How does phexxi prevent pregnancy?

How does Phexxi work to prevent pregnancy?

Phexxi (lactic acid, citric acid, and potassium bitartrate) prevents pregnancy by changing the vaginal environment so sperm can’t move or survive as well. It works by shifting vaginal fluid to be more acidic and less favorable for sperm around the time of sex [1].

What happens to sperm after Phexxi is used?

Sperm are sensitive to the pH and overall conditions in the vagina. By lowering vaginal pH, Phexxi makes it harder for sperm to remain functional and to reach an egg [1].

Is Phexxi an emergency contraceptive?

Phexxi is used as a contraception method around the time of sex (before intercourse), not as an emergency treatment after sex has already occurred [1].

How does it differ from hormonal birth control?

Phexxi does not work by stopping ovulation or changing hormone levels. Instead, it prevents pregnancy by altering the vaginal environment to inhibit sperm survival and movement [1].
