Filter by:Luteal phase support in "in vitro fertilization" (IVF) cycles has been shown to improve pregnancy rates and became a standard of treatment, and progesterone is the first choice considering its safety profile and effectiveness. There are many studies demonstrating that vaginal progesterone is equally efficacious and better tolerated compared to intramuscular progesterone for luteal phase support in IVF cycles. Conversely, although different studies showed that subcutaneous progesterone is equally efficacious compared to vaginal progesterone, patient use satisfaction and compliance were less studied with few evidences are available, that may guide the choice of vaginal progesterone instead of subcutaneous progesterone and other way around. Considering the paucity of published data about the patient's preference and use satisfaction about subcutaneous progesterone, the investigators will conduct a prospective randomized study aimed to compared adverse effects rates, impact on quality of life, use satisfaction and administration preference in women undergoing luteal phase support with vaginal progesterone versus subcutaneous progesterone during IVF cycles, that may guide the choice for luteal phase support in IVF cycles.
Embryo Transfer With Self-spent Culture Medium or new Culture Medium in Vitro Fertilization - Embryo Transfer Process, to analyze which way can improve clinical pregnancy outcomes, is there a significant difference between the two?
Interventional studies compared electroacupuncture group versus sham electroacupuncture group to granulosa cell apoptosis index, oocyte maturation, GDF9 and BMP15 levels, and fertilization rate in in vitro fertilization program
Azathioprine increase pregnancy rate in patients with recurrent implantation failure
The purpose of the study is to evaluated whether there is a difference in pregnancy rate when transferring frozen embryos between patietns having spontaneously ovulated versus those triggered to voulate with HCG.
Between March 2016 and March 2017, we performed a large retrospective, non-interventional, single-center cohort study and measured 25(OH)D3 plasma levels prior to ovarian stimulation in couples who underwent IVF/ICSI.And we analysed the correlation of vitamin D status and reproductive capacity .
The investigators retrospectively analysed the complication rate of ultrasound guided transvaginal oocyte retrieval (TVOR) from all the procedures performed between 1996 and October 2016 in a tertiary level university based fertility clinic.
This is a randomized-controlled trial evaluating the effect of the use of hyaluronan (HA)-enriched embryo transfer medium on the live birth rate in women undergoing frozen-thawed embryo transfer. For half of the women, hyaluronan-enriched medium will be used as embryo transfer medium. For the other half of women, a control will be used.
Background: Embryo quality is known to be a very important determinant to predict the implantation and pregnancy rate in IVF patients, however, the role of uterine integrity or endometrial receptivity cannot be overlooked. Chronic endometritis (CE) is an inflammation of the endometrium diagnosed by the presence of plasma cells in the endometrial stroma. There is not only no census on the definition of CE, the current literature on the impact of CE on reproductive outcome is controversial and consists only of retrospective studies with small sample sizes. Although there is a presumption that CE is related to poor IVF outcome, this belief has not been proven. Design: Prospective cohort study Setting: Infertility clinics of 2 academic medical centers Patients: Patients between the ages of ≥ 21 and ≤ 35 years old undergoing their first IVF cycle will be invited to participate. Main Outcome Measures: The primary outcome will be ongoing pregnancy after 12 weeks estimated gestational age (EGA) with previously documented fetal cardiac motion. Secondary outcomes will include pregnancy loss rate as defined by chemical pregnancy, blighted ovum or loss of fetal cardiac motion before 12 weeks EGA. Materials and Methods: The cycle prior to IVF, patients will undergo an in-office endometrial biopsy on cycle days 19-24. Samples will be stained for CD138 and the number of plasma cells will be quantified. The number of plasma cells in a sample that yields the best sensitivity and specificity for pregnancy will be determined by a Receiver-Operator-Curve. This number will then be used as a dichotomous variable to assign categories of "positive for CE" and "negative for CE." Pregnancy and miscarriage rates will then be determined in the positive and negative CE sample with Chi Square Analysis. A secondary sub analysis will be performed to determine pregnancy and miscarriage rates in patients who declined to participate in the study. Expected Results: The investigators hypothesize that higher rates of CE will be found in women failing to conceive with IVF and with subsequent first-trimester miscarriage.
To date, several studies have been done to explore the relationship between Vitamin D level and IVF outcome; however, the results are controversial. Sample sizes in these studies mentioned above were relatively small. In addition, there are no prospective cohort studies in this field. Thus, here the investigators carry this prospective observational cohort study to demonstrate the relationship between vitamin D level and IVF outcome.
