Filter by: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.
Deoxyribonucleic acid (DNA) damage of granulosa cells obtained during oocyte retrieval will be evaluated by comet assay in unexplained infertile patients undergoing in vitro fertilization (IVF) treatment. The oocytes will be graded by particular criteria. Fertilization, embryo quality, transfer rate, implantation, clinical pregnancy, pregnancy outcomes (gestational age at delivery, route of delivery, and birthweight etc.) will be recorded as well as demographic data. DNA damage of granulosa cells will be compared between unexplained infertile and control groups. The effect of DNA damage of granulosa cells on fertilization, quality of oocyte and embryo, implantation, and clinical pregnancy will be also evaluated.
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 randomized, controlled, prospective, crossover, open-label, two-treatments, two-period trial aimed to evaluate the preference expressed by the patient concerning the subcutaneous administration of progesterone versus the vaginal one. The couples, scheduled for performing 2 In Vitro Fertilization (IVF)/Intracytoplasmic Sperm Injection (ICSI) cycles will be randomized to receive, as luteal phase supplementation, Pleyris 25 milligram (mg) (a single subcutaneous administration per day) or Prometrium 200 mg (3 vaginal administrations per day).
Infertility has been estimated to affect from 6-18% of couples trying to conceive. In 20-30% of cases, the problem is with the male. Varicocele is a common cause of male factor infertility (MFI) being responsible for 30-35 % of primary and 69-81 % of secondary MFI. Varicocele repair has been shown to improve sperm parameters and increase natural pregnancy rates and the results of assisted reproductive techniques (ART). There are two possible treatment pathways for varicocele associated male factor infertility. 1) standard IVF/ICSI 2) varicocele repair followed by IVF/ICSI if there is no spontaneous pregnancy. There is however no consensus as to which pathway is preferable and no randomized comparative studies have been carried out. IVF/ICSI is a standard treatment for infertility but frequently requires repeated treatments to achieve a live birth. The purpose of this study is to determine if the improved sperm parameters caused by prior treatment of the varicocele will result in improvements both in overall pregnancy/birth rates and in IVF/ICSI results.
The primary objective of this study is to evaluate the impact of a session of virtual reality (VR) with the objective of lowering the anxiety level on the clinical pregnancy rate following an In-vitro fertilisation (IVF) procedure. Indeed, anxiety in relation to infertility happens frequently and over time, can become stressful for our patients. This level of stress influences the effect of the infertility treatment. Reducing anxiety levels could promote the ability of the patients to face this stress and promote a greater chance of pregnancy in that context.
The purpose of this study is to investigate the impact of melatonin administration on in vitro fertilization (IVF/ICSI) outcomes namely the total number and quality of the oocytes and embryos in the prospective poor responders.
The purpose of this study is to determine the impact of the use of calcium ionophore on the ICSI outcomes in couples with severe male factor infertility. Investigators conduct a randomized controlled trial on the sibling oocyte to justify the use of calcium ionophore in these cases.
