What is the role of 14 day hCG in IVF?
Test tube baby technology is a modern medical technology, which aims to help couples who cannot conceive naturally realize their reproductive dreams. HCG (human chorionic gonadotropin) is a hormone that plays an important role in IVF treatment. This article will elaborate on the role of 14 day hCG in IVF from the following four aspects.
1. Promote ovarian ovulation and egg development
In the process of IVF treatment, the primary task is to promote ovarian ovulation and egg development. Under normal circumstances, women will only discharge one mature egg per month. However, for IVF treatment, as many healthy eggs as possible are needed to improve the pregnancy success rate. One of the functions of hCG is to stimulate ovarian development and promote the simultaneous development and maturation of multiple eggs. Hospitals usually determine the appropriate hCG dose according to the patient's physique and condition.
Secondly, hCG can also help to determine the best pregnancy time. In a period of time after the egg develops and matures, the doctor will implant the fertilized egg into the uterus through blastocyst transfer at an appropriate time to improve the success rate of implantation and pregnancy. This process requires strict control of time and dose, and the application of hCG plays a key role here.
2. Promote luteal formation and maintenance
The corpus luteum is a temporary gland formed by the ovary after ovulation. The progesterone secreted by corpus luteum plays an important role in early pregnancy. Progesterone can maintain the stability and growth of endometrium and provide support for the implantation of fertilized eggs. However, in IVF technology, the function of luteal formation and maintenance is often insufficient because there is no hormone regulation in natural cycle. The application of hCG can supplement the secretion of ovarian progesterone, ensure the stability and development of endometrium, and provide a favorable environment for fertilized eggs.
It is worth mentioning that although hCG can bring about progesterone secretion, it may also cause some side effects, such as breast pain, abdominal distension, mood fluctuations, etc. Doctors in the hospital will carefully monitor and adjust according to the patients' conditions to ensure the safety and effectiveness of treatment.
3. Test pregnancy results
IVF treatment is a long and intense process, and patients will usually be tested for hCG after blastocyst transfer. HCG is produced relatively early in the body and can be detected by blood or urine to determine whether pregnancy is successful. This test is usually performed about 14 days after blastocyst transfer, which is why the hCG test is called "14 day hCG test for test tube infants".
By detecting the level of hCG, doctors can determine whether the pregnancy is successful and conduct further treatment evaluation. If hCG is positive, it means successful pregnancy. At this time, the doctor will evaluate the progress of pregnancy according to the change of hCG level. If the level of hCG gradually rises, it may indicate the development of normal pregnancy; If the level of hCG drops, it may mean the risk of miscarriage. If the hCG test is negative, the IVF treatment fails, and the treatment plan needs to be re evaluated and adjusted.
4. Promote placental formation and pregnancy stability
After successful pregnancy, the role of hCG did not end. HCG can also promote the formation of placenta and maintain pregnancy stability. The placenta is an important organ in the process of embryonic development. It can provide oxygen and nutrients for the embryo, and secrete hormones to maintain pregnancy. HCG can stimulate the development of placenta, increase the function and stability of placenta, and provide guarantee for the smooth progress of pregnancy.
In conclusion, 14 day hCG of IVF plays an important role in IVF treatment. It promotes ovarian ovulation and egg development, and helps to determine the time of conception; Promote the formation and maintenance of corpus luteum and maintain the stability of endometrium; To detect pregnancy results and evaluate pregnancy progress; Promote placental formation and pregnancy stability. The success rate of IVF treatment and the stability of pregnancy can be increased by precisely controlling the dosage and timing of hCG.
