Regulatory safeguards needed if preimplantation genetic testing for polygenic risk scores (PGT-P) is permitted in Singapore.

Singapore, a highly affluent island city-state located in Southeast Asia, has increasingly leveraged new assisted reproductive technologies (ART) to overcome its dismal fertility rates in recent years. A new frontier in ART is preimplantation genetic testing (PGT) for polygenic risk scores (PRS) to predict complex multifactorial traits in IVF (in vitro fertilisation) embryos, such as type 2 diabetes, cardiovascular diseases and various other characteristics like height, intelligence quotient (IQ), hair and eye colour. Unlike well-known safety risks with human genome editing, there are negligible risks with PGT-P, because there are no man-made genetic modifications that can be transmitted to future generations. Nevertheless, the current efficacy of using PGT-P to select IVF embryos for either increased or decreased probability of developing specific polygenic traits is still far from certain. Hence, the regulatory safeguards proposed here will be based on the assumption that the efficacy of this new technology platform has already been validated. These include: (1) restricting the application of PGT-P only for prevention of clinically relevant polygenic disease traits, (2) securely blocking patients' access to the raw genomic DNA sequencing data of their IVF embryos, (3) validating diagnosis of polygenic disease traits in the prospective parents/grandparents of IVF embryos, and restricting PGT-P only for preventing specifically diagnosed polygenic disease traits and (4) mandating rigorous and comprehensive genetic counselling for IVF patients considering PGT-P. There is an urgent and dire need to prevent abuse of the PGT-P technique, as well as protect the interests and welfare of patients if its clinical application is to be permitted in the country.

Islamic Viewpoints on Opportunistic Sex Selection of IVF Embryos upon doing Preimplantation Genetic Testing for Preventing Genetic Diseases.

In recent years, preimplantation genetic testing (PGT) of IVF embryos have gained much traction in clinical assisted reproduction for preventing various genetic defects, including Down syndrome. However, such genetic tests inevitably reveal the sex of IVF embryos by identifying the sex (X and Y) chromosomes. In many countries with less stringent IVF regulations, information on the sex of embryos that are tested to be genetically normal is readily shared with patients. This would thus present Muslim patients with unintended opportunities for sex selection based on personal or social biases without any pressing need or valid medical reason. Additionally, there are other patients who claim using PGT for preventing genetic defects as a pretext or "convenient excuse," with a secret intention to do sex selection when it is banned in their home country. Currently, non-medical sex selection is a highly-controversial and hotly debated issue in Islam, because there is generally a strong preference for having sons over daughters due to widespread cultural norms of elderly parents depending on their sons for financial support, as well as the need for male heirs to continue the family lineage within the backdrop of local patriarchal cultures. There is a risk of gender imbalance and social disequilibrium occurring in Islamic societies due to prevalent sex selection. Hence, the question is whether opportunistic sex selection with PGT would contravene Islamic ethics and principles, which will thus be discussed here.

Sex Reassignment Surgery, Marriage, and Reproductive Rights of Intersex and Transgender People in Sunni Islam.

The traditional gender binary constitutes an integral aspect of Islamic social ethics, which has a pivotal role in shaping religious obligations, legal proceedings, and interpersonal judgments within Muslim communities. Within the familial sphere, this gender binary underscores fundamental responsibilities encompassing parenthood, filial duties, and inheritance rights. Recent years have witnessed a growing challenge to the traditional concept of the gender binary within Islamic societies. This shift is driven by increasing social libertarianism that emphasizes gender fluidity and individual choice. Hence, this article aims to critically scrutinize evolving discussions and controversies about the rights of intersex and transgender individuals, particularly issues relating to sex reassignment or gender-affirming surgery, marriage, and reproduction, from the perspective of the Sunni tradition of Islam. To support the various interpretations and insights presented here, a comprehensive and rigorous analysis is carried out on various religious texts and scholarly sources to elucidate the theological and jurisprudential positions on gender issues. It is thus concluded that Shariah offers greater flexibility in the treatment of intersex individuals compared to those with gender dysphoria because the intersex condition is viewed as a physical impairment that is not the choice of the afflicted individual. By contrast, in the case of individuals with gender dysphoria, they are willfully attempting to change their recognized biological sex, that God had naturally given to them at birth. Therefore, it is recommended that such transgender individuals deserve respectful psychological and social rehabilitation with help and guidance from religious authorities, their families, and communities.

An Ethico-Legal Analysis of Artificial Womb Technology and Extracorporeal Gestation Based on Islamic Legal Maxims.

Artificial womb technology for extracorporeal gestation of human offspring (ectogenesis or ectogestation) has profound ethical, sociological and religious implications for Muslim communities. In this article we examine the usage of the technology through the lens of Islamic ethico-legal frameworks specifically the legal maxims (al-Qawaid al-Fiqhiyyah) and higher objectives of Islamic law (Maqasid al-Shariah). Our analysis suggests that its application may be contingently permissible (halal) in situations of dire need such as sustaining life and development of extremely premature newborns, for advancing fetal medicine and avoiding maternal co-morbidities during fetal treatment, and for enabling motherhood for women without functional wombs, or who face grave medical risks in pregnancy. However, its application may be proscribed (haram) for enabling healthy women to avoid pregnancy and childbirth, or to achieve parenthood equity. Specification of these views to particular policy, legal contexts and Fatwa will require multidisciplinary Shariah-based bioethical deliberations between jurists, policymakers, and scientists.

Islamic Perspectives on Elective Ovarian Tissue Freezing by Single Women for Non-medical or Social Reasons.

Non-medical or Social egg freezing (oocyte cryopreservation) is currently a controversial topic in Islam, with contradictory fatwas being issued in different Muslim countries. While Islamic authorities in Egypt permit the procedure, fatwas issued in Malaysia have banned single Muslim women from freezing their unfertilized eggs (vitrified oocytes) to be used later in marriage. The underlying principles of the Malaysian fatwas are that (i) sperm and egg cells produced before marriage, should not be used during marriage to conceive a child; (ii) extraction of mature egg cells from single women being unacceptable; and (iii) fertility preservation in anticipation of late marriage is a conjecture that has not yet occurred. Ovarian tissue freezing can potentially be a more Shariah-compliant alternative to social egg freezing, because once the frozen ovarian cortical tissue sections have been re-transplanted back into the woman, mature egg cells can readily be produced, collected, and fertilized by the husband's sperm only during the period of marriage contract ('akd al-nikah). Unlike accidental mix-ups with frozen eggs, muddling of lineage (nasab) would be automatically avoided in ovarian tissue freezing due to immunological rejection. However, upon critical analysis based on Qawa'id Fiqhiyyah (Islamic Legal Maxims), Maqasid-al-Shariah (Higher Objectives of Islamic Law), and Maslahah-Mafsadah (benefits versus harmful effects on society), elective ovarian tissue freezing by healthy single women for social reasons would likely be a highly contentious and controversial issue within Muslim communities that may conflict with conservative social-religious norms. This thus needs further debate among Islamic jurists in dialogue with medical doctors and biomedical scientists.

Islamic Jurisprudence on Harm Versus Harm Scenarios in Medical Confidentiality.

Although medical confidentiality is widely recognized as an essential principle in the therapeutic relationship, its systematic and coherent practice has been an ethically challenging duty upon healthcare providers due to various concerns of clinical, moral, religious, social, ethical and legal natures. Medical confidentiality can be breached to protect the patient and/or others if maintaining confidentiality causes serious harm. Healthcare professionals may encounter complicated situations whereby the divulgence of a patient's confidential information may pose a threat to one party whereas the concealment of such information may cause harm to another. After deliberating on the Islamic concept of harm (darar), this paper focuses on the dual duty and conflicts of interests faced by healthcare professionals in the practice of medical confidentiality. Referring to serious infectious diseases with a special mention of AIDS, this study also provides discourse on how healthcare professionals deal with difficult scenarios of conflicts of interests and ethical dilemmas.

Medical Confidentiality Ethics: The Genesis of an Islamic Juristic Perspective.

The Shari'ah affords considerable concern for human emotions, with its rulings seeking to remove the deliberate and accidental types of harm that may be inflicted on individuals or society. The principle of medical confidentiality protects patients' dignity and avoids potential harm if otherwise practised. Texts from the Quran and Sunnah substantiate that unjustified disclosure of secrets is prohibited and whoever breaches confidentiality is to be punished. This paper explores the origins of Islamic ethical framework vis-à-vis dealing with privacy, particularly confidential information acquired by health professionals. For that, this paper attempts to explore various ayat (Quranic verses) and ahadith (Prophetic traditions) related to privacy, and thus to analogically deduct various aspects of confidentiality in the context of medical ethics. As a result, it aims to discourse on key principles of medical confidentiality from an Islamic juristic perspective, discussing its types and conditions.
