Background: Chorionic Villus Sampling was introduced in Nigeria because of the large population affected by the sickle cell gene. Previous studies examined some selected sociodemographic characteristics of the clients. There is the need to determine their impact on the utilization of the service.

Objective: To describe the sociodemographic characteristics of chorionic villus sampling clients and their influence on the utilization of the service. The genotypes of the fetuses are also determined.

Patients and Method: Two hundred and twenty two clients had chorionic villus sampling from 1 January 2001 to 31 December 2003. One hundred and seventy seven had complete data that was analysis retrospectively. Genotype results were obtained in 157 clients. Epi- info statistical package was used for data analysis.

Results: The mean age of the clients was 31.3 ± 4.8 years and the mean parity was 3.8 ± 1.7. Halve of them had no previously affected child. The dominant religion was Christianity (83.6%) and most of them (74.8%) had completed secondary education. The bulk (98.9%) of the clients were in the high socioeconomic group. The Yoruba tribe constituted the bulk (62.7%) of the clients. Most (68.4%) received information through health workers or clinics. The commonest genotype is AS (47.1%).

Conclusion: There is a class bias in the utilization of the service. A re-evaluation of information dissemination strategy especially through the mass media is needed to reach out to the majority of clients who need the service.
