BACKGROUND The development of an accurate method for selection of high-quality embryos
is essential to achieve high pregnancy rates with single embryo transfer in human IVF. …

We report here that intracellular pH (pH i ) in cleavage-stage human embryos (2–8-cell) is
regulated by at least two mechanisms: the HCO 3 – /Cl – exchanger (relieves alkalosis) and …

Embryo selection efficiency in human IVF procedure is still suboptimal as shown by low
pregnancy rates with single embryo transfer (SET). Bidirectional communication between the …

OBJECTIVE: To assess the association between in vitro fertilization (IVF) with or without
intracytoplasmic sperm injection (ICSI) and adverse birth outcomes. STUDY DESIGN: …

Sperm cryopreservation has been widely used in assisted reproductive technology (ART)
and has resulted in millions of live births. Two principal approaches have been adopted: …

Multiple pregnancy represents an important health risk to both mother and child in fertility
treatment. To reduce a high twin rate, restriction to one embryo transfer is needed. …

Using an antiserum raised against hamster oviductal zona pellucida, we observed specific
immunogenic components of the reproductive tract on the zonae of oviductal eggs and in …

Objective: To evaluate the usefulness of morphology grading of the oocyte-corona-cumulus
complex (OCCC) as a marker of oocyte nuclear maturity, fertilizability, embryo cleavage, and …

Purpose Hormonal stimulation prior to IVF influences the ovarian environment and therefore
impacts oocytes and subsequent embryo quality. Not every patient has the same response …

OBJECTIVE: To test whether the probability of having a live birth (LB) with the first IVF cycle (C1)
can be predicted and personalized for patients in diverse environments. DESIGN: …
