Preconceptional Sex Selection Techniques

Number: 0323


Aetna considers preconceptional sex selection techniques for enriching sperm samples for X spermatozoa medically necessary only when used to prevent the conception and birth of a male child to a woman who is known to be heterozygous for a seriously handicapping X-linked condition (e.g., Lesch-Nyhan disease).

Assisted reproductive techniques, including in-vitro fertilization (IVF) or intra-cytoplasmic sperm injection (ICSI) are not considered treatment of disease when the sole indication for the procedure is sex selection and not to prevent birth of child with a seriously handicapping genetic defect.

Note: The option of various post-sperm sorting infertility services (e.g., intra-uterine insemination, IVF, gamete intra-fallopian transfer [GIFT]) may be restricted depending upon the member's specific plan benefits.  Aetna provides coverage for IVF and other assisted reproductive technologies (ART) to treat infertility, where required by state mandate and when the member's plan provides for such coverage.  Please check benefit plan descriptions for details.

Primary sex selection (i.e., prior to fertilization using sperm sorting) has been suggested as an alternative to secondary sex selection (i.e., conception followed by prenatal diagnosis and abortion of affected fetuses) in couples known to be at increased risk for specific, detectable, heritable disorders.  Preconceptional sex selection techniques have been proposed as a mechanism to minimize the risk of transmission of sex-linked diseases to potential offspring and are accomplished by differential sorting of X- and Y-bearing sperm using filtration and/or flow cytometry.

Sperm sorting techniques have been reported to result in samples enriched for X- or Y-bearing spermatozoa to levels as great as 75 %.  Although preconceptional sex selection through sperm sorting increases the likelihood of male or female offspring, it does not guarantee the sex of the fetus.  Therefore, when medically indicated, invasive prenatal diagnostic procedures to confirm the sex of the fetus should be offered to the patient utilizing preconceptional sex selection techniques.

The American College of Obstetricians and Gynecologists Committee on Ethics (ACOG, 2007) presented various ethical considerations and arguments relevant to both pre-fertilization and post-fertilization techniques for sex selection.  The principal medical reason for sex selection is known or suspected risk of sex-linked genetic disorders.  Other reasons sex selection is requested are personal, social, or cultural in nature.  The Committee on Ethics supports the practice of offering patients procedures for the purpose of preventing serious sex-linked genetic diseases.  However, the committee opposes meeting requests for sex selection for personal and family reasons, including family balancing, because of the concern that such requests may ultimately support sexist practices.  Because a patient is entitled to obtain personal medical information, including information about the sex of her fetus, it will sometimes be impossible for health care professionals to avoid unwitting participation in sex selection.
