Genetic Testing and Gender Selection: Religious and Ethical Perspectives

With advances in reproductive medicine and modern technologies, it has become possible to determine fetal gender before implantation using genetic testing of embryos such as PGT-A and PGT-M. These advanced techniques have opened the door for couples to select embryos based on their chromosomal health, including determining whether the embryo is male or female. However, this medical capability has raised profound ethical and religious questions: Is it permissible to use this information to select embryos of a particular gender? Is this an unjustified interference with God's creation? Can it be justified medically or ethically? In this comprehensive article, we will highlight the role of genetic testing in determining fetal gender and its impact on couples' decisions, while providing a balanced perspective from both religious and ethical standpoints.

How Genetic Testing Determines Fetal Gender

When performing genetic testing of embryos (PGT), the chromosomal structure of each embryo is analyzed with extremely high precision. Through this testing, the presence of normal sex chromosomes (XX for females and XY for males) or abnormalities such as (45,XO) or (47,XXY) can be detected. This testing provides doctors and couples with highly accurate information about the embryo's condition before transfer to the uterus. However, the most important question that arises is: Is this testing used only to determine gender? And is it permissible to use it to select an embryo based on gender alone?

Chromosomal Structure and Gender Differences

Sex chromosomes are what determine fetal gender. Females have a pair of X chromosomes (XX), while males have one X chromosome and one Y chromosome (XY). Modern genetic testing can determine this with accuracy reaching 99%. Additionally, sex-linked chromosomal abnormalities can be detected, such as Turner syndrome (45,XO) affecting females or Klinefelter syndrome (47,XXY) affecting males.

Using Genetic Testing to Determine Gender for Legitimate Medical Reasons

There are legitimate and necessary medical uses for genetic testing to determine fetal gender, and these uses are acceptable from religious, ethical, and medical perspectives.

Avoiding Sex-Linked Genetic Diseases

There are several serious hereditary diseases that are transmitted through the X chromosome and primarily affect males. Among the most famous of these diseases are: hemophilia (bleeding disorder), Duchenne muscular dystrophy (a serious degenerative muscle disease), and Fragile X syndrome (a hereditary intellectual disability). In these cases, selection of female embryos (XX) may be recommended to prevent disease transmission to the child, as females are usually carriers of the gene without developing the disease themselves. This use is considered medically and religiously justified because it aims to protect the future child's health.

Diagnosing 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.

Using Genetic Testing to Select Gender for Non-Medical Reasons

Although the original and true purpose of genetic testing is embryo health and prevention of hereditary diseases, some couples seek to use this technology to select fetal gender for personal, cultural, or psychological reasons. These motivations may include the desire of parents to have a child of a particular type, the family's desire to balance the number of males and females, or social and cultural pressures. This use is ethically unacceptable and is not permitted in most Islamic and developed countries because it does not serve a clear and legitimate medical purpose. At Fertiliv IVF Center, we are committed to the ethical and religious use of genetic testing only.

Religious Perspective: Is It Permissible to Use Genetic Testing to Select Fetal Gender?

Islamic law provides a clear framework for understanding whether the use of these techniques is permitted. Let us review the religious opinions in detail.

Scholars' Position on IVF in General

The vast majority of Muslim scholars view that resorting to IVF and its techniques when needed to treat infertility is permissible, provided that the eggs and sperm come only from the couple and that neither is replaced with an external source. This consensus reflects a deep understanding that medical treatment for infertility is permitted in Islam and is even recommended when the goal is to achieve a Muslim family.

Religious Opinion on Using Genetic Testing to Determine Gender

If the purpose of genetic testing is to prevent hereditary diseases or preserve fetal health, the vast majority of scholars consider it permissible. This opinion is based on the principle of "necessity permits the prohibited" and the principle of preserving life and health, which are fundamental Islamic objectives. However, if the purpose is to discriminate between embryos based on gender alone without a clear medical reason, the religious opinion tends toward non-permissibility because it is considered interference with God's creation without genuine medical necessity.

Religious Warnings Against Random Gender Selection

Some respected scholars have said that selecting gender without a legitimate medical reason is religiously impermissible because it resembles the "deliberate selection" that existed in pre-Islamic times, when some chose males over females. The Quran strongly condemns this behavior and considers it a major sin. Therefore, any attempt to select a particular gender without a legitimate medical reason is considered a return to those condemned pre-Islamic practices.

Ethical Perspective: Is It Permissible to Discard an Embryo Because of Its Gender?

From an ethical and humanitarian perspective, there are several aspects we must consider when examining the issue of fetal gender selection.

The Human Aspect and Respect for Potential Life

The embryo, even if not yet implanted in the uterus, is treated in many modern ethical theories as potential life deserving of respect and protection. Therefore, excluding or discarding it based on gender alone constitutes unjustified discrimination and a violation of the rights of this potential life. This ethical principle applies particularly when there is no clear and legitimate medical reason for discarding the embryo.

The Social Aspect and Demographic Balance

Repeated resort to selecting a particular gender leads to disruption of the male-to-female ratio in society. This has actually occurred in some Asian countries as a result of selective abortion of females, leading to long-term social and economic crises. When there is a shortage of females, there is an increase in spinsterhood rates and other social problems. This illustrates that gender selection is not merely a personal matter but has far-reaching social effects.

The Psychological Aspect for Parents and Child

Some couples feel sadness or frustration if the embryo is not of the gender they expected. However, it must be clearly understood that a healthy embryo is the highest and greatest goal, not the gender. A child born in good health, whether male or female, is a blessing from God deserving gratitude and appreciation. Additionally, psychological studies suggest that children selected for their gender may later feel psychological pressure to meet the expectations their parents have placed on them.

Legal Perspectives Around the World

Laws and regulations around the world differ on the issue of fetal gender selection. Let us review the different legal frameworks.

In Many Arab and Islamic Countries

Genetic testing of embryos is permitted for medical purposes only, especially to prevent hereditary diseases and chromosomal abnormalities. Use of the test to determine or select gender for personal or cultural reasons is completely prohibited. This position reflects these countries' commitment to Islamic and ethical values.

In Some Western Countries

Gender determination for medical reasons only is permitted in most Western countries. For personal reasons, it may be permitted in some Western countries, but it remains ethically and legally controversial. There are ongoing discussions about whether gender selection for personal reasons should be allowed.

When Is Genetic Testing for Gender Considered Ethically and Religiously Acceptable?

There are clear criteria by which we can determine whether using genetic testing to determine gender is acceptable.

Acceptable Cases

Genetic testing to determine gender is considered acceptable when there is a sex-linked genetic disease and the test is used to prevent the birth of an affected child. It is also considered acceptable to prevent sex chromosome abnormalities that may lead to serious future health problems. Additionally, interpretation of results should be done by the treating physician to make an accurate medical decision, not solely based on parental wishes.

Unacceptable Cases

Genetic testing is unacceptable when used to reject an embryo based on gender alone without a clear and legitimate medical reason. It is also unacceptable to prefer one gender over another based on cultural, social, or personal criteria. Additionally, it is considered unacceptable to conceal information from doctors or exploit results for non-medical decisions.

Conclusion

Genetic testing of embryos is not merely a tool for determining gender but rather an advanced and valuable medical means for improving the chances of successful pregnancy and preventing serious hereditary diseases. However, using it to select a particular gender for non-medical reasons is disputed religiously and ethically and is rejected in most Islamic and Arab cultures. It is very important that the focus remains on fetal health and disease prevention, not on gender. A child born in good health, whether male or female, is a blessing from God deserving welcome, love, and care. At Fertiliv IVF Center, we believe that genetic testing should always aim to preserve reproductive health and prevent hereditary diseases, not to prefer one gender over another.
