“I am honored to be the one to share the first days of the magical development of the human embryos. Their very existence compels me to diligently carry out the challenging task of caring for them with the utmost precision and enthusiasm. I have found and pursued my passion.”
Dr. Esterhuizen has been active in this field for the past 30 years. Prior to joining Mississippi Reproductive Medicine in September 2014, she was the Laboratory Director at Medfem Clinic in Bryanston, currently the largest Assisted Reproductive Technology (ART) Unit in South Africa.
Dr. Esterhuizen completed her Ph.D. thesis entitled, Evaluation of Gamete Dysfunction as a Cause of Failed Human in Vitro Fertilization in the Department of Obstetrics & Gynecology, Stellenbosch University, South Africa in 2000. Through the years she became a specialist in male diagnostic testing and as a result, has improved the management of infertile males in various reproductive units. Her studies and the outcome thereof have been referenced in several national and international presentations by her colleagues (Belgium, India and The Sudan). Her studies have been published in several internationally recognized peer journals such as Andrologia, Journal of Assisted Reproductive Genetics, Human Reproduction, Molecular Andrology and the Journal of in Vitro Fertilization and Embryo Transfer.
She was part of the educational team in the Semenology Workshop for Sub-Saharan Africa Scientists, Tygerberg, Cape Town in September 1998 and the Semenology Workshop in Khartoum, The Sudan in 2011.
Dr. Esterhuizen successfully performed the first known micromanipulation technique (1993) on human oocytes in South Africa resulting in a live birth. She was the first in Africa to successfully perform embryo biopsies on human embryos and Preimplantation Genetic Screening using FISH, resulting in live births in 1998. She was one of the team members who performed the first oocyte cryopreservation in South Africa in 2008 which consequently resulted in a live birth. She developed and employed several sperm tests which are used by pathology laboratories and private IVF practices in South Africa as part of routine semen analysis and for additional diagnostic testing.

In order to receive CAP accreditation, a laboratory must demonstrate that it operates with the highest standards of quality, accuracy and consistency. The CAP inspection process investigates several components of the laboratory: assay validation data, quality management program, sample tracking procedures, lab personnel qualifications, facilities, safety, and having a lab that is compliant and ready for inspection. The CAP Laboratory Accreditation Process is an internationally recognized program designed to help clinical labs achieve excellence beyond that which is required for regulatory compliance.
