Ninety-two dairy cows milking 23 I milk/day at the time of superovulation and belonging to the main domestic breeds were used in this study. Their mean age was 5.5 years and they had calved a mean 3.6 times. In 71 animals the previous calving interval was 369 days, and the calving-superovulation interval was 126 days. The cows were superovulated with 1 500 to 3 000 IU of PMSG (mean of 2 400 IU) on days 8 to 13 of the estrous cycle (mean of 10.7 days), followed 48 to 60 hrs (mean of 52 hrs) later by cloprostenol treatment (0.5 mg). The mean interval from PMSG injection to heat was 4.1 days, and that from the cloprostenol treatment was 45.5 hrs. A total of 6.0 embryos/donor were nonsurgically recovered at the farm on days 6 to 8 (mean of 7.1 days).

Summary. High concentrations of catecholamine-containing axons have been observed with the Falck-Hillarp technique in the hypothalamus of squirrel monkeys, namely in the periventricular area, preoptic nucleus, arcuate nucleus, premammillary area and dorso medial nucleus. Catecholamine-containing cell bodies were not found routinely in all animals but have been observed in some of them within the medio-basal hypothalamus and the postero-dorsal and rostral hypothalamic areas. This topography suggests that of the A12, A13, and A14 groups, previously described in other mammalian species.

This communication reviews the current information on the developmental relationships between the various tissues of the growing human antral follicle. It also examines the various interrelationships between the hormone levels in antral fluid, the populations of granulosa cells, the steroidogenic capacities of thecal tissue and granulosa cells, and the status of the oocyte in antral follicles at different stages of growth or degeneration. Healthy antral follicles are considered to be those containing an oocyte which appears healthy at the level of the dissecting microscope and more than 50 p. 100 of its full complement of granulosa cells at each follicle diameter. In follicles with more than 75 p. 100 of their full complement of granulosa cells,’at a given follicle diameter, the endocrine microenvironment is one that is enriched with FSH and cestradiol. Follicles with between 51 and 75 p. 100 of their full complement of granulosa cells at a given follicle diameter are inva-

The secretion of follicle stimulating hormone (FSH) and luteinizing hormone (LH) is partly regulated by a non-steroid factor, inhibin, present in the testicular lymph and rete testis fluid (RTF). We were interested to know whether the RTF excreted into the epididymis has a regulatory role on the secretion of FSH and LH. The remaining rete testis of 6 adult rams hemicastrated 6 to 10 months earlier was cannulated. These rams were castrated either the day after the flow of RTF spontaneously stopped or 15 days after cannulation if the cannula was still functional. Two daily blood samples were taken from 7 days before cannulation to 7 days after castration and circulating levels of FSH, LH and testosterone were measured. Rete testis cannulation did not affect FSH, LH or testosterone plasma levels, although castration induced a sudden decrease in testosterone concentration and a rapid increase in FSH and LH levels. The present results suggest that the inhibin present in the RTF excreted into the epididymis does not play any role in the regulation of FSH and LH secretion. These hormones could be regulated by the inhibin present in the efferent circulation (lymph or blood) from the testis.
