Six things to know about how heat stress compromises fertility of the cow (and probably other mammals as well).

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Review of the primary literature was used to develop six propositions regarding the nature of actions of heat stress on fertility of the bovine female. The first two propositions are that the reduction in fertility caused by heat stress is due to 1) negative effects on the competence of the oocyte to be fertilized and 2) support embryonic development and death of the embryo when exposed to elevated temperature. The third proposition is that it remains unclear whether damage to the spermatozoa occurs after deposition in the reproductive tract of a heat-stressed female. Fourth, the embryo acquires resistance to heat stress after activation of the embryonic genome. Fifth, heat stress after the first few days of pregnancy usually has only slight effects on embryonic or fetal survival. Sixth, the magnitude of effects of heat stress on fertility is related to the degree of hyperthermia experienced by the female. Thus, physiological and environmental factors that control ability of an animal to regulate its body temperature during heat stress are important determinants of the magnitude of the impact of heat stress on fertility.
