Filter by:The objective of this study is to determine the impact on clinical pregnancy rate of withholding routine prophylactic antibiotic therapy during IVF. The hypothesis is that withholding antibiotic prophylaxis will be non-inferior to routine administration. To test this hypothesis, the investigators will conduct a randomized controlled non inferiority trial. Additionally an exploratory study will be conducted among the first 30 patients undergoing their first cycle enrolled to evaluate the microbiome across the IVF cycle, in addition to the human virome
All patients will go through an ICSI (intracytoplasmic sperm injection)cycle Monitoring: COH (controlled ovarian hyperstimulation) will be monitored by transvaginal sonography, and then the dose of gonadotropin will be adjusted according to the follicle size and number. Triggering ovulation: when three or more follicles reach >18mm, endometrium triple line >8mm, both the gonadotropin and agonist injections will be stopped and 10,000 IU of hCG(human chorionic gonadotropin ) will be given. Egg collection : 34-36 hour after hCG injection, embryo transfer :48-72 hour after oocyte retrieval. Luteal phase support: with 100 mg progesterone injection IM daily until the day of the pregnancy test pregnancy test: 15 days after the embryo transfer. Semen collection and preparation Semen samples will be collected by masturbation in clean containers, usually after 2-3 days of abstinence. Each sample will be allowed to liquefy for at least 20 min at 37 °C. Semen analysis: Basic sperm parameters including sperm count, concentration, motility and morphology will be evaluated according to World Health Organization guidelines. After the initial assessment, ejaculates will be divided into three aliquots. An aliquot of each sample will be used to assess sperm DNA damage, the second aliquot will be processed by direct swim-up technique (n 30) or zeta test technique (n 30) this will be followed by assessment of DNA damage again in each sample to measure the difference in DNA damage after processing in each technique then spermatozoa from the third aliquot will be morphologically analyzed manually using Spermic stain and a light microscope and will be scored according to WHO
Assisted reproductive technology (ART) has extensively allowed pregnancy for infertile couples. However, the long-term effect of ART exposure on cardiovascular development and potential association with ART procedure and parental factors is confused. The aim is to shed more light on the pattern and extent of cardiovascular developmental alteration among ART children and its association with potential confounders.
For this project, 4 groups of 38 infants have been created so as to evaluate the impact of Assisted-Reproduction Technology (ART) and more particularly the two procedures classically used in ART: the freezing/thawing of embryos and prolonged embryo culture (five days of culture in appropriate in vitro conditions to allow development of the embryo) in contrast with shorter culture of only two days. Participation consists in accepting samples to be taken at the birth of the infant: 1. from the umbilical cord. 2. from the placenta.
This observational study aims the potential role of serum progesterone levels on the day of oocyte pick-up on the probability of pregnancy, in patients undergoing antagonist IVF cycles. There has been evidence, that increased serum levels of progesterone on triggering day are associated with a decreased probability of pregnancy after IVF. There is no study that investigate assocation between serum progesterone levels on the day of oocyte pick-up and IVF outcomes. This study will be the first in this case.
