Saheli pills, also known as centchroman, are a non-hormonal contraceptive pill primarily used by women in India. There are several reasons why some women choose to use Saheli pills:

1. Non-hormonal: Saheli pills do not contain hormones like estrogen or progesterone, unlike many other contraceptive methods such as birth control pills or hormonal IUDs. Some women may prefer non-hormonal methods due to concerns about hormonal side effects or health risks associated with hormonal contraceptives.

2. Fewer side effects: Saheli pills are generally well-tolerated and have fewer side effects compared to hormonal contraceptives. This can be appealing to women who have experienced side effects with other contraceptive methods or who are looking for a more natural option.

3. Reversible: Saheli pills are reversible, meaning that fertility returns shortly after discontinuing use. This makes them suitable for women who may want to become pregnant in the future or who are looking for a temporary contraceptive option.

4. Long-acting: Saheli pills are taken once a week, making them a convenient option for women who may have difficulty remembering to take a daily pill or who prefer not to use more invasive contraceptive methods like implants or IUDs.

5. Cultural preferences: In some cultures, there may be preferences for non-hormonal contraceptive methods, and Saheli pills provide an option that aligns with these preferences.

Overall, Saheli pills offer women a non-hormonal, reversible, and relatively side-effect-free contraceptive option, making them a popular choice for some women, particularly in regions like India where they are widely available.
