Uterine contractility decreases at the time of blastocyst transfer.
Uterine contractility decreases at the time of blastocyst transfer Dear Sir, Fanchin and co-workers (Fanchin et al., 2001) should be congratulated for publishing a very well written paper on the role of uterine contractions in assisted reproduction. They provide convincing evidence that uterine contractility at the time of theoretical blastocyst transfer (7 days after HCG injections or 5 days a...
متن کاملUterine contractility decreases at the time of blastocyst transfers.
High-frequency uterine contractions at the time of non-cavitating embryo transfer influence adversely IVF-embryo transfer outcome. This prompted us to quantify prospectively the possible decline in uterine contraction frequency occurring during later stages of the luteal phase of ovarian stimulation, up to the time of blastocyst transfers, in 43 IVF-embryo transfer candidates. Contractility was...
متن کاملTargeted gene transfer increases contractility and decreases oxygen cost of contractility in normal rat hearts.
The aim of this study was to examine how global cardiac gene transfer of sarcoplasmic reticulum Ca(2+)-ATPase (SERCA2a) can influence left ventricular (LV) mechanical and energetic function, especially in terms of O(2) cost of LV contractility, in normal rats. Normal rats were randomized to receive an adenovirus carrying the SERCA2a (SERCA) or beta-galactosidase (beta-Gal) gene or saline by a c...
متن کاملMonozygotic twins and transfer at the blastocyst stage after ICSI.
The incidence of monozygotic twinning (MZT) is higher in pregnancies conceived after assisted reproduction than after natural conception. Alterations, produced by ovarian stimulation, in-vitro culture conditions and specifically alterations of zona pellucida are mentioned as possible causes of this phenomenon. A retrospective review was performed of the incidence of MZT in pregnancies generated...
متن کاملTime to switch from co-culture to sequential defined media for transfer at the blastocyst stage.
It is current practice in in-vitro fertilization (IVF) to transfer embryos 48 h post-insemination at the 2–4 cell stage. However, it is now clear that this is a totally blind process. Firstly, embryos encounter an unsuitable environment, normally they would be in the oviduct. Secondly, motility of the uterus is related inversely to circulating progesterone. This problem of hypermotility of the ...
