Question

Which form of birth control could people use without altering hormonal systems or blocking sperm from fertilizing an egg?

Answer 1

It depends on the size and the thickness of the pill

Step-by-step explanation:

A hormonal IUD or IUS releases a progestin hormone (levonorgestrel) into the uterus. The released hormone causes thickening of the cervical mucus, inhibits sperm from reaching or fertilizing the egg, thins the uterine lining, and may prevent the ovaries from releasing eggs.
