What conditions does IVF need to succeed?
In vitro fertilization (IVF) and embryo transfer (ET) in assisted reproductive technology (ART) have become an effective way for many infertile couples to realize their reproductive dreams. However, to make IVF successful, a series of specific conditions and requirements are required. This article will discuss the conditions for successful IVF from the aspects of monitoring ovulation cycle, artificial insemination, embryo quality assessment and pregnancy environment.
Monitor ovulation cycle
Monitoring the ovulation cycle is the first step for IVF success. Generally, only one egg per month can be fertilized by a woman. Therefore, it is very important to accurately determine the ovulation time of women. Common ovulation monitoring methods include basic temperature recording, transvaginal ultrasound monitoring and urine ovulation test paper measurement.
The basic body temperature record refers to the use of a thermometer to measure the oral temperature and record the data every morning after a woman wakes up. When the body temperature continues to rise, it indicates that ovulation is about to occur. Vaginal ultrasound monitoring can judge the ovulation time by monitoring the growth of follicles and the formation of corpus luteum. Urine ovulation test paper can accurately predict the ovulation time by detecting the change of luteinizing hormone (LH) level in urine.
Only when the monitoring cycle is accurate can we arrange a suitable time for the next operation of IVF.
artificial insemination
Artificial insemination is an important step in IVF technology. It uses sperm and egg to fertilize in vitro, and the fertilized egg is formed through laboratory operation. For couples with good sperm quality, gender specific sex selection techniques can be selected to increase the chance of pregnancy.
However, artificial insemination also needs to meet certain conditions. First of all, men need sufficient quantity and quality of sperm to fully fertilize eggs. Secondly, women need to have healthy ovarian function and unobstructed fallopian tubes so that the fertilized eggs can enter the uterus.
If the quality of male sperm is poor or the function of female ovary is damaged, sperm or egg donation may be needed to improve the chances of success of IVF.
Embryo quality assessment
Embryo quality assessment is the key to the success of IVF. The quality of embryo directly affects the success rate of pregnancy. Generally, the appearance, cell number, development speed and genetic evaluation of embryos are the main indicators to measure the quality of embryos.
Appearance evaluation is based on the shape, size and comprehensive performance of embryos, including endometrial blastocysts, polycystic embryos and mature embryos. The evaluation of cell number is to judge the growth potential and differentiation of the embryo by observing the number and structure of cells in the embryo. The evaluation of development speed is to evaluate the quality of embryos by observing the timeliness of embryo development and the completion of steps. Genetic evaluation is to determine the chromosomal structure and gene mutation of the embryo through embryo biopsy or cell sampling in the early stage of IVF.
After embryo quality assessment, doctors can choose the best embryo to implant, so as to improve the success rate of IVF.
Breeding environment
The pregnant environment is also one of the important conditions for the success of IVF. The proper pregnant environment plays a vital role in the growth of embryos and the maintenance of pregnancy. The pregnant environment includes the intrauterine environment, diet adjustment and mental health.
Endometrial environment refers to factors including endometrial thickness, uterine wall compliance and congestion. A good intrauterine environment is conducive to the implantation of fertilized eggs and the healthy development of embryos. Dietary adjustment refers to properly increasing the intake of foods rich in protein, vitamins, minerals and antioxidants to provide nutrients and energy for embryos. Mental health refers to the good mentality and positive attitude of mothers and family members, which is conducive to reducing stress and anxiety and promoting the success of IVF.
Summary
The success of IVF needs to meet a series of specific conditions. Monitoring the ovulation cycle ensures that artificial insemination is carried out at the right time. Artificial insemination needs to meet the quality of the couple's sperm and eggs. The embryo quality assessment can select the most suitable embryo implantation, and the appropriate breeding environment is conducive to the growth of the embryo and the maintenance of pregnancy. Only when these conditions are met can the success rate of IVF be maximized.
