Background and Aim: On the background of claims that ulipristal acetate is the most effective hormonal medication for emergency contraception, the critical analysis investigates the pharmacological, medical, legal, and ethical aspects of this medication. The aim is to illuminate critical issues not yet sufficiently explored in research on emergency contraception.

Method and Material: The method is a critical analysis which assesses present knowledge contained in pertinent high-quality publications. The material encompasses articles published in high-ranked scientific journals and information disseminated by the most influential health agencies, such as the US Food and Drug Administration, the World Health Organization, the American College of Obstetricians and Gynecologists, and the American College of Pediatricians.

Results: The analysis of pharmacological aspects of ulipristal acetate shows that its similarity to mifepristone raises the question regarding abortifacient potentials of ulipristal acetate. The analysis of medical aspects of ulipristal acetate reveals that adverse events are not sufficiently described and that statistical methods for determining efficacy need to be refined. The analysis of legal aspects suggests that legislation on abortion medication might be relevant not only for mifepristone but also for ulipristal acetate. The analysis of ethical aspects unveils that the physiological processes of fertilization and implantation are crucial in discussions on the beginning of human life.

Conclusions and Implications: Concerning pharmacology it seems advisable to continue research on the mechanism of action of ulipristal acetate not only as a contraceptive but also as a contragestive. Concerning medical research, the efficacy of ulipristal acetate as a preventive therapy should be investigated with increased statistical verifiability. The results of these investigations should be communicated comprehensibly to the patient. Concerning legal aspects, the suitability of ulipristal acetate as abortion medication should be discussed on the basis of findings in human physiology. Concerning ethical debates the question of the beginning of life should be based on scientific insights into the physiological processes of ovulation, fertilization, and implantation.
