Summarizing Human Reproductive Anatomy and Gametogenesis


As animals became more complex, specific organs and organ systems developed to support specific functions for the organism. The reproductive structures that evolved in land animals allow males and females to mate, fertilize internally, and support the growth and development of offspring. Processes developed to produce reproductive cells that had exactly half the number of chromosomes of each parent so that new combinations would have the appropriate amount of genetic material. Gametogenesis, the production of sperm (spermatogenesis) and eggs (oogenesis), takes place through the process of meiosis.


bulbourethral gland

secretion that cleanses the urethra prior to ejaculation


sensory structure in females; stimulated during sexual arousal

labia majora

large folds of tissue covering the inguinal area

labia minora

smaller folds of tissue within the labia majora


process of producing haploid eggs


(also, fallopian tube) muscular tube connecting the uterus with the ovary area


male reproductive structure for urine elimination and copulation

prostate gland

structure that is a mixture of smooth muscle and glandular material and that contributes to semen


sac containing testes; exterior to the body


fluid mixture of sperm and supporting materials

seminal vesicle

secretory accessory gland in males; contributes to semen

seminiferous tubule

site of sperm production in testes


process of producing haploid sperm


pair of reproductive organs in males


environment for developing embryo and fetus


muscular tube for the passage of menstrual flow, copulation, and birth of offspring
