Related technologies for promoting ovulation of test tube infants
In vitro fertilization (IVF) is a process in which eggs and sperm are combined and developed into embryos, and then the embryos are transferred back to the mother to realize pregnancy and delivery. The success rate of IVF is closely related to female ovarian ovulation function, so promoting ovarian ovulation is very important for successful pregnancy. The following will introduce in detail the related technologies of IVF ovulation promotion from four aspects: drug ovulation promotion, artificial cycle regulation, follicle monitoring and surgical egg release.
Drug excretion promotion
Drug ovulation promotion is a commonly used IVF ovulation promotion technology, which mainly improves the ovarian ovulation function by taking ovulation promotion drugs. Ovulation promoting drugs are mainly divided into two categories: luteinizing hormone agonists and follicle stimulating hormone agonists. Luteinizing hormone agonists maintain the thickness and quality of endometrium, promote embryo implantation and pregnancy maintenance by simulating the secretion of luteinizing hormone. FSH agonists directly act on the ovary, promoting the development and ovulation of multiple follicles.
In the process of promoting drug excretion, doctors will choose appropriate drugs and doses according to the specific conditions of patients. This requires a detailed individualized assessment, including the patient's age, ovarian reserve function, ovulation history, etc. The success of drug delivery depends on the experience and technology of doctors, so it is very important to choose a regular and experienced hospital.
Manual cycle control
Artificial cycle regulation is another common technique for IVF ovulation promotion. By adjusting the menstrual cycle of women to make it consistent with the cycle of IVF, the promotion of ovarian function and the control of follicular development can be achieved. The commonly used methods are: avoiding follicular development stage, inhibiting follicular development stage and high luteinizing hormone stage.
Avoiding the follicular development period means making adjustments in diet, exercise, work and rest to avoid stimulating the ovary and keep it calm. This can reduce the early consumption of follicles and lay the foundation for smooth development. Inhibition of follicular development is to inhibit the premature development of follicles through the use of ovulation promoting drugs, thereby improving the pregnancy rate of patients with polycystic follicle syndrome and multiple follicular dysplasia caused by other factors. In the phase of high luteinizing hormone, after the rupture of egg cell membrane and the beginning of luteinization, high dose of luteinizing hormone is used to promote luteal development and hormone secretion.
Follicle monitoring
Follicle monitoring is a very important link in the process of IVF ovulation promotion. By monitoring the size, number and growth rate of follicles and other indicators, timely adjust the use and dosage of drugs to improve the success rate of pregnancy.
Follicle monitoring is generally carried out by ultrasonic examination and blood test. Ultrasound can observe the size and number of follicles and understand their growth. The blood test can detect the levels of hormone such as follicle stimulating hormone and estrogen, and help judge the development degree of the follicle and the time of ovulation.
Surgical release of eggs
When the follicle develops to a certain extent, the doctor may choose to release the egg by surgery. This method is mainly applicable to patients with ovulation dysfunction. The surgical release of eggs is usually carried out by laparoscopy or fine needle puncture, and the specific choice depends on the specific situation of the patient and the doctor's recommendation.
The surgical release of eggs has certain risks, such as infection, bleeding, etc., so it needs to be carried out under the guidance of regular hospitals and experienced doctors. After the operation, the doctor will also monitor and regulate the pregnancy according to the patient's situation to ensure the smooth progress of pregnancy.
summary
The related technologies of IVF ovulation promotion include drug ovulation promotion, artificial cycle regulation, follicle monitoring and surgical egg release. The application of these techniques should comprehensively consider the individual differences and circumstances of patients, and select appropriate methods and doses. Regular hospitals and experienced doctors are the key to the success of IVF pregnancy. Patients should closely cooperate with the monitoring and guidance of doctors during the treatment process to improve the probability of successful pregnancy.
