OBJECTIVE: The aim was to evaluate whether the differences of PG concentration in follicular and peritoneal fluid during preovulatory phase exist between the women with and without endometriosis. MATERIAL AND METHODS: Twenty-three patients with endometriosis, 8 were stage I-II and 15 were stage III-IV, and another 23 patients without endometriosis were undergone laparotomy during late follicular phase. Peritoneal fluid from 46 patients and follicular fluid from 42 patients were obtained, and these samples were analyzed double times for PGF2alpha, PGE2 and estradiol. RESULTS: The mean level of PGF2alphain the peritoneal fluid was significantly higher in the group with endometriosis than in the control(P=0.0293), especially more significant in stage I-II endometriosis. Although there was no significant difference of PGF2alphaconcentration in the follicular fluid between the groups, the stage III-IV endometriosis group showed slightly higher PGF2alphalevel than both the stage I-II group and the control(P=0.0604). And also, there was significant positive correlation with the level of PGF2alphaand estradiol in the follicular fluid only in the endometriosis group(r=0.4988, P=0.0154), not in the control. However, there was no difference in the level of PGE2 and estradiol in the peritoneal or follicular fluid between the groups. CONCLUSION: Some alterations of PGF2alphalevel exist in the women with endometriosis. These are significantly higher PGF2alphalevel in peritoneal fluid with mild endometriosis and slightly higher PGF2alphalevels in follicular fluid with extensive endometriosis during preovulatory phase, which suggest that PGF2alphamay play some roles in subfertility associated with endometriosis.

Extracellular vesicles (EVs) are membrane-bound particles actively released by cells. In prokaryotes and eukaryotes, EVs are effective bridges for communication between cells. EVs carry biological macromolecules, including proteins, lipids and nucleic acid, which affects different physiological functions of parent cells and recipient cells. Among them, the microRNA carried by EVs is the most reported and plays an important role in physiological function of organisms. During the development of follicles, only a few follicles can fully develop and ovulate, whereas most of them undergo atresia at different stages of development. In the whole process of follicular development, the changes at each stage and the regulation mechanism of follicular atresia are not completely understood. In this paper, we introduced the types, characteristics, isolation methods and uses of EVs, and emphasized how microRNA carried by EVs in follicular fluid regulated follicular atresia from the aspects of different cytokines and hormones. Additionally, the application prospect of microRNA carried by EVs in follicular fluid in reproductive regulation and reproductive disease diagnosis was discussed. This paper is significant for studying the regulation of follicular development and the effective utilization of oocytes.

OBJECTIVE: We tested the usefulness of swim-down technique using human follicular fluid (hFF) in sperm preparation. METHODS: Semen samples were obtained from twelve male partners showing asthenozoospermia (sperm motility < 50%) at the time of routine andrologic evaluation in Seoul National University Bundang Hospital. After dividing into two aliquots, each samples were processed either by swim-down using 100% hFF or density gradient using SpermGrad. Sperm quality was assessed by computer-assisted semen analyzer (CASA). RESULTS: Motility, Rapid motility, VCL (curvilinear velocity), ALH (amplitude of lateral head displacement), and hyperactivated sperms were significantly increased, and LIN (mean linearity) was decreased significantly after sperm preparation in both groups. Motility was significantly higher after swim-down using 100% hFF when compared with density gradient using SpermGrad (81.2+/-4.7 vs. 67.6+/-2.3, p=0.02). The other parameters assessed by CASA were not different between the two methods. CONCLUSION: Swim-down method with 100% hFF may be a useful method in preparation of sperm from asthenozoospermia.

OBJECTIVE: The purpose of the present study was to determine whether a relationship exists between the clinical symptoms (dysmenorrhea and infertility) and prostaglandin (PG) concentrations in follicular and peritoneal fluid in the women with endometriosis during the late follicular phase of the menstrual cycle. METHODS: Thirty patients with pelvic endometriosis diagnosed by pelvic surgery were enrolled. Eight patients were suffering from severe dysmenorrhea and 11 had history of primary or secondary infertility among them. Endometriosis patients were grouped by the presence of each symptom and compared with 33 control patients without endometriosis. Peritoneal fluid was collected in the beginning of peritoneal opening and dominant follicular fluid was aspirated by syringe needle at the time of operation. Then PGE2 and PGF2a concentration were measured at each tube. RESULTS: Follicular fluid PGF2a levels were increased in 30 endometriosis patients (P=0.003), and the levels were significantly higher in 11 patients with infertility compared with the control (P=0.001). Peritoneal fluid PGF2a levels were significantly higher in 8 patients with severe dysmenorrhea compared with the others or the control (P=0.028). Follicular or peritoneal fluid PGE2 levels were not different between any group and the control. There was no significant correlation between size of endometrioma and each PG levels. CONCLUSION: Severe dysmenorrhea in endometriosis patients would be related with the high level of peritoneal fluid PGF2a concentration, and infertility in endometriosis would be related with the high level of follicular fluid PGF2a concentration.

OBJECTIVE: The purpose of this study was to evaluate the effect of polycystic ovarian follicular fluid on sperm motility in human in vitro fertilization (IVF). METHODS: From May, 1998 to July, 1999, 55 patients who complained of infertility were involved in this study. We obtained ovarian follicular fluids form the patients by ultrasono-guided aspiration. Subjects were divided into two groups. 20 patients who had polycystic ovarian disease were belong to study group, and 25 patients who had normal ovarian follicular fluid were belong to control group. The follicular fluid dilution was done with Ham's fluid as 10%, 20%, 50%, 100%. The sperm motility was analyzed by CASA at 6hr and 12hr after incubation in follicular fluids. RESULTS: The levels of average path velocity (VAP) in all concentration fluid didn't show significant difference between study and control group. The other parameters including curvilinear velocity (VCL), amplitude of lateral head displacement (ALH), and linerity (LIN) were didn't show any significant difference between both groups. CONCLUSION: PCOD fluid had seemed to have an adverse effect on the sperm biological function. But, this study showed that PCOD fluid had no different effect on sperm motility with normal follicular fluid.
