oviducts): Transport eggs from ovaries to uterus; site of fertilization.
- Uterus: Hollow, muscular organ where fertilized egg implants and develops.
- Cervix: Lower part of uterus; passageway between uterus and vagina.
- Vagina: Canal receiving penis during intercourse and birth canal.
- Ovulation: Mature egg release from ovary; key stage in menstrual cycle.
- Menstrual Cycle: Cyclic changes in female reproductive system; prepares uterus for pregnancy.
- Hormonal Control: Estrogen and progesterone, regulated by hypothalamus and pituitary, control menstrual cycle and secondary sexual characteristics.
Fertilization
- Fertilization is sperm and egg fusion.
- Typically occurs in fallopian tubes, forming a zygote.
- Sperm reaching the ovum is influenced by various environmental and physiological factors.
Pregnancy
- Fertilized zygote implants in uterine lining (endometrium) initiating pregnancy.
- Fertilization triggers cell division, forming an embryo.
- Embryo develops for a specific gestational period before birth.
- Key embryonic/fetal stages include structure and organ system differentiation.
Development
- Zygote undergoes rapid cell division and differentiation.
- This transforms it into a multicellular embryo and then a fetus.
- Cell specialization creates tissues, organs, and organ systems.
- Fetal development involves organ growth and structural refinements leading to full-term viability.
Birth
- Childbirth (parturition) is the fetus delivery process.
- Hormones, including oxytocin, stimulate contractions.
- In placental mammals, placenta facilitates nutrient exchange and hormone production.
Hormonal Regulation
- Gonadotropin-releasing hormone (GnRH) from hypothalamus triggers follicle-stimulating hormone (FSH) and luteinizing hormone (LH) release.
- FSH and LH from pituitary control sperm and ova production, ovulation, and menstruation.
- Estrogen, progesterone, and testosterone influence secondary sexual characteristics and regulate reproductive cycles.
- These hormones are crucial for homeostasis and reproductive functions.
Contraception
- Contraception methods prevent pregnancy.
- Various methods include hormonal, barrier, and surgical approaches.
- Social and cultural factors affect contraceptive choices.
Infertility
- Infertility is the inability to conceive after a year of unprotected intercourse.
- Infertility factors include issues with both male and female reproductive systems.
- Assisted reproductive technologies (ARTs), like IVF, aim to increase chances of conception.
Reproductive Health
- Reproductive health encompasses physical, mental, and social well-being.
- Reproductive health concerns are important to public and individual well-being.
- Preventative measures (vaccinations) and early detection improve reproductive health.
