How voluntary prenatal diagnosis and selective abortion increase the abnormal human gene pool

Area of Science:

• Genetics
• Bioethics
• Public Health

Background:

• Prenatal diagnosis allows for the identification of genetic disorders in fetuses.
• Selective abortion of affected fetuses is often perceived as a eugenic practice.
• Voluntary programs are currently the standard for prenatal genetic screening.

Purpose of the Study:

• To evaluate the eugenic impact of current voluntary prenatal diagnosis and selective abortion programs.
• To analyze the effect of these programs on the prevalence of deleterious genes.
• To discuss the ethical implications of parental choice and societal pressures in genetic screening.

Main Methods:

• Analysis of genetic population dynamics.
• Review of current prenatal screening protocols.
• Ethical framework assessment of reproductive autonomy.

Main Results:

• Voluntary prenatal diagnosis and selective abortion may inadvertently increase the frequency of deleterious genes in the population.
• Mandatory selective abortion of affected fetuses and carriers could reduce gene pool defects.
• The current system raises concerns about informed consent and coercion.

Conclusions:

• Current voluntary prenatal screening and abortion practices may not yield the expected positive eugenic outcomes.
• Societal pressures and the concept of "freedom of choice" complicate the ethics of prenatal genetic interventions.
• Further research is needed to understand the long-term genetic and societal consequences.
