Reproductive System

The Male Reproductive System Testes Ducts Glands

External Genitalia: Testes, Scrotum, and Penis

Testes

Scrotum

Penis

Penis with prepuce

Penis without prepuce

Ducts Epididymis Vas Deferens Ejaculatory Duct Urethra

Epididymis

Vas Deferens

Ejaculatory Duct

Urethra

Glands Seminal Vesicles Prostate Gland Bulbourethral Glands (Cowper’s Glands)

Seminal Vesicles

Prostate Gland

Bulbourethral Glands (Cowper’s Glands) Pea-sized glands inferior to the prostate gland Produce a mucus

Seminal Fluid = Mixture of secretions from the seminal vesicles, prostate gland, and bulbourethral glands Semen = Sperm and seminal fluid secreted during ejaculation

The Female Reproductive System

Figure 24.11a

Ovaries

Fallopian Tubes

Uterus Figure 24.10

Uterine Wall

Vagina

External Genitalia and Female Perineum

Deep Structures of the External Genitalia and Female Perineum

Male Reproductive Hormones Gonadotropin Releasing Hormone (GnRH) Follicle Stimulating Hormone (FSH) Luteinizing Hormone (LH) Testosterone Inhibin Progestins (such as progesterone)

Male Reproductive Hormones

Female Reproductive Hormones Gonadotropin Releasing Hormone (GnRH) Follicle Stimulating Hormone (FSH) Luteinizing Hormone (LH) Estrogens Inhibin Progestins (such as progesterone)

Female Reproductive Hormones

The Ovarian Cycle Follicular Phase Luteal Phase

Ovarian and Uterine Cycles

The Ovarian Cycle

The Uterine Cycle Series of cyclic phases of the endometrium Phases coordinate with the ovarian cycle Controlled by FSH and LH Phases of uterine cycle Menses – days 1-7 Proliferative phase – days 8-14 Secretory phase – days 15-28

The Uterine Cycle

The Mammary Glands

Events Leading to Fertilization
