Mons pubis

skin-covered pad of fat over symphysis pubis in females


muscle layer of uterus


female gonads; produce ovum


female sex cells


male genitalia; organ enabling sperm to enter vagina

Prostate gland

secretes fluid into semen that helps sperm maintain activity and mobility


male sex cells


male gonads; produce sperm


fertilized ovum after sperm enters


hormone stimulating development of an egg in females

Asexual reproduction

Labium minora

"small lips" of the vulva of the vagina

Labium majora

Bartholin's gland

secretes mucus-like lubricating fluid in the vagina; located on either side of vaginal outlet

Fallopian tubes

conduct the ovum from the ovary to the uterus


hollow, muscular organ where a fertilized egg implants and grows

Glans penis

sensitive head portion of the penis

Menstrual cycle

cyclical changes in the uterine lining


passageway for elimination of urine; in males also acts as genital duct that carries sperm to exterior
