Why Oral Contraceptives are Still the Method of Choice
Oral contraceptives are highly effective in preventing pregnancy when taken consistently and correctly, boasting a success rate of over 99%. These contraceptives typically combine synthetic forms of estrogen and progestin, which work synergistically to inhibit ovulation by suppressing the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland. Additionally, oral contraceptives thicken cervical mucus, creating a barrier to sperm entry, and alter the endometrial lining, making it less receptive to a fertilized egg.
