Background: Recurrent miscarriage is considered as one of the main problems in women's reproductive health. The aim of the present study was to evaluate the natural killer cells (NK cells) and cytokines in unexplained recurrent miscarriage and fertile women.
Methods: In this case-control study, 40 women with unexplained recurrent miscarriage were assigned to the case group and 40 fertile women were assigned to the control group. NK cell subsets (CD56 CD16/CD56 CD16) and cytokines (IL-2/IL-12) levels in the peripheral blood (PB) were used for assessing immunologic problems. The percentage of peripheral blood NK cells (CD56) was identified by flow cytometry.
Results: The obtained results showed a significant difference in CD56 CD16 and CD56 CD16 between the two groups. Also, there was no significant difference in the IL-2 and IL-12 between the two groups. A cut-off value of ≥5.25% (p < 0.001) and ≥3.4% (p < 0.015) for the increased percentage of CD56 CD16 and CD56 CD16cells in the PB become predictive of recurrent miscarriage.
Conclusion: Increased NK cells in the PB of women with recurrent miscarriage strongly establish prospective researches to recognize the predictive value of these parameters in the evaluation of patients with recurrent miscarriage.

Objective: Abnormal levels and imbalances of T cell subsets are common in recurrent spontaneous abortion (RSA) patients, but most studies have small sample sizes, and comprehensive evaluations are lacking. Therefore, this meta-analysis aimed to comprehensively investigate T cell subsets and their ratios in RSA patients.
Methods: Four databases (PubMed, EMBASE, Web of Science, and Cochrane Library databases) were searched until 10 January 2024.

Background: Recurrent pregnancy loss (RPL) remains a complex and challenging reproductive issue often associated with immunological abnormalities. This study investigates the immunomodulatory effects of intradermal lymphocyte therapy in RPL patients, exploring cellular, molecular, and cytokine changes, with specific attention to individuals with positive anti-thyroid peroxidase antibodies (Anti-TPO).
Methods: The study included 105 patients with RPL, divided into Anti-TPO positive RPL patients (n = 25), Anti-TPO negative RPL patients (n = 38), and RPL patients without lymphocyte immunotherapy (LIT) (n = 42).

Recurrent miscarriage (RM) is a reproductive disorder affecting couples worldwide. The underlying molecular mechanisms remain elusive, even though emerging evidence has implicated endoplasmic reticulum stress (ERS). We investigated RM- and ERS-related genes to develop a diagnostic model that can enhance predictive ability.

Background: This study aimed to analyze the impact of preoperative cervical length before cervical cerclage on the extension of gestational days in patients with various diagnostic types of cervical insufficiency, including obstetric history-based diagnosis, ultrasound-based diagnosis, and physical examination-based diagnosis.
Methods: 168 patients were segregated into four categories based on cervical length: 0-0.4 cm, 0.
