Does the Fewer Follicles in IVF Affect the Success Rate?
As an assisted reproductive technology, IVF has helped many infertile couples realize their desire to have children. However, some couples may face the problem of fewer follicles. Follicles are the follicles containing eggs in the female ovary, and their number has an important impact on the success rate of IVF. This article will discuss the influence of the small number of follicles on the success rate of IVF from many aspects.
Number of follicles and ovulation problem
A decrease in the number of follicles may lead to ovulation problems in women. Under normal circumstances, women will ovulate one egg per month, but when the number of follicles is insufficient, the feasibility of ovulation will be reduced accordingly. The ovulation problem will directly affect the success rate of IVF, because there are not enough eggs for fertilization and embryo transfer.
At this time, doctors may choose to use ovulation promoting drugs to increase the number of follicles and improve the success rate of ovulation. These drugs can stimulate the ovary to produce more follicles, and monitor the ovulation cycle, so that the fertilized egg can be removed at the best time.
Number of follicles and fertilization rate
The reduction of the number of follicles will also affect the fertilization rate. In the process of IVF, eggs and sperm need to be fertilized in vitro. When the number of follicles is limited, the chance of successful fertilization will also be reduced.
In order to increase the chance of successful fertilization, doctors may take the following measures: increase the number of eggs taken, so as to obtain more eggs; Or use egg donation to get enough eggs. These methods can improve the fertilization rate, but also increase the time and cost of treatment.
Follicle number and embryo quality
The decrease in the number of follicles is also related to the quality of embryos. A small number of follicles may lead to poor quality of oocytes obtained, thus affecting the development and quality of embryos. The quality of embryos directly affects the probability of successful implantation after embryo transfer.
In this case, doctors may suggest embryo screening and only select high-quality embryos for transplantation to improve the success rate. In addition, new IVF technologies such as PGD/PGS (embryonic gene diagnosis/embryonic gene screening) can also help to screen embryos with high genetic quality.
Summary
The small number of follicles has a significant impact on the success rate of IVF. It may lead to ovulation problems, lower fertilization rate and affect embryo quality. However, with the continuous progress of medical technology, doctors have developed a series of methods to deal with these problems, such as the use of ovulation promoting drugs, increasing the number of egg retrieval and embryo screening, to improve the success rate of IVF.
Although the small number of follicles may have an impact on the success rate of IVF, it should not be too worried because modern medical technology has been able to provide a variety of solutions for infertile couples. Couples should fully communicate with doctors to develop a suitable birth plan.
