Welcome to Beloved Fertility Center by Dr. Suchada Mongkolchaipak, Phyathai Sriracha Hospital, Thailand

With more than 16 years of advanced fertility care, Beloved Fertility Center is the fertility clinic’s trusted source in developing precise fertility treatment option that consistently lead to high success rates.

All our fertility doctors are fellowship-trained, board-certified reproductive endocrinologists. In fact, Beloved Fertility Center is the only private setting in Thailand where is the training center for fellowship in reproductive medicine. Our success rates continue to be higher every year and higher than the national average.

Our IVF Success Rates

IVF cycles that took place in the current calendar year will be released in the report in two years’ time to account for births because it takes a period of time to finish the treatment cycle and to wait for the success of a complete delivery.

Disclaimer: A comparison of clinic success rates may not be meaningful because patient medical characteristics, treatment approaches, and entrance criteria for ART may vary from clinic to clinic. www.sart.org

Implantation rate

Implantation rate means a positive hCG of more than 100 mIU/ml after 14 days of embryo transfer. The implantation rate is defined as a positive pregnancy test the blood tests performed per transferred embryos, which includes both viable and nonviable pregnancies evaluated by ultrasound.

Implantation rate per embryo transfer is calculated by the number of patients who have positive hCG of more than 100 mIU/ml 14 days after transfer divided by the number of transferred patients.

Once positive blood for hCG more than 100 mIU/ml 14 days after embryo transfer, we will continue to check the increase in hCG levels for a while to monitor the growth of the embryos. The best time to evaluate the viability of the pregnancy using ultrasound is at about 7–8 weeks’ gestation. Some implanted pregnancies may end up with a fall in hCG level and some may end up with the pregnancy being evaluated as nonviable.

Our implantation rate including all age groups and all types of patients in 2015 was 57% per embryo transfer. This is the average rate for all cases, including those with good prognosis and difficult cases. It is one of the earliest parameters that we can use to monitor quality control in the IVF laboratory. If the rates drop significantly this should trigger a thorough evaluation of the entire IVF system. A weakness somewhere in the system (in the lab or elsewhere) will cause implantation rates to drop as embryos become weaker with a decreased ability to implant.

Implantation rate can also vary due to the number of transferred embryos. If we transfer too many embryos, the implantation rate would be higher but the live birth rate than that of the transfer of fewer embryos, due to the complications of abortion and preterm labor. In some situations, in which some doctors use hCG for luteal support and create a false positive pregnancy test from the medication, hCG levels will be low and drop spontaneously and never rise beyond the stage of creating a gestational sac.

Clinical pregnancy rate

Clinical pregnancy rate per egg retrieval is calculated by the number of patients who have evidence of a viable pregnancy by ultrasound divided by the number of egg-retrieval retrieval cycles.  Term ‘clinical pregnancy’ is used when a viable pregnancy is detected on the day of the ultrasound evaluation.

Pregnancy rate per egg retrieval may involve more than one transfer procedure until the embryos in that cycle are finished or pregnancy is achieved. ‘Clinical pregnancy rate’ means a pregnancy that can develop until the stage of gestational sac production and there is evidence of pregnancy with a live baby. Some clinical pregnancies might result in early fetal death during weeks 8 to 12. If the clinical pregnancy develops beyond 12 weeks of pregnancy, we call this an ongoing pregnancy.

Ongoing pregnancy rate

The ongoing pregnancy rate is a pregnancy diagnosed by ultrasonographic visualization of one or more gestational sacs with a viable fetus or definitive clinical signs of pregnancy beyond 12 weeks of gestation. Once a viable pregnancy is confirmed by transvaginal ultrasound visualization, the chance of spontaneous abortion is about 5%, which means that the ongoing pregnancy rate beyond 12 weeks is a little less than the clinical pregnancy rate.

Our ongoing pregnancy rate is calculated per oocyte (egg) retrieval. This rate means the cumulative outcome of pregnancy in a treatment cycle (if a patient has several embryos for transfer, we will count until the viable pregnancy is achieved in any transfer cycle in the stimulation). Usually cumulative outcome will be higher than per one procedure, but the data can provide information on what the real success rate is per patients receiving treatment; that is to say, what percentage of patients who come to us for treatment go on to have a baby or go on to give birth.

Ongoing pregnancy (more than 12 weeks) is an important time point in gestation. Modern publications in international journals use ongoing pregnancy rates as a measure of success of an IVF cycle. Statistically, out of 100 positive pregnancy tests (biochemical pregnancies), 83–85% reach ongoing pregnancy. The remaining pregnancies (15–17%) will result in a miscarriage or result in only a biochemical pregnancy (rise and fall of hCG).

Live birth rate

Live birth rate means the rate of pregnancies resulting in live births. Our live birth rate per oocyte retrieval is the cumulative outcome of several transferred cycles resulting in live births in a cycle of oocyte retrieval. The percentage of transfers resulting in live births is the best way to evaluate a fertility clinic’s IVF success rate and the performance of the clinic.

The transfer of multiple embryos increases pregnancy success, but also increases the risk of multiple births. In clinics where doctors transfer more than two embryos, the implantation rate will be higher but the ongoing clinical pregnancy rate will be lower due to the spontaneous miscarriage rate being eliminated. would be high but the ongoing clinical pregnancy rate would be lower from eliminating spontaneous miscarriage rate.  However, the live birth rate might not be good because there will be some pregnancies that result in preterm and stillbirths from multifetal pregnancies.

Our success rate benchmarked with SART(Society of Assisted reproductive technologies, US)

We have benchmarked our pregnancy outcome against SART (Society of Assisted Reproductive Technologies, US) national data in 2014. Our cumulative live birth rate per egg retrieval in patient’s aged less than 37 years old is above the national US data.

Our success rate on donor cycle

Our clinical pregnancy rate per patient in patients who use donor eggs is rising every year, which is the result of good quality control in our IVF laboratory, good skills and techniques and the improvement of fertility drugs and culture media.
