Methods: This retrospective study included 1011 ICSI cycles of women with high baseline FSH levels (> 10 IU/L), from a tertiary university IVF center between 2010 and 2015. Logistic regression analysis was performed to evaluate the prognostic factors of clinical pregnancy and live birth. Results: Among the 1011 ICSI cycles, the clinical pregnancy and live birth rates per oocyte retrieval were 19.5% and 14.3%, respectively. The live birth rates were 21.1% and 1.7% in women aged ≤30 years and those aged ≥40 years, respectively. In addition, the live birth rate was 1.47-fold higher in women from whom >3 oocytes were retrieved, compared to those from whom ≤3 oocytes were retrieved (p=0.047). Logistic regression analysis indicated that the age categories ≤30y, 36-39y and ≥40y, level of baseline FSH (≥20 IU/L) and the ovarian response (≤3 or >3 oocytes retrieved) were significantly associated with live birth. Conclusions: Our study indicated that age, baseline FSH level, and ovarian response are independent predictive factors for clinical pregnancy and live birth among women with baseline FSH levels >10 IU/L.

Methods: A total of 1544 consecutive ICSI cycles of women aged between 18-45 years, performed in a single tertiary In-Vitro Fertilization (IVF) Center between 2015-2018, were retrospectively analyzed. Along with patients' ages and AMH levels, cycle characteristics, clinical pregnancy and live birth outcomes were evaluated. Age and serum AMH levels were categorized. Regression analyses were used to determine the predictive value of AMH on the ovarian response and clinical pregnancy/live birth outcomes. Results: Among 1544 cycles, 1306 (84.6%) were ended with an embryo transfer cyle. AMH levels were found significantly positively correlated with the numbers of obtained oocytes and 2-pronuclear(2pn) zygotes. AMH value of >1 ng/ml was significantly and independently associated with obtaining more than 5 oocytes (OR: 6.7; 95% CI: 4.9-9.1). The clinical pregnancy and live birth rates per cycle were significantly lower in patients with low AMH for both age <35 and above 35 years groups. However, live birth rates per embryo transfers were not significantly different(25.6% vs 32.8%, p=0.065 for women <35 years age and 17.8% vs 21.8%, p=0.273 for women >=35 years age). Moreover, only age and number of metaphase-2 oocytes were found significant independent predictors for live birth outcome.

Comparison was made based on the number of retrieved and fertilized oocytes, metaphase 2 (M2, mature) oocytes, and transferred embryos, as well as fertilization, pregnancy, and live birth rates. Ultrasound-guided transvaginal oocyte retrieval for in vitro fertilization is one of the most common minor surgical procedures. Despite this, it is stressful and painful for the patient; most patients request sedation and/or pain relief. Propofol, which is frequently used for general anesthesia in such procedures, has been suspected to damage oocytes. Materials and methods: Results from 70 patients without premedication were compared in this randomized prospective study. Patients were divided into 2 groups based on treatment. Th ose in Group G received intravenous general anesthesia with atropine (10 μg kg-1), remifentanil (1 μg kg-1), and propofol (2.5 mg kg-1), while patients in Group P received a paracervical block with 100 mg of prilocaine (2%) and 0.75 mg kg-1 of intramuscular meperidine. Results: Our results revealed no statistically signifi cant diff erence between the 2 groups in terms of the fertilization rate. Th e numbers of retrieved and mature oocytes and transferred embryos and the pregnancy rate were greater in the general anesthesia group, although only the number of transferred embryos showed a statistically signifi cant diff erence (P = 0.045). Conclusion: According to our data, both anesthesia techniques can be used for oocyte retrieval since there were no diff erences in fertilization, pregnancy, or live birth rates between the 2 groups.

In our prospective pilot study, we used a new dynamic tissue perfusion measurement method to evaluate this relationship in humans. A standard ovulation induction and embryo transfer method were applied to all the volunteers. On the day of embryo transfer, dynamic images of the uterus were recorded using colour Doppler ultrasound, and these images were uploaded onto PixelFlux Chameleon Software (GmbH, Münster, Germany). After determining the region of interest (ROI), the average velocity, intensity, and area values for all coloured pixels in the ROI, the tissue resistance index (RI) and the tissue pulsatility index were calculated. Endometrial thickness, morphology and dynamic endometrial perfusion parameters were compared between the clinically pregnant and non-pregnant groups. Endometrial thickness, morphology values and endometrial dynamic tissue perfusion measurements were similar between the groups. This study compared perfusion parameters between clinically pregnant and non-pregnant patients by accurately calculating endometrial tissue perfusion using standard software to establish its relationship with implantation success in IVF treatment.IMPACT STATEMENTWhat is already known about this subject? The relationship between IVF success, endometrial receptivity and perfusion is known. Clear valuations of endometrial receptivity require an endometrial biopsy which may cause endometrial damage to the actual IVF cycle. This problem has led researchers to conduct non-interventional studies. Studies have revealed the value of endometrial thickness, pattern and Doppler examination of endometrial uterine arteries in predicting the success of IVF treatment.What do the results of this study add? This prospective pilot study is the first one to use this programme in humans to evaluate uterine receptivity in IVF. Successful results can be obtained by using computer programmes in tissues where perfusion parameters cannot be measured using traditional colour Doppler ultrasonography. Revealing the relationship between tissue perfusion and IVF success will be more effective and accurate with the development of software technologies.What are the implications of these findings for clinical practice and/or further research? To increase the success of IVF treatment, current and new technological developments, as well as imaging methods should continue to be tested.

It is a rare form of ectopic gestation and accounts for less than 1% of all pregnancies. 1 Cervical pregnancy was defined as implantation of the gestation in the endocervical canal. The incidence is approximately 1 in 2500-12000 pregnancies. 2 It is a well known complication of ART procedures. Early diagnosis is important and allows conservative treatment option to preserve fertility. Hysterectomy was the only treatment for cervical pregnancy in the past. 2 Current treatment modalities include aspiration curettage with hypogastric/uterine artery embolization, curettage and local prostoglandin injection, insertion of foley catheter in the cervical canal after curettage , local administration of methotrexate (MTX) with/without local potassium chloride, systemic administration of MTX and hysterescopic resection of the gestation in conjuction with uterine artery embolization. 3-5 Early diagnosis is important to prevent serious complications such as

IUI başarısı birçok faktöre bağlıdır. Gebelik oranlarında artış sağlamak için sıklıkla ovaryan stimülasyonla kombine edilmektedir. Değişik ovulasyon indüksiyon ajanları bu amaçla kullanılabilinir. Bu yaklaşımın mantığı, bazı hafif ovulatuar problemlerin düzeltilmesi, fertilizasyon şansının artırılması ve IUI zamanlamasının doğru yapılmasıdır. Ovulasyon indüksiyonuna gereksinim olduğunda, çoğul gebelik ve ovaryan hiperstimülasyon sendromundan kaçınmak için minimal stimülasyon rejimleri kullanılmalıdır.

IUI başarısı birçok faktöre bağlıdır. Gebelik oranlarında artış sağlamak için sıklıkla ovaryan stimülasyonla kombine edilmektedir. Değişik ovulasyon indüksiyon ajanları bu amaçla kullanılabilinir. Bu yaklaşımın mantığı, bazı hafif ovulatuar problemlerin düzeltilmesi, fertilizasyon şansının artırılması ve IUI zamanlamasının doğru yapılmasıdır. Ovulasyon indüksiyonuna gereksinim olduğunda, çoğul gebelik ve ovaryan hiperstimülasyon sendromundan kaçınmak için minimal stimülasyon rejimleri kullanılmalıdır.

G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Ege Üniversitesi Aile Planlaması ve Kısırlık Araştırma ve Uygulama Merkezinde 2008-2013 yılları arasındaki 6405 IVF siklusu retrospektif olarak tarandı. Tüm sikluslar yaş gruplarına göre 30 yaş altı (n:1870), 30-34 (n:2074), 35-39 (n:1920) ve 40 (n:541) yaş üstü olarak 4 gruba ayrıldı. Temel özellikleri, tedaviye cevap ve sonuçlar kaydedildi. B Bu ul lg gu ul la ar r: : Yaşla birlikte kullanılan ilaç dozu artmakta, indüksiyon süresi uzamakta ve oosit sayısı azalmaktadır.yaş grupları elde edilen oositler açısından karşılaştırıldığında <5 oosit elde edilenlerde yaştan bağımsız gebelik başarısı düşüktür. ≥20 oositte ovarian hiperstimülasyon riski nedeniyle transfer iptalleri artmaktadır. S So on nu uç ç: : Elde edilen 10-15 oosit aralığı başarı ve yan etki açısından en avantajlı görünen sayı olarak değerlendirilmiştir.

Gebelik planlayan kişilerde de, viral hepatit ve TORCH enfeksiyonları için serolojik testlerin değerlendirilmesi gerekir. Bu nedenle hastanemizde in vitro fertilizasyon programına alınan hastalarda bazı enfeksiyon etkenlerinin taranmasını amaçladık.
