Pregnancy loss during the normal lifespan of endometrial cups (~37-120-150 days of gestation) may affect a mare's ability to conceive again in the same breeding season, as equine chorionic gonadotropin (eCG) secretion by retained endometrial cups can lead to abnormal ovulations and follicular...

The first pregnancy was aborted at Day 75 after ovulation in conjunction...

Abstract

When an anoestrus mare is presented, gestation must be excluded. The status of the ovaries may aid in the diagnosis of different causes of anoestrus as indicated in the preceding article such as lack of follicular growth, persistent luteal tissue, or ovarian cycling. The first indication of lack of ...

Early pregnancy failure in mares may be due to three conditions: spontaneous retention of the corpus luteum, embryonal death after the recognition of pregnancy and embryonal death after the formation of endometrial cups. These conditions cause temporary infertility in mares. The mechanisms...

Abstract

Five mature American Quarter Horse mares were bled every 30 min for 25 h, beginning at 09.00 h on day 50 of pregnancy, to determine the short-term mode of secretion of equine chorionic gonadotropin (eCG). Three mares with persistent endometrial cups after abortion were injected with 1.0 mu g...
