What is Abortion procedure The end of a PREGNANCY before the FETUS is viable (capable of independent life). Abortion may occur spontaneously (commonly called miscarriage) or be induced to end a pregnancy. In the United States, federal law mandates the availability of induced abortion, and state laws regulate the definition of viability as it applies to induced abortion. The range of legal viability is 20 weeks to 24 weeks of gestational age. The clinical
What is Adenomyosis A condition in which the cells that make up the endometrium (the lining of the UTERUS) grow into the wall of the uterus (myometrium), forming benign (noncancerous) tumors that appear as thickenings or masses contained within the uterine wall.

Researchers do not know what triggers the physiologic events that take place to initiate reproductive and sexual maturity. However, these events result in the development of SECONDARY SEXUAL CHARACTERISTICS, sex drive and interest, and the ability to produce new life. Male FERTILITY extends from puberty to the end of
What is Alpha fetoprotein (AFP) A protein the LIVER produces. In PREGNANCY the amount of AFP in the woman’s BLOOD circulation increases, reflecting the activity of the FETUS’s liver as it develops and becomes functional. A blood test measures AFP in the woman’s blood circulation early in the second trimester, between 15 and 22 weeks of pregnancy.

Obstetricians use amniocentesis, typically performed during the second trimester of PREGNANCY, to help diagnose GENETIC DISORDERS and health conditions of the developing fetus such as DOWN SYNDROME or SPINA BIFIDA and other NEURAL TUBE DEFECTS.
What is Amniotic Fluid Amniotic Fluid - The liquid that surrounds the developing FETUS within the amniotic sac, a membranous structure that forms inside the UTERUS in PREGNANCY. The amnion, the inner membrane of the amniotic sac, begins producing amniotic fluid at about two weeks of gestation. The amniotic fluid, which is mostly water, cushions the fetus against changes in temperature as well as jarring and bumps from outside the womb. The composition of
