RESUMO
PIP: This study aimed to determine the correlation between endometrial biopsy and serum progesterone level in prediction of corpus luteum function in regularly menstruating women. Endometrial biopsy specimens were obtained from 40 women 20-25 years old with unproven fertility 2-3 days before the anticipated onset of menses. A simultaneous blood sample was obtained for measurement of serum progesterone levels using a radioimmunoassay technique. 27 biopsies were considered to be in-phase (IP) by histologic criteria, and the remaining 13 were out-of-phase (OOP). The mean serum progesterone level obtained from women with OOP biopsies 3-4 days before onset of menses was significantly lower than that obtained 1-2 days before the onset of menses. Menstruation occurred in women with OOP biopsies at a time when serum progesterone level was apparently rising. On the other hand, values were too small to identify any significant difference between groups of women with IP and OOP biopsies when these biopsies were performed very late in the cycle. The author states the importance of evaluating both serum progesterone and endometrial biopsy dating in the late luteal phase of the menstrual cycle. Serum progesterone was easy to perform, while endometrial biopsy showed the end result.^ieng

Estrone, estradiol, estriol, progesterone, 17 alpha-hydroxyprogesterone, testosterone, and dihydrotestosterone levels were determined in sera of 20 fertile men and 15 male patients with Sertoli cell only syndrome. In men with Sertoli cel only syndrome there was a significant decrease in serum estrone, estradiol, progesterone, 17 alpha-hydroxyprogesterone, and dihydrotestosterone and a significant increase in serum estriol and testosterone. Changes in endocrine profile discussed in relation to the possible role of inhibin.

Serum estrone, estradiol, estriol, progesterone, 17 alpha-hydroxyprogesterone, and testosterone were determined in the sera of 25 normal males and 25 patients with obstructive azoospermia. An increase in testosterone and estriol levels, and a decrease in other hormones were demonstrated in patients with obstructive azoospermia. These long-term effects of obstruction of the vas apparently also occur in comparable situations, for example, after vasectomy.
