Objectives

Narrative objectives1

We examine whether an administration of Hishi extract decreases advanced glycation end-products (AGE) in the endometrium, improving pregnancy rate in cryopreserved and thawed blastocyst transfers in natural cycles.

Interventions/Control_1

Infertile women who meet inclusion criteria and do not meet exclusion criteria are prospectively allocated into two groups of A (Hishi group) and B (control group) at random. Women can freely decide to participate in the trial. Informed consents are obtained from all participants after they have received appropriate explanations about implications, purposes, methods, expected benefits, and possible risks, and the protection of privacy.
In the A group, serum and endometrial tissue are obtained on day 5-7 of luteal phase in the first natural cycle and administration of Hishi extract, 100 mg/day is started from the day 1 of the next 2nd natural cycle. Serum and endometrial tissue are obtained again on day 5-7 of luteal phase in this 2nd natural cycle. In the following 3rd natural cycle, cryopreserved and thawed blastocyst transfer (CT-BT) is carried out under administration of Hishi extract. If pregnancy is not obtained, administration of Hishi extract is discontinued immediately and if women wish, CT-BT is carried out without Hishi extract in the 4th natural cycle.
In natural cycles with CT-BT, ovulations may be triggered by GnRH agonist-induced LH-surge or hCG administration and luteal phase may be supported by administration of progesterone or hCG. But ovarian stimulations, hormone replacement therapy, and treatments specifically stimulating implantations must not used.
Serum and endometrial tissue are cryopreserved and analyzed later on AGE and CD138 expression.

In April, 2024, we decided to stop further retrieval of blood and endometrial tissue and to continue hereafter only CT-BT because of difficulty of subject recruitment. We had collected blood and tissue in 21 cases for 3 years until this April, 2024. Also, interim analysis detected most prominent effects in birth rate and so we changed to make birth rate per embryo transfer as primary outcome and added birth rate per hCG positive case into secondary outcomes.

Interventions/Control_2

In the B (control) group, serum and endometrial tissue are obtained on day 5-7 of luteal phase in the first natural cycle and CT-BT is carried out in the next 2nd natural cycle. When pregnancy is not achieved, administration of Hishi extract, 100 mg/day is started immediately if women wish. Serum and endometrial tissue are obtained again on day 5-7 of luteal phase in this 3rd natural cycle. In the following 4th natural cycle, CT-BT is carried out under administration of Hishi extract. If pregnancy is not obtained, administration of Hishi extract is discontinued immediately.

In April, 2024, we decided to stop further retrieval of blood and endometrial tissue and to continue hereafter only CT-BT because of difficulty of subject recruitment. We had collected blood and tissue in 20 cases for 3 years until this April, 2024. Also, interim analysis detected most prominent effects in birth rate and so we changed to make birth rate per embryo transfer as primary outcome and added birth rate per hCG positive case into secondary outcomes.

Key inclusion criteria

The study includes infertile women who satisfy all the following criteria; (1) she is planning to have cryopreserved-thawed blastocyst transfer (CT-BT) in natural cycles, (2) she has failed to deliver with 1-3 attempts of embryo transfer containing at least one superior blastocyst or cleaving embryo, (3) embryos used in the planning CT-BT must include at least one superior blastocyst when they were cryopreserved, which were produced by ovarian stimulation using long protocol, antagonist protocol, clomiphene citrate-hMG protocol, or PPOS, and (4) 42 years old or younger on the date of oocyte retrieval when she cryopreserved blastocysts which is used in the planning CT-BT.

Key exclusion criteria

Women are excluded when they meet any of the following criteria; (1) organic uterine infertility (Asherman syndrome, uterine anomaly, and submucosal myoma larger than 1.5 cm in diameter), (2) severe diminished ovarian reserve (AMH<0.01 ng/mL, day-3 FSH > 15 IU/L, day-3 E2 > 70pg/mL, or no ovary observed under ultrasound), (3) diabetes or taking anti-diabetic medicine, and (4) having her partner with azoospermia.
