John McLean Morris
John McLean Morris (September 1, 1914 – April 8, 1993) was an American gynecologist, surgeon and researcher. Morris was born on September 1, 1914, in Kuling, China, where his father, DuBois S. Morris, was a Presbyterian missionary. He later recalled being affected by the widespread infanticide of baby girls, saying "Unwanted female infants were disposed of by throwing them through a small hole in one of the dozens of stone huts erected for the purpose around the countryside." The family returned to the United States where Morris attended the preparatory Hotchkiss School in Lakeville, Connecticut. Morris majored in biology at Princeton University where he was a member of the Cap and Gown Club and the managing editor of ''The Daily Princetonian''. He graduated in 1936 and went on to Harvard Medical School, graduating in 1940. During World War II, Morris served in the Medical Corps of the Navy, serving as a lieutenant commander for four years. He married Marjorie Austin Morris o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Androgen Insensitivity Syndrome
Androgen insensitivity syndrome (AIS) is a difference in sex development involving hormonal resistance due to androgen receptor dysfunction. It affects 1 in 20,000 to 64,000 XY ( karyotypically male) births. The condition results in the partial or complete inability of cells to respond to androgens. This unresponsiveness can impair or prevent the development of male genitals, as well as impairing or preventing the development of male secondary sexual characteristics at puberty. It does not significantly impair female genital or sexual development. The insensitivity to androgens is therefore clinically significant only when it occurs in genetic males, (i.e. individuals with a Y-chromosome, or more specifically, an SRY gene). Clinical phenotypes in these individuals range from a typical male habitus with mild spermatogenic defect or reduced secondary terminal hair, to a full female habitus, despite the presence of a Y-chromosome. AIS is divided into three categories that are d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prostate Cancer
Prostate cancer is cancer of the prostate. Prostate cancer is the second most common cancerous tumor worldwide and is the fifth leading cause of cancer-related mortality among men. The prostate is a gland in the male reproductive system that surrounds the urethra just below the bladder. It is located in the hypogastric region of the abdomen. To give an idea of where it is located, the bladder is superior to the prostate gland as shown in the image The rectum is posterior in perspective to the prostate gland and the ischial tuberosity of the pelvic bone is inferior. Only those who have male reproductive organs are able to get prostate cancer. Most prostate cancers are slow growing. Cancerous cells may spread to other areas of the body, particularly the bones and lymph nodes. It may initially cause no symptoms. In later stages, symptoms include pain or difficulty urinating, blood in the urine, or pain in the pelvis or back. Benign prostatic hyperplasia may produce similar symptoms ...

Intrauterine Device
An intrauterine device (IUD), also known as intrauterine contraceptive device (IUCD or ICD) or coil, is a small, often T-shaped birth control device that is inserted into the uterus to prevent pregnancy. IUDs are one form of long-acting reversible birth control (LARC). One study found that female family planning providers choose LARC methods more often (41.7%) than the general public (12.1%). Among birth control methods, IUDs, along with other contraceptive implants, result in the greatest satisfaction among users. IUDs are safe and effective in adolescents as well as those who have not previously had children. Once an IUD is removed, even after long-term use, fertility returns to normal rapidly. Copper devices have a failure rate of about 0.8% while hormonal ( levonorgestrel) devices fail about 0.2% of the time within the first year of use. In comparison, male sterilization and male condoms have a failure rate of about 0.15% and 15%, respectively. Copper IUDs can also be u ...

Diethylstilbestrol
Diethylstilbestrol (DES), also known as stilbestrol or stilboestrol, is a nonsteroidal estrogen medication, which is presently rarely used. In the past, it was widely used for a variety of indications, including pregnancy support for those with a history of recurrent miscarriage, hormone therapy for menopausal symptoms and estrogen deficiency, treatment of prostate cancer and breast cancer, and other uses. By 2007, it was only used in the treatment of prostate cancer and breast cancer. In 2011, Hoover and colleagues reported on adverse health outcomes linked to DES including infertility, miscarriage, ectopic pregnancy, preeclampsia, preterm birth, stillbirth, infant death, menopause prior to age 45, breast cancer, cervical cancer, and vaginal cancer. While most commonly taken by mouth, DES was available for use by other routes as well, for instance, vaginal, topical, and by injection. DES is an estrogen, or an agonist of the estrogen receptors, the biological target of estroge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morning-after Contraception
Emergency contraception (EC) is a birth control measure, used after sexual intercourse to prevent pregnancy. There are different forms of EC. Emergency contraceptive pills (ECPs), sometimes simply referred to as emergency contraceptives (ECs), or the morning-after pill, are medications intended to disrupt or delay ovulation or fertilization, which are necessary for pregnancy. p. 121: Intrauterine devices (IUDs)usually used as a primary contraceptive methodare sometimes used as the most effective form of emergency contraception. However, the use of IUDs for emergency contraception is relatively rare. Definition Emergency contraception is a birth control measure taken to reduce the risk of pregnancy following unprotected sexual intercourse or when other regular contraceptive measures have not worked properly or have not been used correctly. It is intended to be used occasionally and is not the same as medical abortion. Emergency contraception is offered to women who do not wish t ...

Gertrude Van Wagenen
Gertrude L. Van Wagenen (1893 – February 8, 1978) was an American biologist. She was also a collector of anatomical illustrations and models. Early life Gertrude L. Van Wagenen was the daughter of Anthony Van Wagenen (1852–1937), a judge and lawyer in Sioux City, Iowa, and his wife Gertrude (''née'' Louis). She completed undergraduate studies at Iowa State University in 1913, where she majored in zoology and was a member of the Beta Zeta chapter of the Kappa Kappa Gamma sorority. For a few years after graduating, she taught in Ottumwa, Iowa, and endured a case of scarlet fever, with the quarantine it required. In 1918, she collected corals, anemones, and medusae as part of the Barbados-Antigua Expedition, a group of University of Iowa graduate students and faculty studying the natural history of those islands. Her doctoral dissertation at the University of Iowa was titled ''The Coral Mussa Fragilis and Its Development''. Research Van Wagenen was associate professor ...

Estrogen
Estrogen or oestrogen is a category of sex hormone responsible for the development and regulation of the female reproductive system and secondary sex characteristics. There are three major endogenous estrogens that have estrogenic hormonal activity: estrone (E1), estradiol (E2), and estriol (E3). Estradiol, an estrane, is the most potent and prevalent. Another estrogen called estetrol (E4) is produced only during pregnancy. Estrogens are synthesized in all vertebrates and some insects. Their presence in both vertebrates and insects suggests that estrogenic sex hormones have an ancient evolutionary history. Quantitatively, estrogens circulate at lower levels than androgens in both men and women. While estrogen levels are significantly lower in males than in females, estrogens nevertheless have important physiological roles in males. Like all steroid hormones, estrogens readily diffuse across the cell membrane. Once inside the cell, they bind to and activate estrogen receptors (E ...

Testosterone
Testosterone is the primary sex hormone and anabolic steroid in males. In humans, testosterone plays a key role in the development of Male reproductive system, male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of androgenic hair, body hair. In addition, testosterone in both sexes is involved in health and well-being, including moods, behaviour, and in the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty and bone loss. Testosterone is a steroid from the androstane class containing a ketone and a hydroxyl group at positions three and seventeen respectively. It is Biosynthesis, biosynthesized in several steps from cholesterol and is converted in the liver to inactive metabolites. It exerts its action through binding to and activation of the androgen receptor. In humans and most other vertebrates, testost ...
