Demi-embryos (produced by destroying 1 or 2 blastomeres of 2- or 4-cell embryos, respectively) and intact mouse embryos were cultured to the blastocyst stage, stored at -5 degrees C for 48 h, then cultured for 24 h and transferred into pseudopregnant

Bovine oocytes were vitrified (V-oocytes) or frozen slowly (S-oocytes) at the germinal vesicle (GV) stage or after maturation in vitro (IVM) and their survival assessed morphologically and also by in vitro fertilization (IVF) and culture. The morphol

The effect of supercooled storage (at subzero temperatures without ice formation) on compacted mouse morulae and early blastocysts was studied. The embryos were equilibrated with one of three storage solutions containing 1, 3, or 6% each of methanol

A new, enzyme-linked, immunosorbent assay for testosterone is described. The assay uses horseradish peroxidase coupled to testosterone as the tracer and offers the same sensitivity and reliability but greater convenience than radioimmunoassay. The as
