The level of the androgenic effect refers to the chance of unwanted side effects such as acne and hirsutism (female unwanted hair growth), which increase as the androgenic level increases.

This progestin also has medium progestational activity. The level of progestational effects refers to how successful the progestin is at preventing ovulation and lessening menstrual bleeding – the higher the better. This progestin is a mid-level ovulation inhibitor.
