Is there a high probability that three generations of test tube babies will conceive boys?
The third generation of IVF refers to the method to help couples solve fertility problems in different generations through in vitro fertilization and embryo transfer technology. It is well known that the sex of boys and girls is determined by the chromosomes carried by the father's sperm. So, will the probability of carrying out three generations of IVF to conceive boys be higher? This article will discuss this problem from the perspective of reproductive medicine.
1. Freshness of male sperm and embryo selection
The freshness and activity of male sperm play an important role in the process of pregnancy. Research shows that in the periodic monitoring, the female ovary has the highest probability of fertilization within 24-36 hours after ovulation. Therefore, if the fertilization process can be completed within 24-36 hours through the three generation IVF technology, the freshness of male sperm will have a positive impact on the breeding of boys.
In addition, embryo selection can also increase the probability of boys. Some studies have shown that in the process of embryo culture, the sex of the embryo can be determined by detecting the embryo, and the embryo that is more biased towards boys can be selectively transferred. Although this technology has been launched in some hospitals, it is controversial in legal and ethical aspects, and is still prohibited in some countries.
In general, the freshness of male sperm and embryo selection have a certain impact on the probability of three generations of IVF to conceive a boy, but it cannot be simply said that IVF can improve the probability of conceiving a boy.
2. Uterine environment and fertility of boys
The uterine environment is also an important factor affecting the sex of IVF. The study found that the intrauterine environment has a significant impact on the viability and fertility of sperm. The acidic environment is more conducive to the survival and fertilization of male sperm.
In the process of three generations of IVF, it is helpful to improve the fertilization ability of boys by adjusting the uterine environment, such as the thickness and pH of endometrium. However, whether in natural pregnancy or IVF, there is still controversy about the gender selection of the uterine environment, which has relatively little impact and cannot be regarded as a decisive factor to improve the probability of conceiving a boy.
3. Parental genetic factors and the probability of boys
The sex of boys and girls is determined by the sperm of the father. Some studies have found that the genetic factors of the father can affect the sex selection of fertilization. Specifically, the number and activity of the Y chromosome in the father's sperm are related to the probability of the boy.
In the process of three generations of IVF, the chromosome analysis and screening of the father can help to determine the quantity and quality of Y chromosome in male sperm, and select sperm with more Y chromosomes for fertilization. This technology can improve the possibility of conceiving a boy, but it is not 100% guaranteed.
4. Environmental factors and probability analysis
In addition to biological factors, environmental factors may also affect the probability of conceiving boys. Some studies have found that in some special environments, such as high altitude areas and high-temperature environments, the probability of conceiving a boy is relatively high.
However, in the process of three generations of IVF, there is no clear evidence that environmental factors can directly improve the probability of conceiving boys. These impacts may exist, but they are not decisive factors.
Summary
To sum up, there are some factors that can help improve the probability of conceiving a boy among the three generations of IVF, such as the freshness of male sperm and embryo selection, the regulation of uterine environment, and the genetic factors of the father. However, these factors are not absolute and cannot guarantee 100% gender selection. Sex selection in IVF is, to a large extent, a technological means rather than a deterministic science. Therefore, when deciding whether to choose IVF, both husband and wife should fully understand the relevant medical knowledge and laws and regulations, carefully consider their own family and living conditions, and make a wise decision.
