Human genetic enhancement or human genetic engineering refers to human enhancement by means of a genetic modification. This could be done in order to cure diseases (gene therapy), prevent the possibility of getting a particular disease (similarly to vaccines), to improve athlete performance in sporting events (gene doping), or to change physical appearance, metabolism, and even improve physical capabilities and mental faculties such as memory and intelligence. These genetic enhancements may or may not be done in such a way that the change is heritable (which has raised concerns within the scientific community).

Genetics is the study of genes and inherited traits and while the ongoing advancements in this field have resulted in the advancement of healthcare at multiple levels, ethical considerations have become increasingly crucial especially alongside. Genetic engineering has always been a topic of moral debate among bioethicists. Even though the technological advancements in this field present exciting prospects for biomedical improvement, it also prompts the need for ethical, societal, and practical assessments to understand its impact on human biology, evolution, and the environment. Genetic testing, genetic engineering, and stem cell research are often discussed together due to the interrelated moral arguments surrounding these topics. The distinction between repairing genes and enhancing genes is a central idea in many moral debates surrounding genetic enhancement because some argue that repairing genes is morally permissible, but that genetic enhancement is not due to its potential to lead to social injustice through discriminatory eugenics initiatives.

Moral questions related to genetic testing are often related to duty to warn family members if an inherited disorder is discovered, how physicians should navigate patient autonomy and confidentiality with regard to genetic testing, the ethics of genetic discrimination, and the moral permissibility of using genetic testing to avoid causing seriously disabled persons to exist, such as through selective abortion.

The responsibility of public health professionals is to determine potential exposures and suggest testing for communicable diseases that require reporting. Public health professionals may encounter disclosure concerns if the extension of obligatory screening results in genetic abnormalities being classified as reportable conditions. Genetic data is personal and closely linked to a person's identity. Confidentiality concerns not only work, health care, and insurance coverage, but a family's whole genetic test results can be impacted. Affected individuals may also have their parents, children, siblings, sisters, and even extended relatives if the condition is either genetically dominant or carried by them. Moreover, a person's decisions could change their entire life depending on the outcome of a genetic test. Results of genetic testing may need to be disclosed in all facets of a person's life.

Non-invasive prenatal testing (NIPT) can accurately determine the sex of the fetus at an early stage of gestation, raising concerns about the potential facilitation of sex-selective termination of pregnancy (TOP) due to its ease, timing, and precision. Even though the ultrasound technology can do the same, NIPT is being explored due to its capability to accurately identify the fetus's sex at an early stage in pregnancy, with increasing precision as early as 7 weeks' gestation. This timeframe precedes the typical timing for other sex determination techniques, such as ultrasound or chorionic villus sampling (CVS). The high early accuracy of NIPT reduces the uncertainty associated with other methods, such as the aforementioned, leading to more informed decisions and eliminating the risk of inaccurate results that could influence decision-making regarding sex-selective TOP. Additionally, NIPT enables sex-selective TOP in the first trimester, which is more practical, and allows pregnant women to postpone maternal-fetal bonding. These considerations may significantly facilitate the pursuit of sex-selective TOP when NIPT is utilized. Therefore, it is crucial to examine these ethical concerns within the framework of NIPT adoption.

Ethical issues related to gene therapy and human genetic enhancement concern the medical risks and benefits of the therapy, the duty to use the procedures to prevent suffering, reproductive freedom in genetic choices, and the morality of practicing positive genetics, which includes attempts to improve normal functions.

In every genetic based study conducted for humanity, studies must be carried out in accordance with the ethics committee approval statement, ethical, legal norms and human morality. CAR T cell therapy, which is intended to be a new treatment aims to change the genetics of T cells and transform immune system cells that do not recognize cancer into cells that recognize and fight cancer. it works with the T cell therapy method, which is arranged with palindromic repeats at certain short intervals called CRISPR.

All research involving human subjects in healthcare settings must be registered in a public database before the recruitment of the first trial. The informed consent statement should include adequate information about possible conflicts of interest, the expected benefits of the study, its potential risks, and other issues related to the discomfort it may involve.
