BIOMEDICAL PERSPECTIVE IN GENDER AND SOCIETY ANATOMY AND PHYSIOLOGY OF REPRODUCTION  A Biological Female A person with XX chromosomes usually has female sex and reproductive organs, and is therefore usually assigned biologically female. A person with XY chromosomes usually has male sex and reproductive organs, and is therefore usually assigned biologically male.  PUBERTY The process of physical changes through which a child's body matures into an adult body capable of sexual reproduction and when the boy or girl becomes sexually mature. The menstrual cycle marks begin in females  Menstrual Phase The first stage of the menstrual cycle. This occurs if the ovum is not fertilized and does not implant itself into the uterine lining. And levels of the hormones estrogen and progesterone drop.  Proliferative Phase The proliferative phase lasts of a woman's cycle (usually 14-18 days in most woman). In proliferative phase, the lining of the tissue in the uterus. Proliferation means the cells are multiplying and spreading to build new tissue. Secretory Phase The third and final phase of the uterine cycle  More female characteristics greater proportion lower mortality rate at -generally shorter of body weight every age longer than man composed of fat projected lifespan than than men men THE BIOLOGICAL MALE  Male External Genitalia consist of ▸The male sexual anatomy is the following structures designed for the production and delivery of sperm for fertilization of 1. Prepuce - foreskin covering head of penis, the female's ovum. Puberty signals removed in male circumcision the final development of primary and accessory organs that support reproduction 2. Penis-glans (head), shaft, and root. The glans is particularly sensitive to stimulation. Running the length of the penis is the urethra surrounded by the spongy body and two cylindrical chambers known as the cavernous bodies. During arousal, these become engorged with blood, resulting in erection 3.Corona - rim of glans where it arises from shaft 4. Frenulum-thin strip of skin connecting glans and shaft on underside of penis; 5. Scrotum-sac that encloses the two compartments housing the testes 6. Urethral opening - found on head of penis this is the end of tube connected to bladder and used for urination. It is also tube to which internal structures deliver semen by which male ejaculates; and 7. Perineum - area of skin separating the genitalia from the anus, distance is greater in males than females. The male internal reproductive organs: 1. Testes-produce androgen, particularly large quantities of testosterone, which greatly influence male development and drive sexual motivation; also produce sperm cells in virtually unlimited quantity over the entire course of the lifespan 2. Vas deferens-travels from testicle toward urethra carrying sperm The male internal reproductive organs: 3. Seminal vesicles-two glands that produce alkaline fluid rich in fructose sugar, comprising some 70% of semen volume. Alkaline nature may stimulate sperm to start self-propulsion and sugar may provide sperm nutrients. Ducts carry fluid and connect with vas deferens forming ejaculatory ducts; 4. Ejaculatory ducts-connect vas deferens to urethra; The male internal reproductive organs: 5. Prostate- gland producing alkaline secretions that account for about 10% of semen volume. Alkaline nature may help counteract otherwise, acidic environment of urethra and vagina making them more hospitable for sperm. Fluid passes through a series of ducts along wall of urethra. 6. Urethra-tube within penis that carries sperm and semen the rest of the way  MALE CHARACTERISTICS -generally -proportionately -exposure to greater -single X chromosome taller and larger heart and levels of testosterone resulting in sex-linked greater lungs, presumably resulting in heavier conditions such as proportion of to handle greater body and facial hair, colorblindness and body weight blood Quid volume; but also increased hemophilia. composed of frequency and water degree of baldness, and  Male Hormones ▸The testosterone is the major male hormone produced mainly by the testes, but there are other glands called the adrenal glands that also produce some testosterone. In case a man has lost his testes, these glands would continue to produce testosterone to support the male physical appearance. Testosterone is responsible for the growth and development of a boy during adolescence and for the development of sperm and secondary sexual characteristics.  Growth of facial and body hair Here are some physical Deepening of the voice changes that take place in Growth of the genitals males during Increase in height and muscle mass puberty: Development of acne
