New insights on the origin and relevance of aneuploidy in human spermatozoa.

abstract：:Fluorescent in situ hybridization (FISH) studies of human preimplantation embryos have demonstrated a high proportion of chromosomal mosaicism. To investigate the different timings and nature of chromosomal mosaicism, we developed single cell multiplex fluorescent (FL)-PCR to distinguish meiotic and mitotic cell divis...

abstract：:FSH is a pituitary gonadotropin that along with LH plays a key role in the regulation of gonadal function. The gonadotropic hormones are composed of two subunits, the common alpha subunit and the hormone-specific beta subunit, which determines the binding to specific receptors and induction of biological response.
