Minimal Stimulation IVF is an in vitro fertilization method that uses lower hormone doses than conventional IVF. The goal is to stimulate the ovaries more naturally, producing a sufficient number of high-quality eggs.

This method is more comfortable for patients, reduces the risk of side effects, is cost-efficient and is very suitable for patients who prioritize a minimally invasive approach with effective results.

In Minimal Stimulation IVF, ovarian stimulation begins with oral medication and low-dose hormone injections to stimulate follicle growth on the third day of the menstrual cycle. Further monitoring is performed through ultrasound and hormone examinations. Once the follicles show optimal development, GnRH agonists are administered to stimulate egg maturation.

We recommend the first appointment on the third day of the menstrual cycle. At the first appointment, the patient will undergo a fertility medical consultation, which will include a medical history review and an initial evaluation of reproductive status. The examination will then include a transvaginal ultrasound to assess the condition of the uterus and ovaries, a hormone test to evaluate overall hormonal function, and a semen analysis.

All examination results will be the basis for planning a fertility program that suits the patient's needs and condition.

We recommend that patients bring the results of previous ultrasound examinations, laboratory tests, semen analysis, and clinical summaries regarding fertility status.

Yes, the sex of the embryo can be identified through Preimplantation Genetic Testing for Aneuploidies (PGT-A) .

Embryo sex selection can be done based on medical indications.

Some fertility laboratory tests do not need to be repeated if they were performed within the previous 6 months to 1 year. However, for hormones whose levels fluctuate during the menstrual cycle—such as FSH, LH, estradiol, and progesterone—tests should be repeated at specific times during the menstrual cycle to evaluate fertility status and determine treatment options.

Yes, the OPU procedure at Kato Ojin IVF Center can be performed without anesthesia and without hospitalization. The OPU procedure uses a special, small needle designed to minimize tissue trauma, minimize pain, and lower the risk of bleeding and complications. Because the procedure does not require anesthesia, patients remain conscious and can go home immediately afterward, eliminating the need for hospitalization. With minimal pain and side effects, patients can feel more at ease and confident about undergoing the IVF process.

Yes, pregnancy can be achieved through IVF.

The pregnancy program at Kato Ojin IVF Center carries out a minimal stimulation protocol using low-dose fertility drugs that are proven effective and have been implemented for more than 30 years at Kato Ladies Clinic branches in various countries.

The Kato Ojin IVF Center's medical and laboratory teams have received training from the Kato Ladies Clinic in Japan. The embryo laboratory meets clean room standards and is equipped with globally standardized IVF equipment in the field of assisted reproductive technology.

The procedure is more comfortable for the patient, does not require anesthesia and hospitalization, and is more cost-efficient without reducing the effectiveness of the program.

The protocol used has been shown to have a high success rate with a very low risk of ovarian hyperstimulation.
