A two-year follow-up study of progestogen-only contraception with chlormadinone acetate indicates no increase of the level of factors VII and X, as found after three cycles with all oestrogen-progestogen oral contraceptives. Clotting factors which were raised with combined preparations became normal after the sixth monthly cycle of progestogen and remained normal during the two-year period of s...

The effects on clotting tests and platelet function of six months' continuous administration of the 19-norsteroid, progestogen-only contraceptive, norethisterone, have been studied in four groups of women. In a group of women who have not previously taken oral contraceptive no acceleration of clotting or platelet factors was found, but in contrast a tendency to reduced coagulability was observe...

Two commercially available progestogen products for cattle, melengestrol acetate (MGA) and norgestomet (SMB), were evaluated for their ability to induce synchronized estrus in anovulatory ewes. Seasonally anestrous ewes (n = 232) were randomly assigned to one of seven treatments: 1) control (C); 2) MGA only (OMGA; .3 mg of MGA/d); 3) MGA+zeranol (RMGA; 2.5 mg of zeranol); 4) MGA+PG-600 (PMGA; 4...

Oral contraceptives containing only a progestogen have had a chequered career. In 1965 trials in Latin America showed that very small amounts of a progestogen, chlormadinone acetate, when given without any added oestrogen had a strong antifertility effect. Not all progestogens are suitable for use alone. Indeed with norethynodrel, the progestogen most commonly used in the late 1960s, the amount...

Two-hundred-fifty-six crossbred and Targhee ewes which lambed in February and March were randomly assigned to a 38or 73-day postpartum weaning group and within weaning group to a control, an 8or a 16-day progestogen treatment. Treatment was an intravaginal progestogen pessary for 7 days after weaning or for 15 days beginning 8 days before weaning with a 10 mg injection of progesterone on the da...

1. The value of progestogen therapy in the prevention of postmenopausal bone loss was assessed in 30 women, by a preliminary randomized controlled trial of gestronol or mestranol, in comparison with a placebo. 2. When the skeletal response was measured by photon absorptiometry, bone mineral loss was prevented by both the oestrogen and the progestogen. 3. We confirm that mestranol significantly ...

OBJECTIVE To evaluate the breast histomorphometric changes in rats treated with estrogen and/or progestogen for a short period of time. METHODS Forty oophorectomized rats were divided into four groups: GC, vehicle; GE, treated with estradiol benzoate (37.6 mg/animal); GP, treated with medroxyprogesterone acetate (11.2 mg/animal) and GEP, treated with estradiol benzoate (37.6 mg/animal) plus m...

Vacuum curettage was performed on 348 women who had received various regimens of oestrogen treatment for an average of 9.7 months for climacteric symptoms. In 62 cases (18%) the specimens were unsatisfactory for histological assessment; among the remainder, however, they showed a normal endometrium in 257 cases (90%), cystic hyperplasia in 21 (7%), adenomatous hyperplasia in 7 (2%), and endomet...

Premenstrual depression, postnatal depression and climacteric depression are related to changes in ovarian hormone levels and can be effectively treated by hormones. It is unfortunate that psychiatrists have not accepted this form of treatment and this paper is an attempt to simplify this treatment, which should include transdermal estrogens, possibly testosterone and, if the woman has a uterus...
