Artificial oocyte activation with calcium ionophore for frozen sperm cycles
Karabulut, Seda; Aksünger, Özlem; Ata, Can; Sağıroğlu, Yusuf; Keskin, İlknur (Taylor and Francis Ltd., 2018)Fertilization problems are the major problems that may be faced in 30-55% of the patients during an intracytoplasmic sperm injection (ICSI) cycle. A successful oocyte activation depends on factors related to both sperm and ... -
Chronic unpredictable stress disturbs the blood-testis barrier affecting sperm parameters in mice
Kolbaşı, Bircan; Bülbül, Muhammet Volkan; Karabulut, Seda; Erdem Altun, Ceren; Çakıcı, Çağrı; Ülfer, Gözde; Müdok, Tangül; Keskin, İlknur (Elsevier Ltd, 2021)Research question: Does chronic stress affect the key proteins and sperm parameters of the blood & ndash;testis barrier (BTB)? Design: C57Bl/6 mice were divided into two groups: a non-treated control group and a chronic ... -
Does a microfluidic chip for sperm sorting have a positive add-on effect on laboratory and clinical outcomes of intracytoplasmic sperm injection cycles? A sibling oocyte study
Yalçınkaya Kalyan, Ender; Can Çelik, Seren; Okan, Özlem; Akdeniz, Gülden; Karabulut, Seda; Çalışkan, Eray (Wiley, 2019)The most recent technologies for sperm sorting involve microfluidics. However, the most important question whether their use is of any advantage in terms of laboratory and clinical IVF/ICSI outcomes still remains controversy. ... -

Effects o follicular fluid oxidative status on human mural granulosa cells, oocyte competency and ICSI parameters
Karabulut, Seda; Korkmaz, Oya; Kutlu, Pelin; Eren Gözel, Hilal; Keskin, İlknur (Elsevier, 2020)Purpose: The aim of the present study was to understand the molecular and genetic alterations involved in follicular fluid oxidative process by investigating human mural granulosa cells and to find possible biomarkers for ... -
Effects of density gradient sperm preparation on semen parameters and acrosomal status
Keskin, İlknur; Karabulut, Seda (Haydarpaşa Sample Training and Research Hospital, 2017)AbstractIntroduction: The aim of this study was to observe changes in sperm parameters after density gradient sperm preparation. These data will help to decide upon preparation technique and to predict the outcome of semen ... -
Effects of human sperm cryopreservation on apoptotic markers in normozoospermic and non-normozoospermic patients
Karabulut, Seda; Demiroğlu Zergeroğlu, Asuman; Yılmaz, Elif; Kutlu, Pelin; Keskin, Ilknur (Cambridge University Press, 2018)The negative effects of cryopreservation on sperm parameters are well documented but little information is known about molecular basis of the process. The aim of the present study was to investigate the possible effects ... -
Factors related to follicular oxidative stress in intracytoplasmic sperm injection cycles and its effects on granulosa cells
Karabulut, Seda; Korkmaz, Oya; Kutlu, Pelin; Keskin, İlknur (Cambridge University Press, 2021)The aim of the present study was to investigate several common conditions that may potentially be correlated with follicular oxidative status during an intracytoplasmic sperm injection (ICSI) cycle and that include the ... -
Male infertility, azoozpermia and cryptozoospermia incidence among three infertility clinics in Turkey
Karabulut, Seda; Keskin, İlknur; Kutlu, Pelin; Delikara, Nuri; Atvar, Özhan; Öztürk, Metin İshak (AVES İbrahim Kara, 2018)Objective: Semen parameters are directly correlated with the infertility of the male.
