The first two stages of LGV produce symptoms that are similar to the symptoms of many other diseases (including colitis, proctitis, proctocolitis, Crohn’s disease, and ulcerative colitis) as well as other STDs (such as syphilis, herpes, and chancroid). The second stage of LGV can also be confused with tuberculosis and plague, as well as cancers [...]

Two tests are commonly used to determine if the ELISA test results are accurately positive. The first is the recombinant immunoblot assay (RIBA), which also looks for antibody to the virus but is more sensitive than the ELISA (enzyme-linked immunosorbent assay). The second is the polymerase chain reaction (PCR) test, which looks for the genetic [...]

Cytomegalovirus is present in the genital secretions of both men and women who are infected. Other body fluids that have been found to have sufficient quantity of virus for transmission are blood, saliva, urine, and breast milk. Thus cytomegalovirus can be transmitted through oral, anal, and genital sexual contact, through kissing, through blood exchange (such [...]

Some scientists have been impressed by initial reports of this test’s success: In one recent study, researchers obtained blood from radical prostatectomy patients before they underwent surgery. They compared the frequency of a positive PCR test for PSA (which means cells in the blood were able to secrete PSA) to a man’s pathologic stage of [...]

Pregnancy. Sometimes spotting occurs early in pregnancy. Usually there will also be signs of pregnancy, such as a missed period, breast tenderness, or morning nausea. Spotting may occur even if the pregnancy is proceeding without complications, but it can also signal a problem with the pregnancy, either a “threatened abortion” (meaning that a miscarriage may [...]

The 1973 U.S. Supreme Court decision Roe v. Wade found that abortion is a matter of privacy, just like contraception. However, the judges considered each of the three stages, or trimesters, of pregnancy differently. A state may not pass any laws to interfere with a woman’s right to abortion during the first three months of [...]

Chlamydia (cla-MIH-dee-ah) is a microscopic parasite that can cause sterility in women and men. In women, chlamydia infects the cervix and can spread to the urethra, fallopian tubes, and ovaries. It can cause bladder infections and serious pelvic inflammatory disease (PID), ectopic pregnancy, and sterility. In men, chlamydia infects the urethra and may spread to [...]

Attitudes toward marriage and sex became somewhat more positive during the Reformation, even though women, their bodies, minds, and functions continued to be denigrated. Martin Luther in his Table Talk (Luther) said that women had narrow chests and broad hips because they were destined to “remain at home, sit still, keep house, and bear and [...]

There are societies, excluding the United States, in which no effort or only limited effort is made to conceal parental sexual encounters from children. Among the Melanesians to whom a certain amount of parental privacy is considered desirable, if a child becomes too curious and bold, it is told to mind its own business and [...]

At birth and perhaps even before, the sensor) motor, and neurologic systems are sufficiently mature to permit genitopelvic functioning. The male infant may be born with a penile erection and erections are observed in the majority of them in the early weeks of life. The parallel phenomenon, vaginal lubrication in the female infant, is more [...]
