What are the steps before IVF transplantation

IVF is an assisted reproductive technology, which is suitable for couples who cannot conceive naturally due to reproductive system reasons. Before IVF transplantation, a series of steps and checks are required to ensure the smooth progress of the whole process. This article will elaborate on the steps before IVF transplantation from many aspects.

Medical examination and evaluation

Before IVF transplantation, both couples need to undergo a series of medical examinations and evaluations. This includes semen analysis of the man, endocrine examination and uterus examination of the woman. Doctors need to assess whether couples have the appropriate conditions for IVF transplantation, such as the female's ovarian function, the thickness and quality of endometrium and other factors. The first step is to conduct endocrine examination to determine the condition of the woman's ovarian function. This can be assessed by blood tests to assess female hormone levels. If the hormone level is normal, the next step is to check the ovary through ultrasound to determine whether there are enough follicles for collection. In addition, the semen of the man will be examined to assess the quality and quantity of sperm.

Auxiliary ovulation induction therapy

If the ovarian function of the woman is not ideal, the doctor may recommend auxiliary ovulation induction treatment. This usually includes the use of ovulation promoting drugs to stimulate ovarian development. The specific treatment plan will be determined according to the specific conditions of each patient. The doctor will closely monitor the development of follicles to determine the best time for collection. Once the follicle reaches the stage of sufficient maturity, the doctor will arrange the collection of eggs. This is usually done by transvaginal ultrasound guided ovarian puncture. This process requires local anesthesia and is performed in the operating room. The eggs collected will be sent to the laboratory for preparation and processing.

In vitro fertilization and embryo culture

In the laboratory, the eggs collected will be fertilized with semen in vitro. This process is usually performed by in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). The doctor will choose the most suitable fertilization method according to the specific situation of the patient. After fertilization, the embryo will be cultured in the laboratory. Doctors will select the best embryo for transplantation according to the development and quality of the embryo. Normally, the incubation time will last for 2-6 days.

IVF transplantation

IVF transplantation is the last step in the whole process. The doctor will select the best embryo and use a thin tube to implant it into the woman's uterus. This process is usually painless and does not require surgery. Two methods of transfer can be adopted, one is fresh embryo transfer, that is, the selected embryos in the culture phase are transferred immediately; The other is frozen embryo transfer, that is, the surplus embryos are frozen for future use. To sum up, the steps before IVF include medical examination and evaluation, assisted ovulation therapy, in vitro fertilization and embryo culture, and IVF. These steps ensure the smooth progress of the whole process and provide the best opportunity to realize the couple's fertility aspirations. Through scientific and technological means, IVF transplantation provides a new reproductive option for couples who cannot conceive naturally.
