In Vitro Fertilization, IVF is a series of procedures that is complex and is used to offer treatment for infertility or even generic problems to help in conception. In the course of the procedure, mature eggs are collected from ovaries and fertilized by sperms in the lab. There is then implantation into the uterus of the embryo that results. One cycle of In Vitro Fertilization takes roughly two weeks. This is the most effective of the assisted reproductive health technologies.

The eggs and sperms used can be from either of two sources; from the individuals themselves or from donors. Such donors could be anonymous or not. In some cases, those concerned may use other women, in which case the embryo is implanted in the uterus of these women. The chance of getting healthy babies depends on such factors as age or the cause of the infertility. The whole procedure can be expensive, invasive and time consuming. Multiple pregnancies occur when more than embryo is implanted.

When choosing the clinic, one should remember that the success rate of the clinic is dependent on a number of factors such as the age of the patient and medical issues. The treatment population of the clinic and treatment approaches used should also be considered. It is important to have information about the costs involved at each stage of the procedure.

When individuals are to use their own eggs and sperms, a number of screenings will be required. There will be ovarian reserve testing that is done to determine quantity and quality of eggs. It will involve testing the concentration of follicle stimulating hormone and estrogen during the first days of the menstrual cycle. Coupled with an ultrasound of the ovaries, the test results will help in predicting the way ovaries will respond to fertility medication.

For males, there is semen analysis that is scheduled as part of initial evaluation of fertility. This usually happens before the treatment starts. Screening for infectious diseases in both couples is also mandatory. An example of an infectious disease is HIV. For the establishment of the depth of the uterine cavity, a mock embryo transfer is carried out. The same will be instrumental in determination of techniques to be used to place embryos in the uterus.

Retrieving of eggs is done after administering of sedatives and painkillers. The most commonly used method for the retrieval is trans-vaginal ultrasound aspiration. An ultrasound probe gets inserted into the vagina to identify follicles. This is followed by insertion of a thin needle through an ultrasound guide which gets into the vagina and into follicles, enabling retrieval.

There are two techniques used for fertilization. The first is insemination that involves mixing healthy sperms and mature eggs and incubating them overnight. The other technique is intra-cytoplasmic sperm injection, known as ICSI. In this, one healthy sperm is directly injected into every mature egg. It is used when quality of semen or their number is a problem.

A number of factors determine health of babies born through In Vitro Fertilization. Reproductive history of the individual, cause of the infertility, maternal age and status of the embryo are some of the factors. Other factors include whether or not the individual smokes and their level of caffeine intake.
