Abstract

Objective: Endometriosis is a complex gynaecological condition associated with infertility; however, the impact of endometriosis on assisted reproductive technology (ART) outcomes remains unclear. The objective of this study was to compare the outcomes of in vitro fertilization (IVF) between women with endometriosis and those with tubal factor infertility and to evaluate whether significant differences exist between the groups in terms of fertilization rate, embryo development, and live birth rate.
Methods: The present retrospective observational study comprised 50 women diagnosed with endometriosis and 57 women with tubal factor infertility who underwent embryo transfer at a single fertility centre between 2017 and 2024. Patients with incomplete data, polycystic ovary syndrome, poor ovarian response, uterine myomas, or ovulatory factor infertility were excluded from the study. The collected variables included female and male ages, endometrial thickness, semen parameters (total sperm count and motility), total oocytes retrieved, metaphase II oocyte count, fertilization rate, embryo quality on days 2 and 3, blastocyst number, embryo transfer day, total embryos, biochemical pregnancy (hCG positivity), and live birth outcomes. The fertilization rate was calculated as the ratio of 2PN oocytes to total oocytes retrieved. Statistical analyses were performed using SPSS 20. Continuous variables were compared using Student's t-test or the Mann–Whitney U test, while categorical variables were analysed using Chi-square or Fisher's exact test. Statistical significance was defined as a p-value less than 0.05.
Results: Female and male ages, endometrial thickness, and total sperm count were comparable between the groups (p>0.05). No significant differences were observed in total oocyte and mature (MII) oocyte numbers, fertilization rate, day 2 and day 3 embryo quality, blastocyst count, embryo transfer day, or total number of embryos (p>0.05). Biochemical pregnancy and live birth rates were slightly higher in women with endometriosis compared to the control group, but these differences were not statistically significant (p>0.05). Sperm motility and the incidence of asthenozoospermia were also similar between the groups (p>0.05). These findings indicate that, in women with endometriosis, appropriate laboratory conditions and protocol implementation may minimize potential factors that could adversely affect ART outcomes.
Conclusion: A comparative analysis of assisted reproductive technology (ART) outcomes in women diagnosed with endometriosis and women with tubal factor infertility reveals no significant disparities in fertilisation, embryo development, and live birth rates. These findings suggest that, under well-controlled laboratory conditions and among relatively young patients, the adverse effects of endometriosis on ART success may be mitigated. Standardised protocols and judicious patient selection are imperative to optimise reproductive outcomes in this demographic. The present study demonstrates that the success of assisted reproductive technology (ART) in women with endometriosis can reach levels comparable to those with tubal factor infertility, thus providing a promising perspective for clinical practice.

Abstract

Amaç: Endometriozis, infertilite ile ilişkili karmaşık bir jinekolojik durumdur, ancak endometriozisin yardımcı üreme teknolojisi (YÜT) sonuçları üzerindeki etkisi hala belirsizdir. Bu çalışma, endometriozisli kadınlar ile tübal faktör infertilitesi olan kadınlar arasında in vitro fertilizasyon (IVF) sonuçlarını karşılaştırmayı ve iki grup arasında fertilizasyon oranı, embriyo gelişimi ve canlı doğum oranları açısından anlamlı farklılık olup olmadığını değerlendirmeyi hedeflemiştir.
Yöntemler: Bu retrospektif gözlemsel çalışma, 2017 ile 2024 yılları arasında tek bir tüp bebek merkezinde embriyo transferi yapılan, endometriozis tanısı konmuş 50 kadın ve tübal faktör infertilitesi olan 57 kadını içermektedir. Verileri eksik olan, polikistik over sendromu, zayıf over yanıtı, uterus miyomları veya ovulatuar faktör infertilitesi olan hastalar çalışma dışında tutulmuştur. İncelenen değişkenler; kadın ve erkek yaşları, endometrial kalınlık, semen parametreleri (toplam sperm sayısı ve hareketliliği), elde edilen toplam oosit sayısı, metafaz II oosit sayısı, döllenme oranı, 2. ve 3. günlerdeki embriyo kalitesi, blastokist sayısı, embriyo transfer günü, toplam embriyo sayısı, biyokimyasal gebelik (hCG pozitifliği) ve canlı doğum sonuçlarıdır. Döllenme oranı, 2PN oositlerin toplam elde edilen oositlere oranı olarak hesaplandı. İstatistiksel analizler SPSS 20 kullanılarak yapıldı. Sürekli değişkenler Student's t-testi veya Mann-Whitney U testi ile karşılaştırılırken, kategorik değişkenler Ki-kare veya Fisher'in kesin testi kullanılarak analiz edilmiştir. p-değeri <0,05 istatistiksel olarak anlamlı kabul edilmiştir.
Bulgular: Kadın ve erkek yaşları, endometriyal kalınlık ve toplam sperm sayısı gruplar arasında benzerdi (p>0,05). Toplam oosit ve olgun (MII) oosit sayısı, fertilizasyon oranı, 2. ve 3. gün embriyo kalitesi, blastokist sayısı, embriyo transfer günü ve toplam embriyo sayısında gruplar arasında anlamlı fark gözlenmedi (p>0,05). Biyokimyasal gebelik ve canlı doğum oranları endometriozisli kadınlarda kontrol grubuna kıyaslabiraz daha yüksek olmasına rağmen, fark istatistiksel olarak anlamlı değildi (p>0,05). Sperm motilitesi ve astenozoospermi insidansı dagruplar arasında farklılık göstermedi (p>0,05). Bulgular, endometriozisli kadınlarda uygun laboratuvar koşulları ve protokol uygulamalarının,YÜT başarısını olumsuz etkileyebilecek potansiyel faktörleri en aza indirebileceğini göstermektedir.
Sonuç: Endometriozis tanısı bulunan kadınların YÜT sonuçları, tübal faktör infertilitesi olan kadınlarla karşılaştırıldığında döllenme, embriyo gelişimi ve canlı doğum oranları yönünden benzerlik göstermiştir. Bu sonuçlar, iyi kontrol edilen laboratuvar ortamı ve nispeten genç hasta grubunda, endometriozisin YÜT başarısı üzerindeki olumsuz etkilerinin hafifletilebileceğini göstermektedir. Standartlaştırılmış protokoller ve özenli hasta seçimi, bu popülasyonda üreme sonuçlarını iyileştirmek için kritik öneme sahiptir. Bu çalışma, endometriozisli kadınlarda YÜT başarısının tübal faktör infertilitesi ile eşdeğer seviyelere ulaşabileceğini ortaya koyarak, klinik uygulamalara umut verici bir perspektif sunmaktadır.
