Study Notes
Overview of Human Reproduction
Reproductive System
- The human reproductive system consists of:
- Male reproductive system: testes, epididymis, vas deferens, prostate gland, urethra, and penis
- Female reproductive system: ovaries, fallopian tubes, uterus, cervix, and vagina
Male Reproductive System
Sperm Production
- Sperm cells are produced in the testes through a process called spermatogenesis
- Sperm cells are matured in the epididymis
- On average, a male produces 1,000-2,000 sperm per second
Sperm Structure
- Head: contains genetic material (DNA)
- Neck: connects the head to the tail
- Tail: propels the sperm forward
Female Reproductive System
Oogenesis
- Egg cells are produced in the ovaries through a process called oogenesis
- Oogenesis occurs in a series of stages, including:
- Oogonia formation
- Primary oocyte formation
- Secondary oocyte formation
Menstrual Cycle
- The menstrual cycle is a monthly process that prepares the uterus for a potential pregnancy
- The cycle consists of:
- Follicular phase: estrogen levels increase, causing the uterine lining to thicken
- Ovulation: release of an egg from the ovary
- Luteal phase: progesterone levels increase, preparing the uterus for implantation
- Menstruation: shedding of the uterine lining if pregnancy does not occur
Fertilization and Implantation
Fertilization
- Fertilization occurs when a sperm cell penetrates the outer layer of the egg cell
- The resulting cell is called a zygote
Implantation
- The zygote travels through the fallopian tube and into the uterus
- Implantation occurs when the zygote attaches to the uterine lining
Pregnancy and Development
Embryonic Development
- The zygote undergoes several stages of development, including:
- Morula stage
- Blastula stage
- Gastrula stage
- Organogenesis occurs during weeks 3-8 of pregnancy
Fetal Development
- The embryo is called a fetus after 8 weeks of pregnancy
- Fetal development is characterized by rapid growth and maturation of organs and systems

Reproductive System
- The human reproductive system consists of two parts: male and female reproductive systems.
Male Reproductive System
- The male reproductive system includes: testes, epididymis, vas deferens, prostate gland, urethra, and penis.
- Sperm cells are produced in the testes through a process called spermatogenesis.
- On average, a male produces 1,000-2,000 sperm per second.
- Sperm cells are matured in the epididymis.
- A sperm cell consists of:
- Head: contains genetic material (DNA)
- Neck: connects the head to the tail
- Tail: propels the sperm forward
Female Reproductive System
- The female reproductive system includes: ovaries, fallopian tubes, uterus, cervix, and vagina.
- Egg cells are produced in the ovaries through a process called oogenesis.
- Oogenesis occurs in a series of stages, including:
- Oogonia formation
- Primary oocyte formation
- Secondary oocyte formation
- The menstrual cycle is a monthly process that prepares the uterus for a potential pregnancy.

- Fetal development is characterized by rapid growth and maturation of organs and systems.
