Excerpt from the Oak Clinic Infertility Blog

Comparison of HCG and Agonist as Trigger for Oocyte Maturation -Fertility and Sterility Vol.102, No.3, September 2014-

In this paper, we look backwards to see if there is a significant difference in the rate of fetal congenital malformations and the frequency of problems related to pregnancy and childbirth between groups that use HCG and agonists to trigger egg maturation when collecting eggs in the stimulation cycle.
The results of the investigation are shown. As expected, there was no difference between the two groups.
We mainly use agonists as triggers to avoid ovarian hyperstimulation syndrome in almost all patients who live far away and are checked for follicle size at a nearby medical institution.
With this report that there is no adverse effect on the fetus and mother, we can provide the current protocol with even more peace of mind. (Excerpt)


Patient Testimonial

❖After IVF with ICSI, I finally became pregnant.
There were still troubles ahead though, as bleeding led to me being hospitalized three times due to an imminent miscarriage.
Sometimes I thought my goal was impossible, but finally my time with Oak Clinic ended and my baby was born healthy. We did it!
I am deeply grateful to the doctors, nurses, cleaners, cooks, staff, and many others of Oak Sumiyoshi Obstetrics and Gynecology.
I couldn't get this joy without going to Oak. I'm really thankful to you.

As a result, gynecological surgery and infertility treatment can be performed at our hospital, and patients can proceed with treatment with peace of mind. Therefore, the medical office, nursing department, and lab are working to deepen teamwork even more than before.

Let's do our best together so that we can have as many children as possible as soon as possible.
