Male and female reproductive systems are complex and fascinating. The male system includes external parts like the penis and scrotum , and internal organs like testicles and prostate . These work together to produce and deliver sperm .
The female system has external parts like the labia and clitoris , and internal organs including the uterus and ovaries . This intricate system enables egg production, fertilization, and fetal development during pregnancy.

Penis functions as both reproductive and urinary organ
Consists of shaft and glans (head)
Contains erectile tissue that fills with blood during arousal
Urethra runs through center for urine and semen passage
Scrotum houses and protects testicles
Sac of skin located below penis
Regulates temperature of testicles for optimal sperm production
Foreskin covers glans of penis in uncircumcised males
Protects sensitive glans and keeps it moist
Can be retracted during sexual activity or cleaning
Internal Male Reproductive Organs
Testicles produce sperm and testosterone
Located within scrotum
Contain seminiferous tubules where sperm develop
Leydig cells produce testosterone
Vas deferens transports sperm from testicles
Long, muscular tube
Connects epididymis to urethra
Contracts during ejaculation to propel sperm
Prostate gland produces components of semen
Walnut-sized gland located below bladder
Surrounds urethra
Secretes alkaline fluid to protect sperm in acidic vaginal environment
Female Reproductive Anatomy
External Female Reproductive Organs
Labia protect vaginal opening
Consist of labia majora (outer lips) and labia minora (inner lips)
Vary in size and appearance among individuals
Clitoris serves as primary source of sexual pleasure
Located at top of vulva where labia meet
Contains thousands of nerve endings
Has internal structure extending into body
Bartholin's glands produce lubricating fluid
Located on either side of vaginal opening
Secrete mucus during sexual arousal
Help reduce friction during intercourse
Internal Female Reproductive Organs
Vagina connects external genitalia to uterus
Muscular, elastic canal
Allows for penetration during intercourse
Serves as birth canal during childbirth
Cervix forms lower part of uterus
Narrow passage connecting vagina to uterus
Produces cervical mucus that changes throughout menstrual cycle
Dilates during childbirth to allow passage of baby
Uterus houses developing fetus during pregnancy
Pear-shaped muscular organ
Inner lining (endometrium ) thickens and sheds during menstrual cycle
Expands significantly during pregnancy
Fallopian tubes transport eggs from ovaries to uterus
Pair of narrow tubes extending from uterus
Site of fertilization if sperm meets egg
Lined with cilia to help move egg and embryo
Ovaries produce eggs and hormones
Almond-shaped organs located on either side of uterus
Contain follicles housing immature eggs
Release mature egg during ovulation
Produce estrogen and progesterone
