Purpose: To compare the presence in levels of antiovarian antibodies (AOAb) in the pre- and postovulatory stage from serum of infertile patients undergoing intrauterine insemination (IUI) or in vitro fertilization (IVF) with outcome of the procedures.
Results: Serum from 36 women undergoing IUI, 36 women undergoing IVF and 25 fertile, healthy controls were assayed for the presence of AOAb by a commercially available ELISA kit. AOAb was positive in 59.7% of infertile women, while none of the fertile controls were positive for AOAb. The levels of these antibodies increased as the patient age and the number of treatment attempts increased. Though the presence of AOAb did not affect oocyte recovery rate, it resulted in decreased fertilization rate, cleavage rate, and pregnancy rate in infertile women.
Conclusions: Our studies suggest that AOAb may be a cause of infertility and presence of these antibodies could have adverse effects on the outcome of assisted reproductive techniques.

Objective: There is still much to be discovered regarding the etiopathogenesis and management of polycystic ovarian syndrome (PCOS).
Materials And Methods: Four groups of female Wister-Albino rats were established, each with a normal estrous cycle: control, D ( + ) galactose (D-galactose), (), and prepared secondary antibody (Ab2). Serum samples were collected, and histopathological examination was performed on ovaries and spleen tissues.

The objective of the study was to evaluate the profile and diagnostic significance of serum autoantibodies in infertile patients with premature ovarian insufficiency (POI). The pilot study included 26 patients of reproductive age with POI and diminished ovarian reserve who received complex treatment using new surgical technologies (Group 1) and 18 patients without POI (Group 2). The profile of serum autoantibodies, including anti-ovarian antibodies, antibodies against thyroid peroxidase (TPO), steroidogenic enzymes, and steroid and gonadotropic hormones, was studied using modified ELISAs and human recombinant steroidogenic enzymes (CYP11A1, CYP19A1, CYP21A2).

Recurrent implantation failure (RIF) is a condition where a woman fails to obtain pregnancy after multiple embryo transfer cycles, even with superior-quality blastocysts. There are various factors that can contribute to RIF, including immunologic disturbances. The immune system is extremely important during pregnancy.

Anti-ovarian antibody (AOA) could be considered an independent marker for autoimmune ovarian disease and predicting future premature ovarian failure (POF). This study aims to investigate if AOA is associated with poor ovarian response (POR) and pro-inflammatory immune responses in women undergoing assisted reproductive technology (ART) cycles. Two hundred forty-eight women undergoing ART cycles were divided into four groups based on AOA test results and the presence of POR: POR(-)/AOA(-) group (N = 148), POR(+)/AOA(-) group (N = 34), POR (-)/AOA(+) group (N = 44), POR(+)/AOA(+) group (N = 22).
