Study Notes

Secondary Sex Characteristics

These characteristics are not directly involved in reproduction.
They contribute to sexual dimorphism, the differences in appearance between males and females.
They are influenced by hormonal changes during puberty, particularly testosterone in males and estrogen in females.
Examples include body hair, voice changes, muscle mass, breast development, facial features, hip and pelvic shape, fat distribution, and skin changes.

Human Reproductive System

A complex system responsible for sexual reproduction.
It produces, nurtures, and transports reproductive cells (gametes) and facilitates fertilization and embryonic development.

Male Reproductive System

Produces, transports, and delivers sperm.
Facilitates the fertilization of an egg.

Parts of the Male Reproductive System

Testes: produce sperm and testosterone.
Epididymis: matures, stores, and moves sperm out of the body.
Vas Deferens: carries mature sperm from the epididymis to the ejaculatory ducts.
Ejaculatory Ducts: combine sperm with seminal fluid and transport it to the urethra.
Urethra: passage for urine and semen out of the body.
Seminal Vesicles: produce fluid that nourishes sperm and neutralizes the acidic environment of the female reproductive tract.
Prostate Gland: surrounds the urethra, contributes fluid to semen, contains enzymes that support sperm.
Bulbourethral Glands (Cowper's Glands): secrete lubricating fluid for the urethra during ejaculation.
Penis: external organ, erectile tissue engorges with blood during arousal, delivers sperm and urine.

Female Reproductive System

Produces and nurtures female gametes (eggs).
Supports fetal development.

Parts of the Female Reproductive System

Ovaries: produce eggs (ova) and hormones like estrogen and progesterone.
Fallopian Tubes (Oviducts): pathway for eggs from ovaries to the uterus, where fertilization usually occurs.
Uterus (Womb): hollow, muscular organ where a fertilized egg implants and develops.
Cervix: lower end of the uterus, protects against foreign substances, produces mucus to affect sperm transport.
Vagina: muscular canal connecting the cervix to the external genitalia, passage for menstrual flow and the penis, also the birth canal.
External Genitalia (Vulva): includes the mons pubis, labia majora, labia minora, clitoris, and vaginal opening.

Menstrual Cycle

Cyclical changes in the female reproductive system.
Includes egg release (ovulation), uterine lining changes, and hormonal fluctuations.
Essential for fertility and reproductive health.
