Comparison of follitropin alfa and urinary gonadotropins in IVF cycles.

AIM: The aim of this study was to compare human menopausal gonadotropins with recombinant follicle stimulating hormone-follitropin alpha following a long down-regulation protocol in intra cytoplasmic sperm injection cycles in our clinic, and to review the outcomes in the light of preceding studies. METHODS: This was a retrospective study. Among a total number of 2798 patients who had undergone IVF/ICSI applications, 579 eligible patients were included, and their data were evaluated retrospectively. Three hundred eighteen patients were treated with follitropin alpha and 255 patients were treated with hMG. Total units of follitropin alpha preparations used in ovulation induction, total number of meiois-2 phase oocytes, total number of used oocytes in ICSI cycle, fertilization rate and clinical pregnancy rates of both groups were analyzed. RESULTS: Mean duration of stimulation was longer in the group of patients treated with rFSH-α compared to the second group of patients treated with hMG (8.88 days and 8.55 days, respectively; P<0.05). The number of transferred embryos were 3.08 and 2.68 for patients treated with follitropin alpha and hMG, respectively (P<0.05). Clinical pregnancy rates were %28 and %33 in the groups of patients treated with follitropin alpha and hMG, respectively. Even though a greater clinical pregnancy rate was noted in the hMG group, there was no statistically significant difference between the two groups (P>0.05). CONCLUSION: Our results indicate that there is no statistically significant difference between follitropin alpha and human menopausal gonadotropin in terms of the clinical pregnancy rates.

Reduction of dehydroepiandrosterone sulfate synthesis in women with polycystic ovary syndrome by human menopausal gonadotropin but not purified urinary follicle stimulating hormone: a comparative pilot study.

We aimed to compare the effects of two different gonadotropins on steroid production in patients with polycystic ovary syndrome (PCOS). The study group comprised 20 infertile patients diagnosed with PCOS who were accepted into in vitro fertilization-embryo transfer and gamete intra-Fallopian transfer programs. Ten patients were consecutively allocated to a purified urinary follicle stimulating hormone (FSH) administration group while the other ten received human menopausal gonadotropin (hMG). All patients were pretreated with a gonadotropin releasing hormone-agonist. The patients were followed by daily vaginal ultrasonography until at least two follicles reached a diameter of 17 mm or an estradiol value of at least 100 pg/ml per follicle. To induce ovulation, human chorionic gonadotropin was given. On the 3rd day of menstruation, serum estradiol, luteinizing hormone (LH), FSH, total testosterone, androstenedione, dehydroepiandrosterone sulfate (DHEAS), insulin-like growth factor-I and insulin were measured. These same parameters were measured again on the day of follicle aspiration in both serum and follicular fluid. In both groups, the serum levels of estradiol and androstenedione were raised significantly, and on aspiration day the serum level of DHEAS was significantly raised in the FSH group but not in the hMG group. Our findings suggest that in PCOS patients exogenous hMG induces a different steroid synthesis pattern compared to pure FSH, hypothetically by reduction of the delta-5 steroid synthesis pathway in the adrenals and/or in the ovary.

Hydrosonography in screening for intracavitary pathology in infertile women.

OBJECTIVES: We evaluated the value of hydrosonography in screening for intracavitary pathologies in infertile patients. METHODS: A total of 93 infertile women with suspected intracavitary lesions on transvaginal ultrasonography (TVS) underwent hydrosonography. Specimens obtained either by dilatation and curettage or hysteroscopic resection were compared with findings on TVS and hydrosonography. RESULTS: Pathology confirmed the presence of sonographically diagnosed intracavitary lesions in 40 out of 66 (60%) women. The sensitivity, specificity, positive predictive value, and negative predictive value of TVS for the detection of endometrial cavity lesions were 78%, 38%, 61%, and 59%, respectively. Forty-six out of 71 (65%) women who were found to have intracavitary lesions on hydrosonography were pathologically confirmed. The sensitivity, specificity, positive and negative predictive value of hydrosonography in the detection of endometrial cavity lesions were 90%, 40%, 65%, and 77%, respectively. CONCLUSIONS: Hydrosonography is a useful procedure in screening for intracavitary pathologies and allows differentiation of intracavitary, endometrial, and submucosal abnormalities.

Significance of yolk sac measurements with vaginal sonography in the first trimester in the prediction of pregnancy outcome.

BACKGROUND: The purpose of this prospective clinical study was to determine and evaluate the prognostic value of secondary yolk sac diameter of the embryo on pregnancy outcome. METHODS: One hundred and thirty pregnant women in the first trimester were included in the study. Crown-rump length (CRL) and yolk sac diameters were measured in every patient and the outcome of the pregnancies were compared with the measurements. Intact normal pregnancy (group A), threatened abortion (group B) and missed abortion (group C) were diagnosed in 67, 43 and 20 pregnancies, respectively. RESULTS: We detected a significant linear correlation between secondary yolk sac diameter and gestational age in group A (r = 0.5085; p < 0.0001) and a moderate correlation in group B (r = 0.4048; p = 0.007) and C patients (r = 0.3478; p = 0.1333). When the groups were evaluated irrespective of gestational age, a significant difference in secondary yolk sac diameters among the groups was noted (p = 0.037). When confidence intervals for secondary yolk sac diameters of intact normal pregnancies (group A) were calculated by linear regression, two patients in group B were below the 5% confidence interval. However, in group C patients, the yolk sac diameter of six patients were detected below the 5% confidence interval, while two of the measurements were above 95% confidence interval. Therefore, eight measurements (40%) of group C patients were outside the 5-95% confidence interval. CONCLUSION: In the first trimester, when discrepancy is detected between secondary yolk sac diameter and gestational age, additional sonographic investigation should be performed one or two weeks later, in order to estimate the pregnancy outcome.
