Comparison of the ultrashort gonadotropinreleasing hormone agonist-antagonist protocol with microdose flare-up protocol in poor responders: a preliminary study

Objective: To determine the potential effect of the ultrashort gonadotropin-releasing hormone (GnRH) agonist/GnRH antagonist protocol versus the microdose GnRH agonist protocol in poor responders undergoing intracytoplasmic sperm injection (ICSI). Material and Methods: The patients in the Agonist-Antagonist Group (n=41) were administered the ultrashort GnRH-agonist/antagonist protocol, while the patients in the Microdose Group (n=41) were stimulated according to the microdose flare-up protocol. The mean number of mature oocytes retrieved was the primary outcome measure. Fertilization rate, implantation rate per embryo and clinical pregnancy rates were secondary outcome measures. Results: There was no differenc between the mean number of mature oocytes retrieved in the two groups. There were also no statistical differences between the two groups in terms of peak serum E-2 level, canceled cycles, endometrial thickness on hCG day, number of 2 pronucleus and number of embryos transferred. However, the total gonadotropin consumption and duration of stimulation were significantly higher with the Agonist-Antagonist Group compared with the Microdose Group. The implantation and clinical pregnancy rates were similar between the two groups. Conclusion: Despite the high dose of gonadotropin consumption and longer duration of stimulation with the ultrashort GnRt-t agonist/antagonist protocol, it seems that the Agonist-Antagonist Protocol is not inferior to the microdose protocol in poor responders undergoing ICSI.Amaç: ICSI uygulanan zayıf over cevaplı hastalarda ultra kısa GnRH agonist/GnRH antagonist protokolünün mikrodoz GnRH agonist protokolüne karşı potansiyel etkisini belirlemek. Gereç ve Yöntemler: Mikrodoz grubundaki (n=41) hastalar mikrodoz flare up protokolüne uygun olarak stimüle edilirken AgonistAntagonist grubundaki (n=41) hastalara da ultra kısa GnRH-agonist/ antagonist protokolü uygulandı. Bu çalışmanın primer sonuç değeri toplanan ortalama matür oosit sayısı iken, fertilizasyon oranı, embryo başına implantasyon oranı ve klinik gebelik oranı da sekonder sonuç değerleriydi. Bulgular: İki grup arasındaki toplanan ortalama matür oosit sayıları arasında fark yoktu. Serum E2 düzeyleri, iptal edilen sikluslar, hCG günü endometrial kalınlığı, 2 pronukleus sayıları ve transfer edilen embryo sayılarında da iki grup arasında istatistiksel farklılıklar yoktu. Bununla birlikte Agonist-Antagonist grubunda total gonadotropin tüketimi ve stimülasyon süresi Mikrodoz grubuyla karşılaştırıldığında belirgin olarak daha yüksekti. İki grup arasındaki implantasyon ve klinik gebelik oranları ise birbirine benzerdi. Sonuç: Ultra kısa GnRH agonist/ antagonist protokolü ile yüksek doz gonadotropin tüketimi ve daha uzun süreli stimülasyona rağmen ICSI uygulanan zayıf over cevaplı hastalarda Agonist-Antagonist Protokolünün mikrodoz protokolünden daha az etkili olmadığı görülmektedir.

Transuterine Migration and Bowel Injury as a Complication of Intrauterine Contraceptive Device

Intrauterine contraceptive dev ice (IUD) is a widely accepted method of contraception. Although IUD is one of the most effectiv e contraceptiv e methods, the migration of it f rom the uterus is a rare but an extremely serious complication. The aim of this report is to emphasize the management and therapy of this complication

Can hyaluronan binding assay predict the outcome of intrauterine insemination in couples with unexplained or mild male factor infertility?

The purpose of this study was to evaluate the prognostic effect of Hyaluronan Binding Assay (HBA) which has been used as a method of sperm selection for intracytoplasmic sperm injection procedure, on the outcome of intrauterine insemination (IUI) in couples with unexplained or mild male factor infertility

Electrocardiographic P-Wave Duration, QT Interval, T Peak to End Interval and Tp-e/QT Ratio in Pregnancy with Respect to Trimesters

Background: P-wave duration helps to determine the risk of atrial arrhythmia, especially atrial fibrillation. QT interval, T peak to end interval (Tp-e), and Tp-e/QT ratio are electrocardiographic indices related to ventricular repolarization which are used to determine the risk of ventricular arrhythmias. We search for any alterations in electrocardiographic indices of arrhythmia in the pregnancy period with respect to trimesters. Methods: We enrolled 154 pregnant and 62 nonpregnant, healthy women into this cross-sectional study. Maximum and minimum P-wave durations (Pmax, Pmin), and QT intervals (QTmax, QTmin) were measured from 12 leads. QT measurements were corrected using Fridericia (QTc-Fr) and Bazett's (QTc-Bz) correction. Tp-e interval was obtained from the difference between QT interval, and QT peak interval (QTp) measured from the beginning of the QRS until the peak of the T wave. Tp-e/QT ratio was calculated using these measurements. Results: Pmax were 93.0 +/- 9.1, 93.9 +/- 8.9, 97.9 +/- 5.6, 99.0 +/- 6.1 in nonpregnant women, first, second, third trimesters of pregnancy, respectively (P = 0.001); whereas Pmin values were not significantly different. QTc-Fr max were 407.4 +/- 14.2, 408.5 +/- 16.1, 410.1 +/- 13.1, 415.1 +/- 10.1 (P = 0.007); Tp-e were 72.7 +/- 6.2, 73.2 +/- 6.5, 77.2 +/- 8.9, 87.2 +/- 9.6 (P < 0.001); and Tp-e/QT were 0.17 (0.14-0.20), 0.17 (0.14-0.20), 0.18 (0.15-0.23), 0.20 (0.16-0.25) in nonpregnant women, first, second, and third trimesters of pregnancy respectively (P < 0.001). None of the participants experienced any arrhythmic event. Conclusions: P-wave duration is prolonged in the second trimester, and resumes a plateau thereafter. Maximum QTc interval, Tp-e interval and Tp-e/QT ratio are increased in the late pregnancy. Although these indices are altered during the course of pregnancy, they all remain in the normal ranges

The Effect of Coasting on Intracytoplasmic Sperm Injection Outcome in Antagonist and Agonist Cycle.

Coasting can reduce the ovarian hyperstimulation syndrome (OHSS) risk in ovulation induction cycles before intracytoplasmic sperm injection (ICSI). This study aimed to investigate the effect of gonadotropin-releasing hormone (GnRH) agonist and GnRH antagonist protocols to controlled ovarian hyperstimulation (COH) cycles with coasting on the parameters of ICSI cycles and the outcome
