Human Sexuality – Chapter 4&5 Menopause: • Menopause: permanent cessation of menstruation o Climacteric – 15 years of slowing down • Symptoms vary – sweating, hot flashes, night sweats, interrupted sleeps • Hormone replacement therapy – this was thought we be a very effective way of getting rid of hot flashes. This is estrogen, and high levels of it increase the chance of breast cancer. The Breast: • Mammary glands produce milk – however the bigger the breast doesn’t mean you have more milk o Fatty tissues determines the size of ones breast • Secondary sex characteristic – breast are not the necessary part of reproduction • Cultural perceptions vary dramatically – in NA we have sexualized the breast to a great extent. In other countries like India, there are very strong cultural norms about women dressing properly, but breast-feeding a baby is normal there. • Breast cancer – very big risk in women. 1 in 9 women will experience breast cancer. o Risk factors – the more estrogen exposure you have, the more likely you are to get cancer. Things that increase this is early menstruation or late menopause. First child after 30, obesity, heavy drinking, also a genetic predisposition gives an 85% of chance of breast cancer. More likely in the 40’s and 50’s o Detection and treatment – women are encouraged to look for lumps in your breast, but mammograms are better for detecting lumps before it’s to late. Often women 50 and over they are mandatory every 2 years. A lump doesn’t always mean breast cancer, it could be a cist or thyroid problem. External Male Sexual Anatomy: • The penis – male organ of sexual intercourse. Sperm is release through the penis and its very sensitive o Glans – like the clitoris, its at the head of the penis and has a lot of nerve endings. So sensitive that heavy stimulation could be painful to the glans. o Shaft – the body of the penis o Root – where the penis is attached into the body o There is no bone in the penis, but have areas that engorge with blood causing it to become erect o Corpus carvernosa – side by side on the penis that are spongy tissue that becomes filled with blood during sexual arousal o Corpus spongisum – smaller then the carvernosa and is at the bottom of the penis • Size issues – many men are often insecure about their penis size • Foreskin – it covers the penis o Circumcision – very common procedure in Canada. In curtain cultures it is done as well. UTI are more likely among men that haven’t been circumcised as well as HIV, infections and HPV. o In the past most baby boys were circumcised • The scrotum – a sac or pouch with two chambers o Cremaster muscle – this hold the sac closer to the body in cold temperature. This is important for the health of the sperm. Hot and cold temperatures cause this to happen o Spermatic cord – each testicle is suspends by a spermatic cord, this contains • The testes – these release testosterone o Secrete male hormones o Produce perm – just like the ovaries produce eggs o Seminiferous tubules  Site of sperm production o Epididymis – sperm masturation Internal Male Sexual Anatomy: • The vas deferens – thing tube that carries sperm to the penis and its found
