Female sex hormones
Gonadotropin-releasing hormone: GnRH, released by hypothalamus in the brain to stimulate anterior pituitary gland to release LH and FSH
Follicle stimulating hormone; FSH, stimulates the development and maturation of primary follicle in to secondary follicle. This stimulates ovaries to start maturation.
Luteinizing hormone: LH spike of hormone will trigger ovulation of the most mature follicle (only one).
Inhibin: decreases the release of FSH by anterior pituitary gland. Every month only one egg will be released.
Estrogen: primary female sex hormone released by the follicles. Low levels cause the release of FSH. High levels cause a release of LH and GRH. Thickening of the uterine wall. Causes secondary sex characteristics.

Sexually transmitted diseases : infections caused by sexual contact causes by bacteria, parasites, or viruses.

Male sex hormones
Luteinizing hormone LH; Stimulates seminiferous tubules to secrete testosterone, production and maturation.
Follicle stimulating hormone; At puberty stimulates sertoli cells for sperm production and maturation.
Gonadotropin releasing hormone; released by hypothalamus in brain to stimulate anterior pituitary gland to release LH and FSH. Its triggered by low levels of testosterone and controlled by negative feedback.
Testosterone; Stimulates reproductive organ development and sex drive. Causes secondary sex characteristics depending of voice, increased hair growth, enlargement of skeletal muscles, thickining bones.
