The importance of on-site genetic counseling for prospective assisted reproductive technology patients.

ABSTRACT

PURPOSE: To assess the value of having an onsite genetic counseling service integrated into an assisted reproductive technology (ART) center. METHODS: Since January 2021, we have offered genetic counseling at our ART center for couples whose medical history suggests risk of transmission of a genetic disorder. The percentage of couples referred for genetic counseling, the distribution of couples according to reasons for consultation, the mode of transmission in cases of Mendelian disorders, and the frequency of mutations for those with identified genetic disorders were determined. RESULTS: In an 18-month period, 150 of 1340 couples (11.2%) enrolled for ART treatment were referred to the genetic counseling unit. Two-thirds (99/150, 66.0%) were referred for a known genetic risk, a family history of a genetic disorder or chromosomal abnormality, a serious condition of unknown cause, or consanguinity. The remaining couples had a putative genetic risk (diminished ovarian reserve, high incidence of oocyte immaturity, recurrent abortion, or severe male infertility). Of the 99 with known genetic risk, 62 (62.7%), were approved for ART treatment, 23 (23.2%) were recommended prenatal or preimplantation testing, and 14 (14.1%) were referred for further testing before undergoing ART. CONCLUSIONS: Our findings reveal great value in having an on-site genetic counseling unit for referral of ART patients. Such a unit makes the ART process smoother and safer for couples, and it lightens the burden of ART staff by removing responsibilities for which they are neither trained, nor should they have to assume.
