Purpose: Multiple factors have been shown to influence the rate of clinical pregnancy after FET in IVF treatment, including embryo quality, synchronization of embryo and endometrium, and endometrial receptivity (ER). The subendometrial blood flow conditions could also contribute potentially major effects toward the establishment and maintenance of pregnancy. We conducted a retrospective cohort study to examine the correlation between subendometrial blood flow, as determined by Doppler ultrasound, and pregnancy outcomes in IVF patients with a thin endometrium (endometrium thickness [EMT] ≤ 0.

- - The study aims to compare pregnancy outcomes between preimplantation genetic testing for aneuploidy (PGT-A) and standard in vitro fertilization and embryo transfer (IVF-ET), focusing on how outcomes vary with different oocyte and blastocyst counts.
- - A total of 1,212 infertile women participated, and the main outcomes measured included cumulative live birth rates (LBR), clinical pregnancy loss rates, and successful birth outcomes.
- - Results indicated that PGT-A may lead to lower cumulative clinical pregnancy loss compared to IVF-ET when fewer than 15 oocytes are retrieved, but it showed a lower cumulative LBR when 19-23 oocytes were retrieved.

Research Question: Do infertile women with positive tuberculin skin test (TST) results have a higher risk of adverse pregnancy outcomes after IVF or intracytoplasmic sperm injection and embryo transfer (ICSI-ET) and does preventive anti-tuberculosis treatment applied to infertile women with positive TST results before IVF/ICSI-ET affect pregnancy and neonatal outcomes?
Design: This was a retrospective cohort analysis of 6283 infertile women who underwent IVF/ICSI-ET treatment for the first time at the Reproductive Hospital affiliated to Shandong University from November 2016 to September 2022. None of the participants had prior tuberculosis or active tuberculosis. According to their TST results, 5947 patients who had never received preventive anti-tuberculosis treatment were divided into a TST-positive group (1704 cases) and a TST-negative group (4243 cases).
