during assisted reproductive technology (art) procedures, the transfer of a single embryo dramatically reduces the rate of multiple pregnancy. proper information, therefore, should be delivered to patients before embryo transfer. in many countries, regulations limit, according to age of the patient, the number of embryos to be transferred. selective fetal reduction should not be considered as a...

Direct selection for ovulation rate, uterine capacity, litter size and embryo survival and selection for indexes of ovulation rate with each of the remaining traits were simulated for a swine population. The relationships among these traits were determined from a simulation model that assumed that litter size was always less than or equal to both ovulation rate and uterine capacity. Heritabilit...

Recipient age at transfer (less than 525 d old or more than 525 d old), season (fail, winter, spring, summer), method of synchronization (natural or induced), and transfer technique (surgical or nonsurgical transfer) were associated with success of embryo transfer in a log-linear analysis. In a separate analysis, no significant association was found between success of transfer and transfer to t...

The activity of mouse endometrial alkaline phosphatase after hyperstimulation and progesterone injection at the implantation time Alkaline phosphatase (ALP) of endometrium may play a critical function in the development and implantation of embryo. The aim of this study was to determine the localization of endometrial ALP activity after hyperstimulation and progesterone injection. Thirty adult f...

OBJECTIVE To determine reproductive outcome after in-vitro fertilization/embryo transfer (IVF-ET) in women with primary infertility following hysteroscopic septoplasty of incomplete uterine septum or arcuate uterine anomaly. METHODS This is a historical cohort study. The study group consisted of 156 consecutive patients who underwent a total of 221 cycles of IVF/ET following hysteroscopic sep...

BACKGROUND Infertility is a common problem affecting up to ten per cent of married couples. A systematic evaluation of aetiologic factors forms the basis for choice of treatment and future fertility. On the global perspective, Assisted Reproductive Technologies (ART) has become internationally recognised treatment option for some infertile couples. A report on the current outcomes of ART practi...

BACKGROUND The currently low implantation rate after embryo transfer (ET) is partially attributed to technical aspects, such as catheter type, catheter load, placement of catheter tip and physician skills. METHODS Mock ET simulations were conducted with a transparent laboratory model of the uterine cavity. The catheter was loaded with alternating air and coloured liquid media. The transfer pr...
