Knowledge and Attitude of Infertile People toward Assisted Reproductive Techniques in Hamadan, Iran.

Background: People's knowledge and attitude play a role in deciding whether or not to use assisted reproductive procedures (ART). There is no information about people's attitudes and awareness about ART in western Iran. Thus, this study was performed to determine the knowledge and attitude of infertile people toward ART. Methods: This cross-sectional study was performed on 124 infertile participants who referred to the in vitro fertilization section of Fatemieh hospital, Hamadan, Iran. To measure the knowledge and attitude of the participants, 2 researcher-made questionnaires were used. Their validity and reliability were confirmed by content validity (eg, content validity index [CVI]; content validity ratio [CVR] ) and the Cronbach alpha, respectively. Results: The study involved 124 participants, more than half of whom were women (54.8%). The mean of the CVI and the CVR for the attitude questionnaire was 0.76 and 0.79, respectively, and for the knowledge, questionnaire was 0.72 and 0.71, respectively. The Cronbach alpha coefficient obtained for the attitude and knowledge questionnaires was 0.761 and 0.745, respectively. The mean (SD) of the attitude and knowledge of infertile people toward the use of ART was 15.33 ± 2.91 and 9.04 ± 2.92, respectively. The study reported that participants' age, inhabitation, and job status had a significant effect on their attitude score. Also, the study found that the knowledge score was inversely related to age. The knowledge in those who were unemployed and living in the rural and less than those employed and living in urban areas, respectively. Conclusion: The 2 questionnaires designed in this study (knowledge and attitude) have the required validity and reliability. As a result, it appears that increasing people's knowledge and improving their attitude, particularly among the elderly, is necessary.

ADAMTS proteoglycanases downregulation with impaired oocyte quality in PCOS

ABSTRACT Objective: A disintegrin and metalloproteinase with thrombospondin motifs 4 (ADAMTS-4) and ADAMTS-5 normal expression levels are essential for ovulation and subsequent fertilization. The objective of the present study was to assess expression pattern of these genes in cumulus cells (CCs) taken from patients with polycystic ovary syndrome (PCOS) and to investigate any possible relationship with the oocyte quality. Subjects and methods: ADAMTS-4 and -5 expression levels within CCs containing oocytes at the metaphase II (MII) and germinal vesicle (GV) stages, taken from 35 patients with PCOS and 35 women with normal ovarian function, were investigated using RT-qPCR. Moreover, possible correlations between ADAMTS-4, ADAMTS-5, and progesterone receptors (PRs) expression as well as oocyte quality were evaluated. Results: ADAMTS-4 and -5 expression levels were dramatically diminished in the CCs of the PCOS patients when compared to the controls. ADAMTS-4 and -5 expression levels were correlated with each other and with the oocyte quality. Furthermore, lower expression levels of ADAMTS-4 and -5 in the PCOS patients were strongly correlated with the diminished PRs expression levels. Conclusions: Downregulation of ADAMTS-4 and -5 in the human CCs of the PCOS patients correlated with the decline in the PRs expression, and impaired oocyte quality may cause lower oocyte recovery, maturation, and fertilization rate.

Abnormal expressions of ADAMTS-1, ADAMTS-9 and progesterone receptors are associated with lower oocyte maturation in women with polycystic ovary syndrome.

PURPOSE: ADAMTS-1 and 9 play a crucial role in the ovulation and their altered levels may play a role in the pathogenesis of polycystic ovary syndrome (PCOS). The aim of this study was to assess ADAMTS-1 and 9 expression and their correlation with the oocyte quality and maturity in the cumulus cells (CCs) of PCOS patients and normovulatory women during an IVF procedure. METHODS: Expression of ADAMTS-1 and 9 and progesterone receptors (PRs) in the CCs containing MII and germinal vesicle (GV) oocytes of 37 PCOS patients and 37 women with normal ovulatory function who underwent IVF treatment was evaluated using qRT-PCR. Moreover, correlation between ADAMTS-1 and 9 expression and oocyte quality were also investigated. RESULTS: mRNA expression levels of ADAMTS-1 and ADAMTS-9 were significantly reduced in the women with PCOS compared to the normovulatory women. ADAMTS-1 and ADAMTS-9 mRNA expression levels in the CCs showed a considerable correlation. Lower expression levels of ADAMTS-1 and ADAMTS-9 in PCOS patients were strongly correlated with diminished oocyte maturation. There was a remarkable association between ADAMTS-1 and ADAMTS-9 mRNA expression levels and oocyte quality. PRs (PRA and PRB) were dramatically decreased in PCOS patients when compared with the control group. CONCLUSIONS: The results of the present study indicated that ADAMTS-1 and ADAMTS-9 as well as PRs are downregulated in the human CCs in PCOS patients, which could be associated with impaired oocyte maturation and may result in a lower oocyte recovery and oocyte maturity rates, as well as lower fertilization rate.

Estrogen and progesterone receptor subtype expression in granulosa cells from women with polycystic ovary syndrome.

We evaluated gene expression of estrogen and progesterone nuclear receptors in granulosa cells (GCs) of polycystic ovary syndrome (PCOS) women compared to women with normal cycling ovaries (control group) to achieve a better understanding of ovarian steroid status in patients with PCOS. In this prospective study, 40 patients with PCOS and 40 women with normal ovulatory function who underwent in vitro fertilization (IVF) for treatment of tubal and/or male infertility were recruited. Follicular fluid was collected from patients and GCs were isolated from follicular fluid and then were purified with Micro Beads conjugated to monoclonal anti-human CD45 antibodies. RNA was extracted and reverse transcription was performed. Gene expression of estrogen and progesterone receptors was determined by quantitative real time PCR (qRT-PCR). Estrogen receptor ß (ERß) expression was significantly higher than ERα expression in both groups (p < 0.002). ERα and ERß mRNA expression in PCOS was significantly lower than control group (p < 0.002). The expression levels of PRA and PRB in PCOS was significantly lower than control group (p < 0.002). In conclusion, a significant reduction of these genes in GCs from follicles of women with PCOS could be considered as a sign for maturation defect or follicular arrest in GCs.
