Treatment time and frequency of the first generation IVF technology
The first generation of IVF technology refers to the in vitro fertilization (IVF) technology for infants that has been applied since the 1970s. After years of development and improvement, this technology has become one of the effective methods for infertile couples to achieve fertility. However, the success rate is not 100%. In order to improve the success rate, it is particularly important to arrange the treatment time and frequency reasonably.
Preparation before treatment
Before the first generation of IVF technology treatment, some necessary preparations need to be made. First of all, couples need to receive comprehensive physical examination, including reproductive system examination, blood and biochemical indicators testing, to ensure that the physical condition is suitable for IVF treatment. Then, according to the examination results, the doctor will develop a personalized treatment plan and give professional consultation to the couple to answer their questions and concerns about treatment.
The whole preparation period usually takes about one month. The couple needs to actively cooperate with the doctor to complete various examinations and preparations. Adequate preparation before treatment can lay a good foundation for the smooth progress of treatment.
Egg retrieval and sperm preparation stage
In the second stage of the first generation IVF treatment, it is mainly for women to take eggs and men to provide sperm samples. Women need to receive ovarian stimulation drugs to promote the development of multiple follicles. Doctors will formulate individualized medication plans according to the specific conditions of each patient, and closely monitor the growth of follicles. Generally speaking, the use of ovarian stimulation drugs needs to last 10-12 days.
At the same time, men need to provide fresh sperm samples. The hospital usually requires abstinence 3-5 days in advance to ensure the best condition of semen quality. Sperm samples can be collected by manual ejaculation or sperm donation.
The whole egg retrieval and sperm preparation phase usually takes 2-3 weeks. The arrangement of this stage requires patients and their families to have a certain time flexibility, so as to adapt to the time of egg collection and sperm collection scheduled by the hospital.
In vitro fertilization and embryo transfer
After the egg retrieval and sperm preparation stage, the key steps of IVF - in vitro fertilization and embryo culture are entered. The doctor places the collected eggs and sperm in a culture dish. After in vitro fertilization, the eggs are fertilized to form a fertilized egg. Then the fertilized eggs will be cultured in the laboratory, which usually takes 2-5 days, until the development of the embryo reaches the stage suitable for transplantation.
Embryo transfer is the last and most important step of IVF technology. Embryo transfer is usually carried out on the 3-6th day after fertilization. The doctor will transfer the appropriate embryo into the female uterus through the endometrial disposal catheter to promote the occurrence of pregnancy. The schedule of the whole IVF and embryo transfer stage is relatively tight, usually requiring 1-2 weeks.
summary
The treatment time and frequency of the first generation IVF technology should be arranged according to the specific situation. The preparation period before treatment takes about 1 month. The preparation stage for egg retrieval and sperm usually takes 2-3 weeks, while the in vitro fertilization and embryo transfer stage takes 1-2 weeks. These arrangements will provide a strong guarantee for the successful implementation of IVF technology. However, the situation of each individual may be different. Patients need to work closely with doctors and follow the guidance of the hospital to obtain the best treatment effect.
