Reproductive Research

Many exciting developments in mammalian reproductive research with far-reaching consequences have occurred in recent years. To highlight the significance of some of these developments, a symposium on the theme of ovarian follicular development and regression was organized, and held at the joint meeting of the American Physiological Society and the Canadian Physiological Society, in Montréal in October 1988. Several leading researchers, from both Canada and the U.S.A., in various aspects of ovarian research, participated in the symposium. The topics of discussion ranged from the role of growth factors and novel intraovarian regulators during follicular development, to molecular aspects of ovarian hormone production, to the functional regression of the corpus luteum. It is expected that the following proceedings will serve as a reference for researchers concerned with reproductive endocrinology as well as providing a foundation for future collaborative study.

Eur J Endocrinol 1996;134:649–54. ISSN 0804–4643 The aim of this study was to examine the effects of prepubertal hypothyroidism on ovarian development in rats. Therefore, from birth up to day 40 postpartum, rats were given 6-propyl-2-thiouracil (PTU) via the drinking water of mothers and pups. At ages ranging from 12 to 40 days, ovarian weights were measured and serum was collected to estimate thyrotrophin (TSH), folliclestimulating hormone (FSH) and inhibin levels. Two hours before sacrifice the animals received an injection of bromodeoxyuridine (BrdU) to estimate the proliferative activity of the follicular granulosa cells. Ovaries were fixed in Carnoy's fluid and follicle counts were performed on sections stained with anti-BrdU and with haematoxylin and eosin. The PTU treatment resulted in increased serum TSH levels, indicative of hypothyroidism, and markedly lower body and ovarian weights, whereas serum FSH and inhibin levels were hardly affected. At day 40, ovaries of PTU-treated animals contained relatively more secondary and less antral follicles, smaller non-atretic antral follicles and more atretic follicles when compared with untreated rats, while corpora lutea were absent. It is concluded that this disturbed folliculogenesis is due to inadequate thyroid hormone supply, which hampers the differentiation and not the proliferation of granulosa cells because diameters of antral follicles were significantly smaller whereas the BrdU-labelling index had not changed.

Self Learning

Over the past 10 years, college textbooks in human anatomy and physiology have typically presented the events of the ovulatory menstrual cycle in a linear format, with time in days shown on the x-axis, and hormone levels, follicular development, and uterine lining on the y-axis. In addition, the various events are often shown over a 28-day cycle, when they can take place over 21–35 days and may not be regular at all. Here, we propose a circular diagram that is independent of a set cycle time and readily shows the cyclic nature of the events. This diagram can be presented sequentially in organized layers, and additional complexity can be added. In addition, we present questions here that can promote self-learning before and critical thinking after the discussion of the cycle to enhance understanding of the physiological events.
