In a study of the effects of estrogen administration (usually subcutaneous implantation between the shoulder blades) upon the guinea pig corpus luteum (CL) diethyl stilbestrol estradiol estradiol propionate and estradiol cypionate were administered in various experiments. Estrogen (50 mcg-75 mg) administered before Cycle Day 5 caused premature regression of the CL. After hysterectomy or hemihysterectomy no luteolytic effect occurred in the ovary on the side of the horn which had been removed…

Luteal expression of factors involved in the metabolism and sensitivity to estrogens in the dog during pregnancy and in non-pregnant cycle.

The results suggest that E2 signalling and biologically active local concentrations could diverge in response to time and pregnancy status of the bitch.

Effects of daily administration of estradiol-17 beta on follicular growth, ovulation, and plasma hormones in mares.

Mares in the control group of this study exhibited a bimodal pattern of FSH secretion, while treatment of mares with E2 altered the pattern ofFSH secretion by suppressing FSH concentrations during early diestrus.

Comparison of luteinized unruptured follicles and corpora lutea: steroid hormone production and response to luteolytic and luteotropic agents.

It is concluded that the attenuated luteal-phase P profile following induction of LUFs is not an intrinsic deficiency in hormone production, but may arise from the smaller mass of lutenal tissue and from earlier than normal development of responsiveness to the luteolytic effects of PGF.

Effect of oestrogen on pregnancy of guinea-pigs.

Pregnant guinea-pigs were injected with oestrogen at different stages of gestation and the maternal progesterone concentrations were lower than in control animals and Histology showed deleterious changes in the corpora lutea.

Follicular growth and estradiol influence on luteal function in mares.

Results suggest that diestrus follicular growth and its consequent estradiol production may play a role in initiating luteolysis through endometrial PGF2 alpha production and that delay or failure of this process may result in spontaneously prolonged corpora luteal function.

Mode of action of oestrogen in maintaining the functional life of corpora lutea in sheep.

It was con-cluded that oestrogen is luteotrophic principally because of its action on the uterus, where it seems to interfere with the normal luteolytic mechanism.

Luteolytic effect of oestrogen on the corpora lutea of the cyclic guinea-pig.

The effect of a single sc injection of 10 or 50 mcg estradiol cyclopentylpropionate on the corpora lutea (CL) of cyclic guinea pigs was studied and luteolysis was induced by ECP when injected on Days 1 or 4 of the cycle but not Day 6.

Reversal by gonadotrophins of the luteolytic effect of oestrogen in the cyclic guinea-pig.

The results indicate that oestrogen induces luteal regression in the cyclic guinea-pig by inhibiting the pituitary secretion of fsh which is apparently necessary for the normal maintenance of corpora lutea.

The corpora lutea that formed post-operatively responded in the same way as those in animals operated on the 5th or 10th days of the luteal phase, and the nature of the stimulus of hysterectomy on the corpus luteum of the guinea-pig is discussed briefly.

Corpus luteum function in the guinea-pig; arterial and luteal progesterone levels, and the effects of hysterectomy and hypophysectomy.

In intact guinea-pigs the concentration of progesterone in luteal tissue rose and fell in a pattern similar to that of the volume of the corpus luteum, which in pregnancy grew to nearly twice the

Luteotropic complex of the hamster.

Treatment with prolactin and FSH increased the vascularity of the CL and maintained pregnancy in the majority of animals; hence, the concerted interaction of these 2 hormones constituted the minimal luteotropic complex (LtH) of the hamster.

The effect of hypophysial stalk-section on the corpus luteum of the guinea-pig.

It is indicated that prolactin can have substantial luteotrophic activity in the guinea-pig and that stalk-section did not prevent luteal regression at the normal time.

Luteolytic Effect of Prostaglandin in the Guinea-pig

The local nature of the effect of the uterus on the corpus luteum in the guinea-pig seems to indicate that the pituitary is not directly involved, but efforts to extract an endometrial luteolytic substance have been unsuccessful in this species.

Gonadal Hormones and the Regression of the Corpora Lutea in the Guinea-pig

The results of the following experiments involving the administration of oestrogen or progesterone indicate that the inhibitory effect of gonadal hormones on luteal function is exerted through the uterus and lends further support to the view that the uterus exercises a controlling influence on lutenal function in the guinea-pig.

Changes in the metabolic clearance rate of progesterone in the guinea-pig.

The metabolic clearing rate (MCR) of progesterone in guinea pigs was studied using the continuous infusion of tritiated progesterONE and the decrease seems to depend on the presence of a viable conceptus.
