The intracellular magnesium and calcium ion concentrations of in vivo-developed 2-cell hamster embryos were measured using ratiometric fluorometry. Intracellular magnesium and calcium ion concentrations were found to be 0.369 +/- 0.011 mM and 129.3 +

Spermatozoa and oocytes are separately formed in highly specialized biological compartments (testes and epididymis, ovarian follicle), then deposited communally in the oviduct in an environment designed to facilitate their final maturation, promote t

The behavior of golden hamster blastocysts was studied in vitro by continuous time-lapse videomicrography and computer imaging, during and immediately following escape from the zona pellucida. This study revealed numerous small cytoplasmic trophectod

Progesterone (P) is postulated to have a physiological role in vivo during sperm capacitation and/or during sperm-egg interaction as a cofactor for induction of the acrosome reaction. Effects on in vitro fertilization were tested by adding P (0.01-2

In vitro, progesterone induces capacitation, hyperactivated motility, and acrosome reactions in sperm, possibly acting through a non-genomic plasma membrane receptor, but neither progesterone functions nor concentration within the mammalian oviduct d

Previously, we found oviductal eggs to be significantly more penetrable and fertilizable in vitro than ovulated eggs collected from the ovarian bursa, while bursal eggs were comparable to mature (unovulated) follicular eggs. Incubation of follicular

Specific aims of this study were to compare relationships between size of intact antral follicles and meiotic competence, diameters, and chromatin configurations of germinal vesicle (GV) oocytes in non-gonadotropin-stimulated rhesus monkeys. Intact a

The bicarbonate: CO2 (HCO3-:CO2) concentration dependencies of hamster sperm motility, spontaneous acrosome reactions, and zona penetration (used to assay the zona-induced acrosome reaction) were examined. A cross-over experimental design was used to
