Class notes:
Puberty in Males
Primary sex characteristics- sex characteristics present at birth (penis)
Secondary sex characteristics- sex characteristics that appear during puberty that gives the male the ability to reproduce. The hormone production of testosterone in the male testes causes this, as well as other changes, including (enlargement of the testes, pubic hair, armpit hair, lower voice, growth spurt, muscle growth, acne, nocturnal emissions, ejaculation, facial hair, chest hair, etc.)

Male reproductive system
Testosterone- hormone that is responsible for sperm production in males.
Testes- Where sperm is produced (beginning at puberty).
Scrotum- Thin layer of skin that holds the testes. Protects the sperm from extreme temperatures.
Penis- Organ through which semen and urine leave the male’s body.
Urethra- Tube down the center of the penis that carries semen and urine out of the body.
Epididymis- located behind each testicle. This is where the sperm mature and gain the ability to move.
Vas Deferens- tube sperm travels through as it leaves the epidydimis and heads toward the urethra. Passes through a series of glands on its way out.
Prostate Gland, Seminal vesicles- series of glands sperm passes through before it is ejaculated from the penis. These glands secrete fluids (seminal fluid) that mix with the sperm.
Seminal fluid- These fluids nourish the sperm and will lubricate the woman’s vagina to help the sperm as they travel through the woman’s reproductive system. Seminal fluid may also include any bacteria or viruses that will cause STI’s.
Semen- mixture of sperm and seminal fluid. This is what is ejaculated from the man’s penis.
Sperm- male sex cell that holds the males DNA. Approximately 1000 sperm are produced in each testicle every second, over 250 million sperm are present in 1 tablespoon of semen or are ejaculated at once.
Erection- hardening of the penis, caused by an increase in blood flow to the penis.
Ejaculation- forceful exiting of sperm from the penis.
