For women who are unable to get their eggs fertilized through normal conjugal processes, they can opt for clinical intervention to increase their chances of pregnancy. In the lab, the egg cells are put through artificial insemination in order to fertilize the eggs, which are then transferred to the uterus of the woman. The rate of success has increased with the rapid advances of such procedures and hence, for couples who have faced failure in normal conception, it is worth their while to invest in such procedures.
What is IVF?
IVF or in vitro fertilization is a procedure of artificial insemination of eggs and to help increase chances of successful conception. From the first steps of success of in vitro fertilization in Singapore by which the first child was produced in England in the year 1978, today the treatment has undergone several advances and changes to make the procedures more hopeful for couples who opt for such treatment. There are several steps involved in IVF where a cycle takes three weeks to complete. The procedures include outpatient methods that are administered to the woman. She is given hormonal injections that help stimulate the ovarian follicles. There are ten days of hormonal procedures followed along with which medications are also given in order to increase the chances of the egg being implanted in the uterus.
Retrieval of eggs
Besides hormonal injections and treatment of the woman who wishes to conceive, the cycle of ovulation is followed and egg cells are retrieved by a transvaginal procedure. Before the treatment is started certain tests are done to ascertain the reproductive health of the man and women who wish to undergo the treatment. This includes sperm motility analysis for men as well. In case there is any requirement for treatment on the man’s part, this is first taken up. In case the problems are difficult to solve, couples are given the option of donor sperms or eggs that can be used.
Lab fertilization methods
When the eggs and sperm of a couple undergoing IVF are found to be healthy, the eggs and semen are incubated for eighteen hours. An egg is injected with a sperm and left in a growth medium for a period of 24 hours or more till a six or eight cell stage is reached. The embryos formed, about three to four, are transferred back to the uterus. To increase chances of embryo implantation the uterus lining is thickened and progesterone hormones are given to help in this process. Success rates in each cycle are about twenty to thirty percent. Many couples nowadays find success with IVF procedures to bring a new life into their world.
