What is In Vitro Fertilization
In vitro means a procedure formed outside an organism. In vitro fertilization of IVF is impregnation or insemination that occurs outside a woman's fallopian tubes. It is a noninvasive procedure. A colloquial term for babies delivered from this procedure is "test tube babies."
This procedure, although very popular, is only intimately known by people who have actually had in vitro fertilization. In this article, we'll some basic information on IVF, from the procedure to the costs.
The cost of invitro fertilization usually ranges from $9,000 to $14,000. People who opt for IVF usually have fertility problem such as endometriosis which is an ovulation disorder or a blocked fallopian tube. The problem may also lies with men who have low sperm count or sperm immotility.
IVF requires healthy sperm, a healthy ovum, and a uterus for the embryo. Some drugs, such as clomiphene citrate may be given to a woman so that she is able to get more ova which will help in ovulating., Monitoring of estradiol levels which is a type of estrogen and follicular growth is also done.
When the follicles are considered mature, hCG, which causes ovulation is injected within 42 hours. The eggs are then retrieved using a transvaginal technique with the aid of an ultrasound. The egg and semen are then incubated in a culture media for about 18 hours. Usually, that will be enough for the egg to get fertilized.
It is then left in a special medium for 48 hours and by then it would have doubled into 6 or 8 cells. The embryos are judged by the embryologist based on the number of cells, evenness of growth, and degree of fragmentation. The embryos judged to be the best are then transferred to the body of the uterus in the woman.
The woman is then usually advised to limit her physical activity on the day of the transfer of the embryos. A pregnancy test is administered 9 to 11 days after the transfer. Any leftover embryos after a successful pregnancy maybe donated to another couple.
Since IVF has been around for a while, studies have shown no long term complications on children. Women who go through in vitro fertilization have a higher chance of having multiple gestations, which is having twins, triplets, etc. Because of this, many women choose to have only one embryo transferred to minimize the chance of multiple gestations.
Furthermore, women who make use of IVF have a higher chance of ectopic pregnancy, a case in which the fetus lies outside the uterus. In 2008, the National Birth Defects Study in the United States found that certain birth defects are more common in infants conceived with IVF, including septal heart defects esophageal atresia, and cleft lip with or without cleft palate.
On average, delivery is achieved in 28% using fresh non donor embryos and 54% using fresh donor embryos. Success rates vary by maternal age and number and quality of egg, sperm, and embryos. The most favorable rates are seen in women under 35.
The advantages of IVF certainly seem to outweigh the disadvantages for many women. It has proven to be quite a popular procedure for women with infertility problem and for single women and lesbians. The success stories which have spanned multiple decades and many countries and cultures are a testament to the appeal of this amazing procedure.
