Ovarian follicular concentration of IL-12, IL-15, IL-18 and p40 subunit of IL-12 and IL-23.

Background: The aim of the study was to determine the presence of interleukin (IL)-12, IL-15, IL-18 and p40 subunit of IL-12/IL-23 in follicular fluid from spontaneous cycles and the relation between the concentration of selected cytokines and IVF-embryo transfer outcome.

Methods: IVF-embryo transfer and enzyme immunoassay (EIA) (R&D Systems, Minneapolis, MN, USA and MBL, Nagoya, Japan) were used.

Results: Follicular fluid of women included in the IVF-embryo transfer procedure contained common p40 subunit of IL-12/IL-23 (median 70.

Antisperm antibodies in semen, sera and follicular fluids of infertile patients: relation to reproductive outcome after in vitro fertilization.

Problem: Data given in the literature, regarding the influence of antisperm antibodies (ASA) in the semen and/or sera on in vitro fertilization (IVF) procedure outcome are controversial. The aim of this study was to compare the prevalence of ASA in semen, peripheral blood and follicular fluid as well as to determine total immunoglobulin concentration in the serum and follicular fluid. Selected parameters were analyzed with regard to IVF outcome.

Influence of hormonal stimulation on in vitro fertilization/embryo transfer outcome.

Objective: To compare efficacy and efficiency of ovarian stimulation therapy.

Study Design: Retrospective study compares ovarian response as number of retrieved oocytes, fertilization rates, endometrial patterns, number of pregnancies and pregnancy rates to different stimulation protocols.

Results: The least number of cancelled cycles was in long protocols with buserelin.
