Effect of mifepristone on inhibition of ovulation and induction of luteolysis

Human Reproduction, 1994
Mifepristone administration to women in the mid- or late follicular phase delays the luteinizing hormone (LH) surge and prolongs the follicular phase. Since the resumption of follicular growth commences following mifepristone cessation, the drug must be given either continuously or at repeated intervals in order to block ovulation.

Perforin Expression in Human Cell-Mediated Luteolysis

International Journal of Gynecological Pathology, 1995
After ovulation and in the absence of fertilization, the human corpus luteum regresses in an orderly sequence of morphological changes. This study demonstrated that luteal regression involved progressive infiltration of lymphocytes and macrophages.

Effect of indomethacin on estrogen-induced luteolysis in the ewe

Prostaglandins, 1977
Three groups of 6 ewes were laparotomized on day 9 of an estrous cycle (estrus = day 0) and the corporà lutea (CL) were marked with India ink. Indwelling cannulae were inserted into the uterine horn adjacent to the CL in groups 2 and 3. Group 1 was injected intramuscularly (i.m.) with corn oil twice daily on day 9.

Luteolysis as Affected by Uterine Transplantation in the Syrian Hamster

Endocrinology, 1967
Total hysterectomy in the hamster prolonged corpora luteal life span as measured by the length of copulation-induced pseudopregnancy (18.10 days as opposed to 9.20 days). Reversal of this elongation was accomplished by homologous uterine transplantation to the cheek pouch.

Calcium: A Cellular Mediator of Luteolysis

1984
Regression of the corpus luteum with the consequent loss of ovarian progesterone secretion appears to be an induced response which is necessary for the re-occurrence of ovulation. Conversely, prevention of corpus luteum regression is essential for the continuation of pregnancy.

A 40-year odyssey into the mysteries of equine luteolysis

Theriogenology, 2009
Variation is the principal barrier to progress in unraveling the complexities of biological mechanisms. The resulting slow research progress is well illustrated in the chronology of events in elucidating the mechanism for regression of the corpus luteum (luteolysis) during the equine estrous cycle.

Enclomiphene induces luteolysis in the nonpregnant guinea pig

Experientia, 1989
The effect of two antiestrogens, enclomiphene and tamoxifen, on luteal function in the guinea pig was compared to that of estradiol, a known luteolysin. Enclomiphene caused premature luteolysis when administered during the early or mid-luteal phase of the cycle, but was not as potent as estradiol. Tamoxifen had no effect.
