Brief Summary

Thanks to recent advances in clinical practice and laboratory, embryo cryopreservation has become the first-line procedure in assisted reproductive technology. Improved laboratory techniques have increased the number of available embryos derived from an in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycle. Implementation of a single embryo transfer policy to improve vitrification, improve postwarm embryo survival rates, and reduce multiple pregnancies without reducing cumulative birth rates has contributed to an increase in the number of frozen-warms (1,2) Embryo freezing; It is becoming an adopted practice for an increasing number of indications, including prevention of ovarian hyperstimulation syndrome, preimplantation genetic testing (PGT), late follicular phase progesterone elevation, and embryo-endometrial asynchrony. In our study, we are investigating the effect of pre-transfer serum progesterone levels on pregnancy outcomes in patients who underwent frozen-thawed embryo transfer.Supplementary progesterone preparations can be used to prevent luteal phase defect and to provide progesterone support in cycle preparations for frozen-thawed embryo transfer(3). The aim in this study is to show the effect of serum progesterone level on the pregnancy results on the day of embryo transfer in natural cycles.

Outcome Measures

Primary Outcomes (1)

  • Clinical pregnancy rates

    fetal heartbeat by transvaginal ultrasound

    average of 1 year

Secondary Outcomes (2)

  • Ongoing pregnancy rate

    average of 15 month

  • Miscarriage

    average of 15 month

Study Arms (2)

Normal Progesterone group

EXPERIMENTAL

Progesterone level ≥ 10 ng/mL on ET day.

Other: Normal Progesterone group

Low Progesterone group

ACTIVE COMPARATOR

Progesterone level \<10 ng/mL on ET day. Grup a Rescue vaginal progesterone, Grup b Rescue subcutan progesterone

Other: Low Progesterone group

Interventions

No progesterone supplementation

Normal Progesterone group

Progesterone level \<10 ng/mL on ET day. If serum progesterone levels were \<10 ng/ml at ET day, vaginal pills (Lutinus 2\*1) or SC progesterone daily (Prolutex) was given to patients and ET was performed on the same day. Progesterone supplementation was discontinued if there was no pregnancy. Progesterone supplementation at the same dose was continued until 10 gestational weeks for viable pregnancies.

Low Progesterone group
