Selection of down-regulation drugs for IVF
Test tube baby technology is an assisted reproductive technology, which has become more and more common in many infertile couples. The technology includes several steps, one of which is the descending of IVF. Descending IVF refers to the use of appropriate drugs to adjust the function of the female reproductive system, create a suitable environment before embryo transfer, and improve the success rate of pregnancy. In the process of IVF lowering, a variety of drugs can be used to help adjust the function of the female reproductive system. This article will introduce the choice of IVF drugs from four aspects.
1. Anti androgen drugs
Anti androgen drugs are one of the commonly used drugs in IVF downregulation. Such drugs usually include progesterone and GnRH agonist/antagonist. Progesterone is an estrogen analogue, which can enhance the formation and maintenance of endometrium during IVF and improve the chances of embryo implantation. Lepidosterone is an antiandrogenic drug, which can effectively inhibit luteinization, and inhibit the synthesis and secretion of gonadal hormones, thus regulating the function of the female reproductive system.
When using antiandrogen drugs, it is necessary to ensure the appropriate dosage and timing. Doctors will choose and adjust drugs according to the specific conditions of patients. Improper use of drugs may lead to side effects, such as headache, nausea, breast pain, etc.
2. Growth hormone drugs
Growth hormone drugs are also one of the commonly used drugs in IVF down-regulation process. Growth hormone plays an important regulatory role in the ovary and endometrium, and can promote follicular development and embryo implantation. Therefore, the use of growth hormone drugs can increase the chance of successful pregnancy.
Some growth hormone drugs include human chorionic gonadotropin (hCG) and follicle stimulating hormone (FSH). These drugs often need doctors to adjust the dosage and use timing according to the specific conditions of patients.
3. Supplement drugs
In the process of IVF lowering, it is sometimes necessary to supplement some drugs to adjust the patient's physical condition and improve the comprehensive immune function in the body. For example, vitamin and mineral supplements can increase the reserves of nutrients in the body and provide the nutritional conditions needed for embryonic growth. In addition, some antioxidants can also be added, because antioxidants can reduce the production of free radicals and protect eggs and embryos from damage.
4. Anticoagulants
In the process of IVF lowering, anticoagulants are sometimes used to reduce the risk of blood coagulation. These drugs usually include heparin and low molecular weight heparin. Anticoagulant drugs can prevent coagulation reaction in the blood, reduce the risk of thrombosis, and thus improve the blood flow of patients.
Although anticoagulants are used in the process of IVF down-regulation, it is still necessary to determine the appropriate dose and use time according to the specific situation of the patient and the guidance of the doctor.
summary
The choice of drugs in the process of IVF downregulation is very critical, and different drugs have different effects. Appropriate antiandrogens can adjust the function of female reproductive system, growth hormone drugs can help follicular development and embryo implantation, supplements can improve the body's immune function, and anticoagulants can reduce the risk of blood coagulation. When using drugs, they need to be adjusted according to the specific situation of the patient and the doctor's suggestions to ensure safety and effectiveness.
