Study Notes
Male Reproductive System
- The male reproductive system includes the testes, which produce testosterone and sperm, and accessory structures that nurture and conduct sperm out of the body.
- Testosterone and sperm are produced continuously from puberty until death.
- The testes are located in the scrotum, a pouch outside the abdominal cavity, where the cooler temperature promotes sperm development.
- Each testis is filled with coiled seminiferous tubules, where sperm are produced, and interstitial cells that synthesize testosterone.
- Spermatogenesis occurs in the seminiferous tubules, where stem cells called spermatogonia divide and differentiate into haploid sperm.
Spermatogenesis
- A spermatogonium divides into two daughter cells: one remains a spermatogonium, and the other becomes a primary spermatocyte.
- The primary spermatocyte undergoes meiotic cell division, producing two haploid secondary spermatocytes.
- Each secondary spermatocyte undergoes meiosis II, producing two spermatids.
- Spermatids differentiate into sperm without further cell division.
- The developing sperm migrate to the central cavity of the seminiferous tubule, where they are released.
Hormonal Control of Spermatogenesis
- Spermatogenesis is stimulated by GnRH from the hypothalamus, which triggers the release of LH and FSH from the anterior pituitary.
- LH stimulates interstitial cells to produce testosterone, and FSH stimulates Sertoli cells to promote spermatogenesis.
- The combination of testosterone and FSH inhibits FSH release, regulating spermatogenesis through negative feedback.
Female Reproductive System
- The female reproductive system includes the ovaries, which produce eggs, estrogen, and progesterone, and accessory structures that accept sperm, conduct eggs to the uterine tube, and nourish the developing embryo.
Oogenesis
- An oogonium enlarges to form a primary oocyte, which undergoes meiosis I, producing a secondary oocyte and a small polar body.
- At meiosis II, the secondary oocyte produces an egg, and a second polar body discards the remaining chromosomes.
- Meiosis II does not occur unless a sperm penetrates the egg.
Hormonal Control of Menstrual Cycle
- The menstrual cycle consists of two related cycles: the ovarian cycle and the uterine cycle.
- The hypothalamus secretes GnRH, which stimulates the anterior pituitary to release LH and FSH.
- FSH stimulates follicle development, and the follicle cells release estrogen, which stimulates a surge of LH, causing ovulation and the release of the secondary oocyte.
- The corpus luteum, formed from the remaining follicle cells, secretes estrogen and progesterone, which inhibit further release of GnRH, LH, and FSH, preventing the development of more follicles.
Male Reproductive System
- The male reproductive system includes the testes, glands, and tubes that produce and transport sperm and testosterone.
- The testes hang beneath the abdominal cavity in the scrotum, which keeps them 1-6°F cooler than the core body temperature, promoting sperm development.
- Each testis contains coiled, hollow seminiferous tubules where sperm are produced, and interstitial cells that synthesize testosterone.
- Spermatogonia, stem cells in the seminiferous tubules, give rise to sperm through mitotic cell division.
- Sertoli cells nourish and regulate the growth of developing sperm.
Spermatogenesis
- A spermatogonium divides into two daughter cells: one remains a spermatogonium, while the other becomes a primary spermatocyte, which undergoes meiotic cell division to produce haploid sperm.

- Spermatids differentiate into sperm without further cell division.
- The developing sperm migrate to the central cavity of the seminiferous tubule, where they are released.
Hormonal Control of Spermatogenesis
- GnRH from the hypothalamus stimulates the anterior pituitary to release LH and FSH, which regulate spermatogenesis.
- LH stimulates interstitial cells to produce testosterone, which, along with FSH, promotes spermatogenesis.
- FSH-stimulated Sertoli cells secrete inhibin, which inhibits FSH release.
- Testosterone inhibits the release of GnRH, LH, and FSH, maintaining a negative feedback loop to regulate sperm production.
Female Reproductive System
- The female reproductive system includes the ovaries and structures that accept sperm, conduct eggs, and nourish the developing embryo.
- The ovary produces eggs, estrogen, and progesterone during the menstrual cycle.
Oogenesis
- An oogonium enlarges to form a primary oocyte, which undergoes meiosis I to produce a secondary oocyte and a polar body.
- At meiosis II, almost all the cytoplasm of the secondary oocyte is included in the egg, and a second small polar body discards the remaining chromosomes.
- The polar bodies eventually degenerate, and meiosis II only occurs if a sperm penetrates the egg.
Menstrual Cycle
- Follicle development and ovulation are governed by interactions among hormones produced by the hypothalamus, anterior pituitary, and ovary during the menstrual cycle.
- GnRH from the hypothalamus stimulates the anterior pituitary to release LH and FSH, which stimulate follicle development and estrogen production.
- Estrogen stimulates a surge of LH, causing ovulation and the release of a secondary oocyte.
- The secondary oocyte will not undergo meiosis II unless it is fertilized.

- The ovary produces eggs, estrogen, and progesterone during the menstrual cycle.
Oogenesis
- An oogonium enlarges to form a primary oocyte, which undergoes meiosis I to produce a secondary oocyte and a polar body.
- At meiosis II, almost all the cytoplasm of the secondary oocyte is included in the egg, and a second small polar body discards the remaining chromosomes.
- The polar bodies eventually degenerate, and meiosis II only occurs if a sperm penetrates the egg.
Menstrual Cycle
- Follicle development and ovulation are governed by interactions among hormones produced by the hypothalamus, anterior pituitary, and ovary during the menstrual cycle.
- GnRH from the hypothalamus stimulates the anterior pituitary to release LH and FSH, which stimulate follicle development and estrogen production.
- Estrogen stimulates a surge of LH, causing ovulation and the release of a secondary oocyte.
- The secondary oocyte will not undergo meiosis II unless it is fertilized.
Male Reproductive System
- The male reproductive system includes the testes, glands, and tubes that produce and transport sperm and testosterone.
- The testes hang beneath the abdominal cavity in the scrotum, which keeps them 1-6°F cooler than the core body temperature, promoting sperm development.
- Each testis contains coiled, hollow seminiferous tubules where sperm are produced, and interstitial cells that synthesize testosterone.
- Spermatogonia, stem cells in the seminiferous tubules, give rise to sperm through mitotic cell division.
- Sertoli cells nourish and regulate the growth of developing sperm.
Spermatogenesis
- A spermatogonium divides into two daughter cells: one remains a spermatogonium, while the other becomes a primary spermatocyte, which undergoes meiotic cell division to produce haploid sperm.
- Primary spermatocytes give rise to two secondary spermatocytes through meiosis I, and each secondary spermatocyte undergoes meiosis II to produce two spermatids.
- Spermatids differentiate into sperm without further cell division.
- The developing sperm migrate to the central cavity of the seminiferous tubule, where they are released.
Hormonal Control of Spermatogenesis
- GnRH from the hypothalamus stimulates the anterior pituitary to release LH and FSH, which regulate spermatogenesis.
- LH stimulates interstitial cells to produce testosterone, which, along with FSH, promotes spermatogenesis.
- FSH-stimulated Sertoli cells secrete inhibin, which inhibits FSH release.
- Testosterone inhibits the release of GnRH, LH, and FSH, maintaining a negative feedback loop to regulate sperm production.
Female Reproductive System
- The female reproductive system includes the ovaries and structures that accept sperm, conduct eggs, and nourish the developing embryo.
- The ovary produces eggs, estrogen, and progesterone during the menstrual cycle.

- An oogonium enlarges to form a primary oocyte, which undergoes meiosis I to produce a secondary oocyte and a polar body.
