[Self concept patterns according to the Tennessee self concept scale in vasectomized men and their partners]. / Patrones de autoconcepto según la escala Tennessee en hombres vasectomizados y sus parejas.

PIP: This study investigates 40 couples whose male partners had voluntarily undergone vasectomy as a permanent contraceptive method. The Tennessee self concept scale test was used to examine changes, if any, in personality characteristics. The only changes were in self-perception of conflict and identity, while adjustment-disadjustment patterns, and psychosis and neurosis patterns remained identical to those tested before vasectomy. The typical negative characteristics of Mexican men and women, i.e., confusion regarding self-perception, passivity, dependence, social insecurity, and the positive ones, such as ability to socially communicate, and emotional perception, were not changed, as was unchanged the conflict as to sexual identity which often prevents Mexicans to fully enjoy sexual gratification. Changes in intellectual capacity were measured, before and after vasectomy, with the Beta test. Both men and women showed an increased capacity in intellectual performance.^ieng

Presence of corpus luteum as evidence of ovulation in women treated with low doses of chlormadinone acetate.

PIP: 50 women under continuous treatment for 1-31 months with 500 mcg chlormadinone acetate daily were studied. Culdoscopy was performed between Day 14 and 23 of their menstrual cycles. A corpus luteum was thought to be observed in 37 cases. In 18 with suspected corpus luteum a wedge resection of the ovary was done. Examination of patients 10 days after operation revealed no complications. In 4 cases subsequent culdoscopic examinations revealed no traces of biopsy damage. In 5 an endometrial biopsy was obtained the same day as the ovarian one or shortly thereafter. The 18 ovarian biopsies showed recent corpora lutea in 12, old corpus luteum in 1, follicular and theca-lutein cysts in 2, and normal follicles without corpus luteum in 3. Endometrial biopsies revealed 2 instances of normal secretory endometrium and 1 case of irregular endometrium with corpora lutea. Evidence of ovulation occurred in 70%. The reported pregnancy rate with low-dose progestogen therapy has been 3.7/100 years of woman exposure. The exact mechanism of contraception by chlormadinone acetate has not been determined.^ieng
