Introduction: Intrauterine insemination technique is one of the most commonly used methods in assisted reproductive treatments. Semen parameters are one of the prognostic factors affecting the clinical success of the intrauterine insemination method, and different sperm preparation techniques are applied to select quality sperm.
Methods: In this retrospective study, 217 couples who applied to the infertility center of our hospital between 2012 and 2020 were included in the study. Before the application of the intrauterine insemination method, semen samples taken from 178 patients were prepared by microchip method and semen samples taken from 39 patients were prepared by density gradient centrifugation method, and the concentration and motility properties of sperm were evaluated. Results: The clinical pregnancy success of sperm samples prepared with microchip and density gradient centrifugation method was evaluated after intrauterine insemination application. In the density gradient centrifugation method, motile sperm (79.46±12.48%) were obtained at a higher rate than the microchip method (57.48±20.24). While clinical pregnancy was observed in 46.15% of the patients included in the density gradient centrifugation group, it was determined as 23.03% in the microchip group. On the other hand, while pregnancy continued in 27.78% of the density gradient centrifugation group patients, the continuing pregnancy in the microchip group was determined as 53.66%. As a result, while the percentage of motile sperm and the incidence of clinical pregnancy increase in the density gradient centrifugation method compared to the microchip method, there is a significant decrease in the ongoing pregnancy rates.
Conclusions: It is seen that sperm samples prepared by microchip method have positive contributions to the clinical success of intrauterine insemination.

Intrauterin İnseminasyonda Dansite Gradiyent Santrifügasyon ve Mikroçip Sperm Hazırlama Yöntemlerinin Gebelik

Öz

Giriş: Intrauterin inseminasyon tekniği yardımcı üreme tedavilerinde en sık kullanılan yöntemlerden biridir. Semen parametreleri intrauterin inseminasyon yönteminin klinik başarısını etkileyen prognostik faktörlerin başında gelmektedir ve kaliteli spermlerin seçilimi için farklı sperm hazırlama teknikleri uygulanmaktadır.
Yöntemler: Bu retrospektif çalışmada 2012 ve 2020 yılları arasında hastanemiz infertilite merkezine başvuran 217 çift çalışma kapsamına alınmıştır. Intrauterin inseminasyon yönteminin uygulaması öncesi 178 hastadan alınan semen örnekleri mikroçip yöntemi ve 39 hastadan alınan semen örnekleri dansite gradiyent santrifügasyon yöntemi ile hazırlanmış ve spermlerin konsantrasyonu ve motilite özellikleri değerlendirilmiştir. Intrauterin inseminasyon uygulaması sonrası mikroçip ve dansite gradiyent santrifügasyon yöntemi ile hazırlanan sperm örneklerinin klinik gebelik başarısı değerlendirilmiştir.
Bulgular: Dansite gradiyent santrifügasyon yönteminde motil sperm (%79.46±12.48) mikroçip yöntemine göre (%57.48±20,24) daha yüksek oranda elde edilmiştir. Dansite gradiyent santrifügasyon grubuna dâhil olan hastaların %46.15’ünde klinik gebelik gözlenirken mikroçip grubunda %23.03 olarak belirlenmiştir. Buna karşın dansite gradiyent santrifügasyon grubu hastaların %27.78’inde gebelik devam ederken mikroçip grubunda devam eden gebelik %53.66 olarak belirlenmiştir. Sonuç olarak mikroçip yöntemine kıyasla dansite gradiyent santrifügasyon yönteminde motil sperm yüzdesi ve klinik gebelik görülme oranı artarken, devam eden gebelik oranlarında ciddi oranda azalma görülmektedir.
Sonuç: Mikroçip yöntemi hazırlanan sperm örnekleri intrauterin inseminasyon’nun klinik başarısı üzerine olumlu katkılar verdiği görülmektedir.
