Influence of housing conditions from weaning to adulthood on the ventilatory, thermoregulatory, and endocrine responses to hypoxia of adult female rats
Housing conditions affect animal physiology. We previously showed that the hypoxic ventilatory and thermoregulatory responses to hypoxia of adult male rats housed in triads during the juvenile period (postnatal day 21 to adulthood) were significantly reduced compared with animals housed in pairs. Because sex hormones influence development and responsiveness to environmental stressors, this study investigated the impact of housing on the respiratory and thermoregulatory physiology of female rats. Since neonatal stress attenuates the hypoxic ventilatory response (HVR) of female rats at adulthood, experiments were performed both on control (undisturbed) animals and rats subjected to neonatal maternal separation (NMS; 3 h/day, postnatal days 3ndash;12). At adulthood, ventilatory activity wa...
The value of anti-Mullerian hormone measurement in the long GnRH agonist protocol: association with ovarian response and gonadotrophin-dose adjustments
CONCLUSION
The serum AMH concentration at the start of the stimulation in IVF patients down-regulated with GnRH agonist in the long protocol revealed a positive relationship with ovarian response to gonadotrophins in terms of oocytes retrieved and accompanying endocrine response. AMH is a good predictor of the need for gonadotrophin-dose adjustment on stimulation day 6 for patients with a fixed starting dose, but a poor predictor of embryo quality and pregnancy chances in individual patients.
