Intracytoplasmic sperm injection in Scandinavia [PDF]

Human Reproduction, 1996
Several Scandinavian clinics are now practising intracytoplasmic sperm injection (ICSI), and our data largely resemble that published from the Brussels group (Van Steirteghem et ai., 1993). In recent meetings, Scandinavian workers have come to some mutual decisions: (i) not more than two embryos will be replaced; (ii) recombinant follicle stimulating ...

Longitudinal surface measurements of human blastocysts show that the dynamics of blastocoel expansion are associated with fertilization method and ongoing pregnancy

Reproductive Biology and Endocrinology, 2022
Background Despite all research efforts during this era of novel time-lapse morphokinetic parameters, a morphological grading system is still routinely being used for embryo selection at the blastocyst stage.

Spatially Organized Human Ovarian Spheroids Instruct Endometrial Morphogenesis

Advanced Science, EarlyView.
A spatially organized human follicle‐like spheroid (SPHEGaT) composed of granulosa cells (GCs) and stromal‐derived theca‐like cells (TLCs) establishes sustained steroidogenesis in vitro. When co‐cultured with human endometrial organoids (EMOs), estradiol (E2) and progesterone (P4) exchange induces secretory/progesterone‐responsive differentiation ...

Oocyte–cumulus cell interaction: a key factor in early embryo development

Biological Reviews, EarlyView.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.
