Hum Reprod ;7 5 The technique was further advanced at the Center for Reproductive Health at the University of California , Irvine, when Asch and his associate Jose Balmaceda employed a newly developed catheter into the GIFT procedure that eliminated the need for general anesthesia in the later stages of the procedure. On average, the GIFT cycle takes four to six weeks before fertilization occurs.

The hormonal treatments are administered in order to promote the development of oocytes, which are the precursor to eggs stored in the ovaries. For the highest chance of success with GIFT, fully mature eggs are essential. Once the sperm is capacitated, , to , motile sperm are utilized in the GIFT procedure. For the highest chance of success with GIFT, an estimated 1.

The catheter contents are separated by air to prevent fertilization prior to the transfer. The transfer of multiple oocyctes carries the possibility of multiple pregnancies, which occurs in an estimated thirty percent of assisted reproductive pregnancies.

Because the GIFT procedure closely resembles natural or unassisted reproduction, it is one of the few reproductive technologies approved by the Vatican: no decisions are made as to which embryos are implanted or discarded, the embryo itself is not manipulated, and fertilization occurs naturally in vivo rather than artificially in vitro.

However, one point of contention with Catholic doctrine results from obtaining sperm through masturbation. GIFT is a viable treatment for infertility caused by certain ovary disorders, endometriosis , and cervical problems, but it does not treat women with untreated fallopian tube blockages.

GIFT requires at least one healthy fallopian tube, whereas treatments such as in vitro fertilization do not. This usually involves a minor surgical procedure which allows you to go home the same day with a minor degree of pain that lasts for just a few days.

The egg enters the fallopian tube where it meets with sperm that have traveled there, following intercourse, from the vagina. The sperm normally fertilize the egg in the fallopian tube. The fertilized egg, now called an embryo, begins to divide and in four days, contains many cells. The embryo then implants in the uterine wall, and becomes a pregnancy. The GIFT technique follows nature by allowing the eggs to fertilize and develop in the natural environment of the fallopian tube, and then to make their way to the uterus for implantation according to a normal timetable.

In contrast, in vitro fertilization IVF places fertilized eggs directly into the uterus. The fluid containing the eggs is placed in a laboratory dish and observed under a microscope. The egg is located and its stage of maturity noted. It is then carefully cultured in a special nutrient.
