Lesson Flashcards: Sperm Production Biology

A stage in adolescence when humans reach sexual maturity and are capable of reproduction

Sex hormones released from the testes and ovaries, and in small volumes from the adrenal glands, to control the development of male sex organs, secondary sexual characteristics, and arousal in both males and females

A tissue that functions as lining and protection for body and organ surfaces

Male gonads that produce sperm and male sex hormones

A cell that has two complete sets of chromosomes (2n)

The cells that are located in the testes between the seminiferous tubules and secrete testosterone

A duct in the male reproductive system that transports sperm cells from the epididymis to the urethra

A gonadotropin hormone released by the pituitary gland that acts in synergy with LH and has a role in stimulating puberty and gamete production in the gonads

A hormone that is secreted from the anterior pituitary gland in the brain and stimulates the production of testosterone from the Leydig cells in the testes

A duct through which urine and semen are expelled out of the male body

A diploid cell formed during the second stage of spermatogenesis via mitotic division and differentiation of some types of spermatogonia

Undifferentiated diploid (2n) stem cells existing in the testes and ovaries that differentiate to form haploid (n) gametes

A sex hormone, primarily produced by the testes, that stimulates the growth of sex organs and the development of secondary sexual characteristics in males

A structure that is used to transport mature sperm cells to the epididymis

A long coiled tube that stores sperm and transports them from the testes into the vas deferens
