How long does the IVF cycle take?
IVF is a kind of assisted reproductive technology, which aims to help couples who are difficult to conceive naturally realize their reproductive aspirations. The length of IVF cycle varies with individual differences and various factors. In this article, we will elaborate on the time required for IVF cycle from the following aspects.
1. Screening and preparation stage
The first phase of the IVF cycle usually involves preliminary evaluation and screening of couples to determine the suitability of IVF technology.
At this stage, couples will undergo a comprehensive physical examination and reproductive system assessment to determine whether there are any potential fertility problems. These tests may include blood and urine tests, ultrasound tests, semen analysis, etc. Doctors also assess the couple's lifestyle, genes and family history.
The entire screening and preparation phase usually takes several weeks, depending on the hospital process and the couple's personal situation. Some hospitals may need additional time to complete more detailed examinations and professional assessments.
2. Ovulation induction and egg collection
The second stage of the IVF cycle involves ovulation induction and egg collection. At this stage, women will receive medication to promote the growth and maturation of multiple eggs.
Usually, women need to inject specific fertility hormone drugs every day to stimulate the ovaries to produce more eggs. Doctors will conduct regular ultrasound and blood tests to monitor the growth of eggs and hormone levels.
Once the eggs reach the optimal mature state, doctors will use ultrasound guided puncture technology to collect eggs from the ovary. This process usually requires local anesthesia and is completed within one day.
3. Fertilization and embryo culture
After egg collection, the egg will be fertilized with sperm in vitro. This process is usually carried out in the laboratory.
The doctor will select the best sperm and combine it with the egg to promote fertilization and embryo formation. Once fertilization occurs, the embryo will continue to be cultured in the laboratory for several days to ensure its further development.
The length of embryo culture depends on the decision of doctors and couples. Some couples may choose to transfer embryos when they reach a specific stage, while others may choose to freeze embryos for future use.
4. Embryo transfer and progesterone treatment
At the end of the embryo culture phase, the embryo will be transferred back to the female uterus. This process is usually carried out in a doctor's clinic or hospital.
The process of embryo transfer is relatively simple and usually does not require anesthesia. Doctors use thin tubes to place the embryo directly in the uterus to help the embryo implant and continue to develop.
After embryo transfer, women may need to receive progesterone treatment to promote endometrial health and embryo implantation. This means that women need to inject or take drugs every day for several weeks until a pregnancy test.
In general, the IVF cycle usually takes several months to complete, depending on the couple's personal conditions and hospital procedures. In addition, the IVF cycle also involves important psychological and emotional processes, and couples need to be patient and mentally prepared throughout the process.
