Preimplantation Genetic Diagnosis (PGD) is a medical process by which an embryo's genetic information is analyzed before implantation in the uterus. It can also be used to determine the sex of the baby. If you're interested in pursuing this process, start by contacting a clinic near you that performs this type of procedure. PGD coupled with In-Vitro Fertilization (IVF) is one of the only ways to choose a baby's sex with absolute certainty. However, it's also one of the most expensive, resource-intensive methods available. If the clinic agrees to perform this procedure, the female partner will probably need to begin preparing to donate eggs several weeks to a month in advance. Generally, women undergoing PGD and IVF are given fertility drugs to stimulate the ovaries to release more mature eggs.  Usually, fertility drugs are taken for about two weeks via pill or injection.  Side effects for common fertility drugs are usually mild and can include include hot flashes, nausea, bloating, headache, and blurred vision. In addition to taking fertility drugs, women who intend to donate eggs usually also receive a series of daily hormone injections. These injections further stimulate the ovaries to release more mature eggs.  Some women have strong side effects to these hormones, so first-timers are generally monitored carefully to ensure that the process is proceeding smoothly. You may also be required to take progesterone, a hormone that thickens the uterine lining in preparation for IVF. As the female partner's body is stimulated to release more eggs, regular ultrasound tests are used to determine when the eggs are ready to be donated. When the eggs are fully mature, there is a simple, minimally-invasive surgical procedure to remove the eggs. Most women are able to resume normal activities within a day or so of this procedure. Though the female partner is put under sedation for this procedure, it can be somewhat uncomfortable. Painkillers are usually prescribed to aid with post-surgery pain. If the male partner does not already have a stored sperm sample ready to use, he must now provide it. The male partner’s sperm is processed to isolate the healthiest, highest-quality sperm, and combined with the eggs. Within about a day, the eggs are checked to see whether or not they have been fertilized. As with all sperm donations, in this case, the male partner will want to abstain from ejaculating for about 48 hours before giving his sperm donation. After the embryos have grown for several days, a doctor removes several cells from each for testing and analysis. DNA is removed from each cell sample and copied via a process called the Polymerase Chain Reaction (PCR). This DNA is then analyzed to determine the embryo's genetic profile, including the sex of the child that could potentially grow from the embryo. After the cells from each embryo have been analyzed, you are notified which embryos are male and which are female, in addition to any other pressing information (such as the presence of genetic diseases). When you've chosen which embryo(s) you'd like to attempt pregnancy with, the embryos are transferred into the uterus via a thin tube passing through the cervix. Usually, only one or two embryos are transferred at a time. During a successful attempt, one or more embryos attach to the uterine wall and pregnancy continues as normal.  In two weeks, you may take a pregnancy test to see whether or not the procedure was a success. Don't be deterred by one unsuccessful IVF attempt. Generally, most women have a per-cycle success rate of about 20-25%. Success rates of 40% or higher are considered quite rare. It's often necessary for perfectly healthy couples to have to undergo multiple rounds of PGD and IVF to achieve their desired pregnancy.
