Final answer:
A triphasic pill is the type of oral contraceptive with three different doses of hormones in the active pills, designed to mimic natural hormone fluctuations.
Step-by-step explanation:
A type of oral contraceptive that contains three different doses of hormones in the active pills is called a C) Triphasic pill. These pills have varying hormone levels designed to mimic the natural fluctuations in your hormone levels throughout your menstrual cycle.
Oral contraceptives are hormonal methods of birth control and are among the most common forms of hormonal contraception. They work by interfering with ovulation, fertilization, and/or implantation of the fertilized egg. The combined pill, which includes both estrogen and progesterone, is taken daily to ensure that the ovaries do not release an egg. Moreover, the pill induces changes in the uterine lining and cervical mucus to prevent sperm from reaching the egg. Triphasic pills are an advanced form of these combined pills.
