Here are the average AMH values in ng/dL and the 95% confidence interval of AMH for patients that did IVF with oocyte retrieval in 2024 and early 2025 at our center.

From 1/1/22 through 4/15/25 our center has performed 88 single day 5 fresh embryo transfers after vitrified donor oocyte thaw and ICSI.

The study referenced below looked at 3 years of IVF data in the United States reported to SART (Society for Assisted Reproductive Technology).

It seems that use of letrozole (Femara) during modified natural embryo transferers results in lower pregnancy rates.

Based on euploid embryo transfer data at our center, the average HCG at 4 weeks 5 days gestation is 1830 mIU/mL and this increases by an average of 115% every two days.

Between 1/1/2023 and 4/7/2025 our office has performed 23 single euploid embryo transfers to gestational carriers resulting in 16 ongoing pregnancies with a fetal heartbeat (70%).

Sperm concentration and morphology appear to be the most predictive indicators of the optimal method of fertilizing oocytes.

14 days after embryo transfer, an HCG value of 500 mIU/mL or higher is a good indicator that the pregnancy will progress to the point where a fetal heart beat will be detected on transvaginal ultrasound.

Laser assisted hatching does not appear to have any impact on pregnancy rates after frozen embryo transfer.

In general, transfer of one embryo at a time is best and will result in 1.5% of pregnancies being twin pregnancies (1).
