SUMMARY Adult rats which had been previously sterilized by means of X-rays were hypophysectomized a fortnight after the onset of continuous vaginal cornification (which begins within 40 days of X-irradiation [Mandl & Zuckerman, 1956]). The animals, i

The total number of oocytes in the ovaries of the rat decreases with age, the relation between the two variates conforming to the exponential relation y = axb. The regression of oocyte numbers on age is defined by the equations log y = 4·334 − 0·

Treatment of intact immature rats with heavy doses of a purified preparation of norethynodrel (containing ca. 0.17% of ethinyl estradiol-3-methyl ether) did not inhibit, and may have marginally enhanced, ovarian sensitivity to exogenous gonadotrophic

A cytological and quantitative study was made of the testes of foetal and neonatal rats. The population of germ cells was estimated for a total of 111 specimens. A volumetric method (Beaumont & Mandl, 1962) was used for animals aged 14.5 days p.c. to

The viability of the zygote after fertile mating has been used as an index to assess the radio-sensitivity of oocytes in Graafian follicles at different times before expected ovulation, and at known stages of the maturation process. Radio-sensitivity

All medium and large follicles were counted and measured in twenty-four pairs of ovaries belonging to rats killed at seven different phases of the oestrous cycle. The follicles were classified into seven size groups, and their frequency distribution
