Improving contraceptive delivery by increasing on-site availability in physicians' offices and clinics of a range of contraceptive methods, including LARCs, might increase contraceptive use and reduce rates of unintended pregnancy. Although most women and men who undergo contraceptive sterilization do not regret having had the procedure, the permanence of the method is an important consideration, as regret has been documented in studies

in vitro fertilization Reproduction medicine A procedure that bypasses some causes of infertility, by removing eggs from the ovaries and fertilizing them ex vivo; the resulting early embryo is then transferred into the uterus via the cervix. IVF Fertilization of an egg outside the body of a female by the addition of sperm, as a means of producing a zygote.in vitro fertilization (IVF), a method of fertilizing human ova outside the body by collecting the mature ova and placing them in a dish with a sample of spermatozoa

Those offering assisted reproductive techniques are not always regulated by the government, and abuses have been reported, including lack of informed consent, unauthorized use of embryos, and failure to routinely screen donors for disease.The clinic should always provide the following information:The live-birth rate (not just pregnancy success rate) for other couples with similar infertility problems. It involves an open incision and may be done under general or spinal anesthesia in a hospital setting, although the patient can often go home the same day

Technical Issues In Reproductive Health

Following ovulation, the ruptured follicle is transformed into the corpus luteum, a glandular mass that continues to produce estrogen and high levels of progesterone. Female puberty generally occurs between the ages of 9-13, and results in ovulation and menstruation, which involve cyclic hormonal changes in estrogen and progesterone

The underlying stratum basale or basal layer is retained throughout the menstrual cycle and serves as the regenerative source of the stratum functionale. What layers must nutrients cross to get from maternal to fetal blood in early and late pregnancy? (FE5) Large quantities of an amorphous eosinophilic substance, fibrinoid WebScope , may also be deposited in the intervillus space in this older placenta

After the cancer has been removed, the physician may recommend the woman undergo chemotherapy (using a combination of drugs to kill any remaining cancer cells and shrink any tumors) or radiation therapy (using X rays or other high-energy rays to kill any remaining cancer cells and shrink any tumors) or a combination of both. The alkaline seminal fluid neutralizes the acid in the vagina, allowing sperm in the semen to exist and move in the vagina so fertilization may take place

The entrance for the laparoscope may be through the umbilicus, through a small incision in the lower abdominal wall, or through the posterior fornix of the vagina into the rectouterine pouch. The causes of breast cancer are not known, but women who are most susceptible are those who are over age 35, who have a family history of breast cancer, and who are nulliparous (never having given birth)

Male Reproductive System

Although circumcision is not medically necessary, parents who choose to have their children circumcised often do so based on religious beliefs, concerns about hygiene, or cultural or social reasons. The male genitals include: the testicles the duct system, which is made up of the epididymis and the vas deferens the accessory glands, which include the seminal vesicles and prostate gland the penis In a guy who's reached sexual maturity, the two testicles (pronounced: tes-tih-kulz), or testes (pronounced: tes-teez), produce and store millions of tiny sperm cells

Its cause is largely unknown.Changes to the uterus or cervixSperm may fail to reach the egg if scarring caused by surgery, blockage or inflammation, reduces access to the cervix. In most cases, problems are caused by a hormonal imbalance: the body may not produce enough of a particular hormone or may fail to release a hormone at the right time

However, the eggs hatch inside the mother and remain in the placenta where they receive oxygen and nutrients from the mother's biological system via an umbilical cord. Usually, the female has ovaries and the male testes, however a few species of fish are hermaphrodite, containing both sets of sexual organs in one individual

(The transit of the ovum from the ovary to the uterus may occur in a few hours or may take several days.) Fertilization of the ovum (the meeting of the sperm and the ovum) normally occurs about midway in the oviduct. The inner layer of the oviducts contains mucus-secreting cells that assist in transporting the ovum, and may also provide nutrients for the ovum as it travels in the oviducts

Sperm transport in the female reproductive tract


  http://humupd.oxfordjournals.org/content/12/1/23.full
As is the case in the vagina and cervix, coitus induces a leukocytic infiltration of the uterine cavity, which reaches a peak several hours after mating in mice (Austin, 1957). When vasectomized male rats were mated with females, the incidence of strong uterine contractions declined, indicating that sperm or testicular or epididymal secretions have stimulatory activity (Crane and Martin, 1991)

However, while the purpose of oocyte release and transport is for reproduction, most of the time fertilization does not occur, and in these cases the oocyte will simply degenerate as it reaches the end of the uterine tube. In addition to the cortex, the ovary also has an area called the medulla, which is located in the center of the cortex, and that's where the arteries and veins of the ovary are found
