سابقه و هدف: اگرچه امروزه IVF به عنوان یک تکنیک پرکاربرد در درمان ناباروری میباشد، اما مطابق مطالعات صورت گرفته، استرس ایجاد شده به واسطهی تغییرات اسمزی، اکسیژن، دما و pH در شرایط خارج از رحم میتواند باعث تغییرات مورفولوژیکی، ژنتیکی و اپیژنتیکی در جنینهای برونتنی نسبت به حالت درونتنی گردد. هدف از این مطالعه، بررسی تاثیر IVF بر کیفیت جنینها از طریق ارزیابی نرخ زندهمانی و رشد و همچنین...
BACKGROUND The introduction of mild cycle IVF adds to the repertoire of fertility treatments. However, its place is still novel and is contested within the literature. Women's experiences of mild cycle IVF have received minimal attention. The aim of the study was to explore women's perspectives regarding mild cycle IVF. METHODS In this qualitative thematic analysis study, 17 women, and 2 part...
STUDY QUESTION Does ovarian hyperstimulation, the in vitro procedure, or a combination of these two negatively influence blood pressure (BP) and anthropometrics of 4-year-old children born following IVF? SUMMARY ANSWER Higher systolic blood pressure (SBP) percentiles were found in 4-year-old children born following conventional IVF with ovarian hyperstimulation compared with children born fol...
The use of acupuncture to improve the outcome of in vitro fertilisation (IVF) has become widespread over the past five years. Three of four randomised controlled trials (RCT) published since 2002 have shown that acupuncture significantly increases pregnancy rates. Although the research has a number of methodological limitations, it does strongly endorse the use of acupuncture during IVF. Protoc...
BACKGROUND There are several studies that have shown an increased risk of premature birth and developmental abnormalities with in vitro fertilization (IVF); however, the data on preterm mortality and morbidity are limited. AIM Our aim is to investigate whether IVF had an effect on the mortality and morbidity in neonates admitted to the neonatal intensive care unit. METHODS A total of 940 te...
In singleton pregnancies after in-vitro fertilization (IVF), increased rates of obstetric and perinatal complications have been reported. Studies that compared IVF twin pregnancies with spontaneously conceived twins have yielded conflicting results. We compared 96 IVF twin pregnancies to 96 controls after elaborate matching. The design of our study precluded matching by zygosity. The monozygosi...
OBJECTIVE Many studies have demonstrated that hydrosalpinx has a detrimental effect on the outcome of IVF. Treating hydrosalpinges prior to the IVF procedure in women with hydrosalpinges is thought to improve the likelihood of successful IVF outcome. Vaginal ultrasound-guided aspiration of hydrosalpinx fluid (HSF) with injection of the sclerosing agent in situ might be simpler than invasive pro...
OBJECTIVE To evaluate if in vitro fertilization (IVF) with embryo cryopreservation can be proposed to patients immediately after one or two regimens of chemotherapy. DESIGN Retrospective study. SETTING Academic research center and IVF unit. PATIENT(S) Eleven young patients diagnosed with cancer between September 1999 and April 2003 who wanted to preserve their fertility via IVF. INTERVE...
This study was conducted to compare the efficacy of four in vitro fertilization (IVF) media: Bracket and Oliphant's medium (BO), modified medium 199 (IVF-M199), modified Tyrode's medium (MTM), and modified KSOM (m-KSOM) on fertilization efficiency and blastocyst formation rate. In addition, we wanted to investigate the benefit of prolonging the IVF period (from 6 to 18 h) using the two most eff...
This study aimed to investigate the polymorphism of matrix metalloproteinase -3 (MMP-3) gene and its expression in the serum of infertile female patients received in vitro fertilization and embryo transfer (IVF-ET). To do so, 100 women with unsuccessful IVF-ET (IVF–) and 100 women with successful IVF-ET procedure and clinical pregnancy (IVF+) were included. Genetic polymorphism and serum concen...
