etting Pregnant and Improving Fertility: Heparin
Among several types of fertility drugs aimed at improving fertility for couples trying to get pregnant is Heparin, a medication that is often used to treat complications affecting the blood, and is sometimes used as part of an infertility treatment. But just what types of fertility problems can Heparin help to address? And what are some of the symptoms associated with this fertility drug?
What is Heparin?
Heparin is considered a blood thinner medication, also known as an anticoagulant. However, this fertility drug does not actually thin the blood, but instead helps prevent blood clotting or the growth of previously formed blood clots. As such, Heparin does not dissolve already existing blood clots, and is often given in small doses alongside low level-aspirin therapy as part of an overall fertility treatment.
Heparin works by inactivating the thrombin compound, which is found in blood and which is essential to the clotting process. Thrombin inactivation causes platelets in the blood to become less sticky, making them less likely to bind together and form blood clots.
Heparin and Fertility
For the most part, Heparin helps treat female fertility problems – particularly those that affect sustaining a full pregnancy as a result of multiple miscarriages or stillbirth. This is because Heparin helps prevent blood clotting, which can affect the placenta in pregnant women with high levels of antiphospholipid antibodies.
Blood clots in the placenta can interfere with the passage of oxygen and nutrients to the fetus, putting the baby at risk. In addition, blood clots can affect the makeup of the placenta, making it difficult for an egg to become implanted.
There are still some debates regarding the effectiveness of Heparin in terms of improving fertility; however, studies have shown that a combination of low dose aspirin with Heparin can increase the odds of carrying a pregnancy to term, resulting in a 60 to 75% chance of live birth.
Heparin is available in oral forms, but may also be administered by subcutaneous injections that typically begin with small doses and may be accompanied by low doses of other fertility drugs.
Heparin Side Effects and Risks
More studies need to be conducted in order to adequately address the potential risks of taking Heparin during pregnancy – particularly, during the third trimester. Nonetheless there are some known side effects and risks associated with this fertility treatment. Some of the common side effects of Heparin include:
