Why IVF needs these steps

IVF technology is an assisted reproductive technology, which helps couples who cannot conceive naturally realize their reproductive dreams through in vitro fertilization and embryo transfer. This process needs to go through multiple steps, and each step has its specific purpose and role. This article will elaborate on the reasons why IVF needs these steps from four aspects.

Patient assessment and infertility survey

The first step of IVF technology is to conduct patient evaluation and infertility survey for couples. The purpose of this step is to understand the physical condition of the couple and the causes of infertility, so as to determine the appropriate treatment plan. During the evaluation process, doctors will conduct detailed physical examination, medical history inquiry and laboratory tests to obtain necessary information. Only through adequate evaluation and investigation can doctors identify the causes of infertility and formulate the most appropriate treatment plan. In the process of patient evaluation and infertility investigation, male semen analysis is also required to assess male fertility. This is because male infertility is an important factor in the decline of IVF technology success rate. Through this step, doctors can determine whether sperm quality improvement or assisted reproductive technology is needed.

Ovulation induction and egg collection

One of the key steps of IVF is ovulation induction and egg collection. Under normal circumstances, women only ovulate one egg per month. If you want to obtain more eggs to increase the success rate, you need to stimulate the ovary to produce multiple follicles through ovulation promoting drugs. The development of multiple follicles means that more eggs can be collected, which increases the chance of IVF success. Egg collection is a minor operation. The mature eggs are extracted by puncturing the ovary with a fine needle guided by transvaginal ultrasound. For women, this is a minor trauma, but it is a necessary process to obtain eggs.

Sperm processing and in vitro fertilization

Sperm processing and in vitro fertilization are the key links of IVF technology. In this step, there are two options: conventional in vitro fertilization and microporous fertilization. Conventional in vitro fertilization is to place sperm and egg directly in the same culture dish, and let sperm naturally enter the egg for fertilization by creating an environment similar to in vivo fertilization in vitro. Micropore fertilization is a more delicate operation, in which sperm is injected by making tiny holes around the egg. This method is applicable to some special situations, such as the situation where the number of sperm is small or the sperm activity is poor, which can improve the chance of successful fertilization.

Embryo transfer and pregnancy monitoring

Embryo transfer and pregnancy monitoring are the final stages of IVF technology. Cultured and developed embryos will be transferred back to the female uterus at a specific time. Embryo transfer is a simple operation that usually does not require anesthesia. After transplantation, women need to continue to carry out pregnancy monitoring to confirm whether the pregnancy is successful. Pregnancy monitoring uses blood tests and ultrasound to determine whether the embryo has successfully implanted and developed. If the pregnancy is successful, the doctor will continue to monitor the health of the embryo until the successful end of pregnancy. In summary, IVF needs to go through a series of steps such as patient evaluation and infertility investigation, ovulation induction and egg collection, sperm processing and in vitro fertilization, embryo transfer and pregnancy monitoring. The purpose of these steps is to fully assess the physical condition of the couple and the causes of infertility, provide more opportunities to obtain eggs, increase the success rate of embryo fertilization, and monitor the progress of the pregnancy process in real time. Through the comprehensive cooperation of these steps, IVF technology can help couples who cannot conceive naturally realize their reproductive dreams.
