Polymorphisms of estrogen receptors alpha and beta in idiopathic, infertile Brazilian men: a case-control study.

abstract：:In pigs, the morphology and cell number of in vitro-produced blastocysts are inferior to those of their in vivo counterparts. The objective of this study was to increase developmental competence and to gain an understanding of cell allocation in blastocysts derived from the aggregation of four-cell stage porcine embry...
