Scientific Methods for Choosing Baby's Gender in IVF Procedures

Artificial insemination or what is known as "IVF" (In Vitro Fertilization) is one of the most effective solutions for treating infertility and various reproductive problems. However, it also raises many important questions about the possibility of controlling fetal characteristics, specifically gender. This question reflects a natural curiosity among many couples undergoing IVF procedures. In this comprehensive article, we will review the scientific methods used to determine baby's gender during IVF procedures, the extent to which they can be applied, and their ethics in Islamic and Arab societies. We will focus on scientific facts, religious restrictions, and ethical considerations that you should take into account.

Can Fetal Gender Be Selected in IVF Procedures?

In general, artificial insemination (IVF) or intracytoplasmic sperm injection (ICSI) is not used to directly select fetal gender. Fetal gender is determined naturally at fertilization through the sperm, as the sperm is what carries either an X chromosome or a Y chromosome. However, with the use of genetic testing of embryos (PGT), it has become possible to know fetal gender before implantation and thus select an embryo of a particular type if there is a clear medical need for it. This distinction is very important: technical possibility does not mean medical necessity or religious permissibility.

The Difference Between Knowing and Selecting Gender

It is very important to understand the difference between knowing fetal gender and selecting it. Knowing gender is medical information that may be necessary in certain specific cases. However, selecting gender based solely on personal desire is an entirely different matter and is not permitted in most Islamic and Arab countries. Genetic testing can provide information, but the final decision should be based on clear medical and religious grounds.

How Is Fetal Gender Determined Scientifically?

The scientific process of determining fetal gender requires several precise steps and highly advanced techniques. After embryo development (5-6 days after fertilization), a very small biopsy is taken from each embryo to analyze DNA and confirm its chromosomal integrity. This process requires very high expertise and specialized techniques.

Chromosome Analysis and Precise Gender Determination

Through embryo biopsy, sex chromosomes are determined with complete accuracy. If the embryo carries XX chromosomes, it means the fetus is female. If it carries XY chromosomes, it means the fetus is male. Therefore, the doctor and laboratory can select an embryo of the desired gender based on medical results, provided there is more than one healthy embryo available for selection. This determination is made using highly advanced techniques such as DNA sequencing (NGS) or microarray, which are extremely precise and reliable techniques.

Is It Permissible to Use This Technique for Non-Medical Reasons?

In most Arab and Islamic countries, it is not permitted to use genetic testing of embryos (PGT) merely for selecting fetal gender, especially if there is no clear genetic disease that warrants it. This position reflects these countries' commitment to Islamic and ethical values. There are many important reasons why this procedure is not acceptable.

Islamic Principle and Interference with God's Creation

From a religious perspective, it is not permissible to interfere with God's creation without a clear and genuine medical need. God Almighty is the one who determines fetal gender, and human intervention in this without clear medical necessity is considered a transgression against God's wisdom. The Quran emphasizes that God is the one who grants males and females according to His wisdom, and it is not for humans to interfere in this without a legitimate reason.

Ethical and Humanitarian Considerations

From an ethical perspective, selecting a particular gender can lead to discrimination between males and females. This contradicts the fundamental principle of human equality. Additionally, there are concerns that selective abortion of a particular gender could lead to demographic imbalance in society, as has occurred in some Asian countries, causing long-term social and economic problems.

Legal and Legislative Considerations

From a legal perspective, using genetic testing to select gender is formally prohibited in some Arab countries. This reflects these countries' commitment to protecting embryos from arbitrary selection based on gender alone. Laws protect fetal rights and ensure that medical technologies are not used for illegitimate purposes.

When Is Genetic Testing Used to Determine Fetal Gender?

Genetic testing of embryos is used to determine fetal gender only in specific cases where there is a clear and genuine medical reason. These cases include:

Sex-Linked Genetic Diseases

There are several serious genetic diseases that are transmitted through the X chromosome and primarily affect males. Among the most famous of these diseases are: Duchenne muscular dystrophy (a very serious degenerative muscle disease), hemophilia (bleeding disorder), and Fragile X syndrome (a hereditary intellectual disability). In these cases, it is preferable to transfer a female embryo (XX) to reduce the risk of giving birth to a child affected by these serious diseases. This use is considered medically and religiously justified because it aims to protect the future child's health.

Avoiding Sex Chromosome Abnormalities

Some embryos may have an abnormal number of sex chromosomes, which can lead to numerous health problems. Turner syndrome (45,XO) affects females and causes short stature, infertility, and heart problems. Klinefelter syndrome (47,XXY) affects males and causes infertility, reduced fertility, and other problems. Genetic testing is used to exclude these embryos from transfer to avoid pregnancy with an embryo affected by a clear health problem. This use is also medically and religiously acceptable because it aims to prevent diseases and health problems.

Investigating Causes of Recurrent Miscarriage

Genetic testing may help determine whether there is a relationship between gender and previous pregnancy problems. In some cases, there may be genetic reasons related to gender that lead to recurrent miscarriage. In these cases, determining fetal gender may be helpful to avoid repeating these problems. This use is also considered medically justified if there is a clear medical reason.

Does Genetic Testing Guarantee Pregnancy with a Particular Gender?

No, even with genetic testing, it is not possible to guarantee with 100% certainty obtaining an embryo of the desired gender. There are several reasons for this:

Factors Affecting Results

Limited number of available embryos may mean there is no embryo of the desired gender. The possibility that none of the available embryos is of the desired gender. The possibility of embryo implantation failure despite genetic integrity, as other factors such as uterine quality and maternal health play an important role. However, in certain cases, genetic testing can increase the chances of pregnancy with an embryo of a particular gender if there is a clear medical need and a sufficient number of embryos are available.

Medical Ratios and Probabilities

The success rate of obtaining an embryo of a particular gender depends on several factors: number of available embryos, embryo quality, maternal age, and other health factors. On average, if there are 4-5 embryos available, the probability of having an embryo of the desired gender is relatively high. However, if there are only one or two embryos, it may not be possible to obtain the desired gender.

Conclusion

Although artificial insemination allows knowing fetal gender through genetic testing of embryos (PGT), selecting it merely for the desire to have male or female offspring is not a medically and religiously acceptable procedure in Islamic and Arab societies. Scientific methods exist, but they should only be used for legitimate and clear medical reasons. At Fertiliv IVF Center, we believe that every step of the treatment journey should be carefully planned and directed toward achieving pregnancy with health and safety, not to fulfill personal or cultural desires.
