BACKGROUND Early prenatal androgenization (PA) accelerates follicle differentiation and impairs embryogenesis in adult female rhesus monkeys (Macaca mulatta) undergoing FSH therapy for IVF. To determine whether androgen excess in utero affects follic

Experimentally induced fetal androgen excess induces polycystic ovary syndrome-like traits in adult female rhesus monkeys (Macaca mulatta). Developmental changes leading to this endocrinopathy are not known. We therefore studied 15 time-mated, gravid

GnRH II (pGlu-His-Trp-Ser-Try-Gly-Leu-Arg-Pro-GlyNH2), an evolutionarily conserved member of the GnRH family, stimulates reproductive behavior in a number of vertebrates. To explore a role for GnRH II in regulating primate sexual behavior, eight adul

During the ovarian or menstrual cycle, prior to ovulation, many female primates exhibit a relatively prolonged follicular phase and terminate the postovulatory luteal phase with menstrual bleeding. The prolonged follicular phase is a trait that disti

The hfa (high frequency of aneuploidy) mutants of Aspergillus nidulans carry conditional lethal (temperature-sensitive) defects which cause an increased frequency of aneuploids to be produced amongst their asexual progeny. When examined microscopical

While perinuclear clustering of active mitochondria, as revealed by Rhodamine 123 staining and confocal microscopy, is part of normal hamster embryo development, it is not known whether this reorganization is necessary for development. To determine i

Hamster embryos cannot complete the second cleavage division in vitro in the presence of glucose and inorganic phosphate (Glu/Pi). Embryos can recover from an 8 h (12:30-20:30 h) exposure to Glu/Pi, although cleavage is retarded by 10 h and continued

The role of mitochondrial metabolism in the development of preimplantation embryos is unclear. To clarify the importance of mitochondria in early development, the fluorescent probes rhodamine 123 (Rh123: stains active mitochondrial membrane) and nony

Discrete fetal androgen excess during early gestation in rhesus monkeys ( Macaca mulatta ) promotes endocrine antecedents of adult polycystic ovary syndrome (PCOS)-like traits in female offspring. Because developmental changes promoting such PCOS-lik
