Secondary Sex Characteristics Males Low pitch voice, facial/body hair, muscular development Females Increase breast and hip size, body/pubic hair
Gonads The reproductive organs (sex organs) in a male (testes) or a female (ovaries). Developed at 8 weeks of fetal life.
Puberty The period of sexual maturation. Sequence of events leading to the development of the secondary sexual characteristics and fertility. Age of onset is 10-16 years old with the hypothalamus, pituitary glands and gonads.
Hypothalamus Control center of brain which signals pituitary gland with GnRH (gonadotropin-releasing hormone). Initiates our fertility capability.
Pituitary Gland In response to the hypothalamus message (GnRH) the pituitary gland releases gonadotropins (FSH and LH). These gonadotropins are responsible for stimulating the gonads to release sex hormones. For females these sex hormones are estrogen/progesterone and for males, testosterone.
II. Reproductive System The male and female gonads, associated ducts and glands, and external genitalia that function in the procreation of offspring. In women these include the ovaries, fallopian tubes, uterus, vagina, clitoris, and vulva. In men they include the testes, epididymis, vas deferens, seminal vesicles, ejaculatory duct, prostate and penis.
Primary syphilis – appearance of small painless red pustule on skin or mucous membrane 10 – 90 days after exposure – lesion may appear anywhere on body where contact with pathogen occurred – most often the anogenital region
This painless red pustule quickly erodes forming a painless, bloodless ulcer, called a chancre, exuding fluid filled with spirochetes – heals spontaneously within 10-40 days.
The secondary stage – occurs 2 months later – spirochetes have increased in number and spread throughout the body
