In Vitro Fertilization Results

Dr A. Sõritsa’s team performed the first in vitro fertilization procedure in 1993 at the Women’s Clinic of the University of Tartu. The first child was born in August 1995. To date, over 2,500 children have been born as a result of our team’s work.

Below are brief explanations of the abbreviations used in the table. Pisut pikemalt samadest asjadest Viljatuse lehekülje kunstliku viljastamise allosas.

• Follicular Puncture (FP) – A procedure involving the penetration of mature follicles (fluid-filled sacs in which the egg develops, attached to the follicular wall) using a long, fine aspiration needle under ultrasound guidance. These follicles have developed and matured following superovulation induced by medication. The follicular fluid containing the mature oocyte is then aspirated into a sterile test tube using vacuum suction. In the laboratory, the oocytes are isolated, washed, and cleansed of excess surrounding support cells.
• Embryo Transfer (ET) – The process of transferring a developing embryo, formed after successful fertilization of the oocyte retrieved during follicular puncture, into the woman’s uterine cavity. This is performed using a thin plastic catheter through which a small volume of culture medium containing the embryo(s) is gently injected into the uterus.
• Transfer of Frozen/Thawed Embryos – The transfer of embryos into the uterus after thawing. These embryos were previously obtained through in vitro fertilization of oocytes retrieved during an earlier follicular puncture and then cryopreserved.
• IVF- ET  (In Vitro Fertilisation – Embryo Transfer) – The transfer of embryos into the uterus that were obtained via standard in vitro fertilization procedures.
• ICSI -ET (Intracytoplasmic Sperm Injection – Embryo Transfer) – The transfer of embryos into the uterus that were created by injecting a single sperm directly into an oocyte.
• ET Pregnancy Rate (%) – The percentage of clinical pregnancies resulting from embryo transfers. A clinical pregnancy is confirmed by a positive blood test for human chorionic gonadotropin (hCG) and ultrasound confirmation of an implanted embryo. Note: Not all clinical pregnancies continue to term, similar to naturally conceived pregnancies.
• FP Pregnancy Rate (%) – The percentage of clinical pregnancies in relation to the number of follicular puncture procedures performed.
• Recipient -ET – Embryo transfer to a recipient woman using embryos derived from donor oocytes.

To fulfill our legally mandated reporting obligations, we kindly ask patients who become pregnant as a result of infertility treatment or in vitro fertilization to inform their treating physician about the delivery, its course, and the health status of the newborn.
