Mechanism of action
COCs prevent fertilization and, therefore, qualify as contraceptives. There is no significant evidence that they work after fertilization. The progestins in all COCs provide most of the contraceptive effect by suppressing ovulation and thickening cervical mucus, although the estrogens also make a small contribution to ovulation suppression. Cycle control is enhanced by the estrogen.
Because COCs so effectively suppress ovulation and block ascent of sperm into the upper genital tract, the potential impact on endometrial receptivity to implantation is almost academic. When the two primary mechanisms fail, the fact that pregnancy occurs despite the endometrial changes demonstrates that those endometrial changes do not significantly contribute to the pill's mechanism of action.
Promoters have used in-ring accidents that led to injuries, or in extreme cases death, as a way to make a heel even more hated and unpopular. In 1971 Alberto Torres died three days after wrestling Ox Baker . Evidence indicated that Torres died of a ruptured appendix , Baker's Heart punch finishing move was the kayfabe reason; the death was worked into Baker's wrestling persona by the promoters making Baker the most hated heel in the territory at the time.  Acts exploiting personal tragedy or death became less and less prevalent by the turn of the century with fans being more aware of the worked nature of professional wrestling.
