IVF and Recombinant Medicines

Uncategorized

If you’ve exhausted low-tech therapies and you’re still not pregnant, it may be time to turn to assisted reproductive technologies, or other high-tech therapies and new medicines.
In Vitro Fertilization: First Choice For Many

When a couple has trouble conceiving with low-tech therapies, doctors may recommend that some patients move directly to in vitro fertilization(IVF).  Usually, if you are over age 35 or have been diagnosed with blocked fallopian tubes this is a good place to start.

Choosing the Best Embryos

One of the advantages of IVF is that doctors can choose the embryos with the best chances of implantation and reduce the risk of multiple births.

During IVF, a man’s sperm and a woman’s eggs are combined in a laboratory dish, where fertilization occurs.  Some of the resulting embryos are transferred into the woman’s uterus to develop naturally.1 One advantage of using IVF over artificial insemination is that the doctor can select the embryos with the best chances of implantation and control the number of embryos transferred to reduce the risk of multiple births.

To prepare for IVF, the woman undergoes a series of daily injections with follicle-stimulating hormone (FSH) that is sometimes used in combination with human menopausal gonadotropin (hMG) to stimulate growth of follicles within her ovaries and maturation of eggs. In order for ovulation to occur at the right time, a hormone medication known as human chorionic gonadatropin (hCG) is usually given. HCG causes the final maturation and release of mature eggs.

Recombinant FSH and Other Newer Medicines

There are also newer medicines readily available. One such medicine is recombinant FSH. Because of this breakthrough in 21st century technology, recombinant products provide consistent drug doses from one vial to the next and an ample supply of drugs because there is no dependence on urine collection or donor availability.

Less Medicine, Real Benefits

Studies show that recombinant FSH may require less medicine and fewer injections. It may also require fewer days of treatment before eggs can be retrieved for fertilization.

Studies have shown that recombinant FSH is efficient, requiring less medicine and fewer days of treatment to reach the point that eggs can be retrieved for fertilization. This means that women need fewer injections which can be a real benefit for women undergoing numerous, daily self-injections.

In addition, some doctors believe that recombinant FSH allows them to collect more eggs per retrieval, which provides more options for choosing which eggs to fertilize and transfer to the uterus. The fertilized eggs not used during a pregnancy attempt may be frozen and saved for future attempts, if necessary.

Recombinant FSH is more than 99 percent pure and free from potential urinary proteins. Talk to your doctor about which fertility medications are right for your situation.
