Filter by:This study evaluated whether laser acupuncture at the time of embryo transfer (following in vitro fertilization) improves implantation rates. Patients were randomized to one of 4 groups at the time of embryo transfer: 1) laser acupuncture, 2) needle acupuncture, 3) sham laser acupuncture, 4) no treatment.
Both hereditary and acquired thrombophilia have been associated with recurrent miscarriage and pregnancy complications. Thrombophilia could favor the development of thrombosis of the maternal vasculature and obstacle placentation. Some studies have suggested a role of thrombophilia in the failure of assisted reproductive techniques although this association has been recently questioned. The scope of this study is to evaluate the effect of thrombophilia on the implantation rate and live birth rate in women undergoing ART. Design: prospective, observational study Primary end-point: live birth rate. Secondary end-points: implantation rate, venous thromboembolic events during ART up to 6 weeks post-partum
The main factors associated with pregnancy rate in In Vitro Fertilization (IVF) treatment are embryo quality and the uterine ability to accept the embryo for implantation. This ability is influenced by uterine contractions (UC), which change in pattern and direction during the menstrual cycle. An abnormal uterine contraction pattern can displace the embryo from the proper position in the uterine cavity towards the cervix or the fallopian tubes and as a result may decrease pregnancy rates and increase the risk of ectopic pregnancy. Indeed, previous studies demonstrated a negative correlation between uterine contraction rate and implantation/pregnancy rates. Suppression of uterine contractions during embryo transfer can be achieved by a large array of drugs, such as cyclo-oxygenase inhibitors, β2-adrenoreceptor agonists, calcium-channel blockers, phosphodiesterase inhibitors and oxytocin antagonists. The objective of this study is to evaluate the efficacy of Nifedipine administration in reducing uterine contractility during IVF-frozen embryo transfer (FET) treatment.
The aim of the study is to determine whether 5 or 7 days of progesterone supplementation before transfer of a day 5 cryopreserved thawed embryos in an artificial cycle results in a significant higher pregnancy rate.
This prospective and randomized study was performed to evaluate whether the replacement of GnRH agonist by a GnRH antagonist in oocyte donation recipients during endometrial preparation has any impact on pregnancy and implantation rates.
Hypothesis: a special solution for improving human embryo implantation, when added to the solution during embryo transfer, will improve implantation rates in embryo transfers using previously frozen embryos.
The purpose of this study is to determine whether endometrial receptivity markers obtained by endometrial sampling are effective in prediction of in vivo human embryo implantation.
