What you need to know about Co-Sy IVF

We offer Conventional as well as Minimal stimulation IVF, this is because not all women will respond the same way to a particular stimulation protocol. The conventional protocol is ideal for women who are good responders because one harvest will yield an adequate number of eggs/embryos for a high cumulative pregnancy rate.

We have infertility specialist partners in various provinces in central and
northern Luzon who can perform the ovarian hyper-stimulation and monitoring in your locality. This means that if you live far from the center, the process will be less taxing on you because you only need to come to Angeles City during the oocyte retrieval and embryo transfer procedures.Surgical sperm retrievals are also performed in the center in cases of severe male factor.

Because you are being managed by only one clinician, he/she knows your
history very well and he/she will be able to tailor-fit the management to your
particular needs. The same doctor who performs your stimulation, will also be the same one performing your egg retrieval as well as your embryo transfer in our center.

Personalized treatment at its best

If the first transfer resulted in a live birth, you can have another frozen embryo transfer in order to have a second or third baby and complete your desired family size from a single harvest.

If the first transfer is not successful, you don’t have to go through the same procedure again, just the embryo transfer, until you achieve a pregnancy. Frozen embryo transfers are associated with equal if not better pregnancy rates as fresh transfers, at a fraction of the cost. Poor responders, on the other hand, will benefit more from minimal stimulation but harvesting twice in order to minimize the cost but improve the comfort of the patient as well as the outcome.
