Facts About youV. Genital DevelopmentVI. Adult Male GenitalsCurrent LectureI. Alfred Kinsey a. 1947 (Sex education)b. Taught how to prevent pregnancy (i.e., condoms)c. State legislature of Indian tried to have him fired for ruining the morals of children. The state threatened to remove all state funding if the school didn’t fire him. Agreement: he could only teach the class at a graduate level.II. Masters and Johnson (textbook)a. Research team at Washington University in Saint Louisb. Scientifically studied sexualityc. Sex lab (in vivo)III. Random Infoa. Penile ring to bleed the devil out when men got erections when sleepingb. Men and women overall took the same amount of time to orgasm during masturbation. Women were mostly stimulating their citreous.IV. Facts About Youa. 1 x 1011 stars in our galaxyb. 1 x 1011 neurons in your brainc. 1 x 1012 cells in your bodyi. 1 x 1014 atoms in a cell1. Every atom in on earth comes from an exploded stara. “you are a miraculous star and your genitals are miraculous”d. The largest cell in the body is the female egg (1/180 inch)These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.e. The smallest cell in the human body is the sperm cellf. 1750,000 sperm weight the same as a single eggg. every skin/sensory cell is capable of creating pain/pleasure  skin is the largest source of pleasure (stimulation)i. *the brain is also an acceptable answerV. Genital Developmenta. Prenatal developmenti. Both males and females start having vaginas until the 6th-7th week when males produce testosterone which causes external changes.ii. *Know equivalencies (every male part has a female part)1. penile shaft = inner lips2. head of the penis = citreous3. scrotal sac = outer lipsiii. genitals are pretty much completed by the end of the 1st trimesteriv. males produce MIS which inhibits the development of Mullerian system in males (fallopian tube development)VI. Adult Male Genitalsa. Testes housed in scrotal sac (2 of each)  1 sac with 2 chambersi. Held in place and can move up and down (depending on temperature) by spermatic cord. Closer to the body when it is cold outside.b. Testes producei. Seminiferous tubules – sperm production occurs here. They are inter wound around each other. ii. Cells in between tubules (sertoli) produces testosterone which travels through the blood systemc. Spermi. Have a tail for movementii. Mitochondria – the engines of the cell (convert star dust, aka food, into energy)iii. Genetics are stored in the headd. *Men are more genetically similar to their fathers and more like their fathers hormonallye. Epidermis (on top of skin)i. Sac of skin on top of testes that stores spermf. Vas deferens (tube)i. Carries sperm from epidermis to the seminal vesicle ii. Once sperm hits seminal vesicles it hits fluid  becomes semen and can swim. iii. Sugars give energy to mitochondria and
