Ovral is a combined oral contraceptive medication containing ethinyl estradiol and levonorgestrel. It is used primarily to prevent pregnancy by inhibiting ovulation. The medication works by delivering synthetic hormones that mimic the natural estrogen and progestin cycles. This hormonal mimicry suppresses the release of gonadotropin-releasing hormone, preventing follicular development. The progestin component also thickens cervical mucus, creating a barrier to sperm penetration. Together these actions alter the endometrium and fallopian tube environment, reducing the likelihood of fertilization and implantation.

Ovral is a combined oral contraceptive medication containing ethinyl estradiol and levonorgestrel. It works by suppressing the hypothalamic-pituitary axis to prevent ovulation. The progestin component thickens cervical mucus, reducing sperm penetration and altering endometrial receptivity. Together these actions provide high contraceptive efficacy when taken as prescribed. Pharmacologically the ethinyl estradiol component provides estrogenic activity, while levonorgestrel delivers potent progestogenic effects. This combination leads to stable hormone levels that maintain suppression of follicular development and alteration of the uterine lining. Clinically these properties translate into a reliable birth-control option with predictable bleeding patterns and reduced risk of unintended pregnancy.

Ovral may cause nausea or occasional vomiting in some users. Headaches and breast tenderness are reported side effects. Spotting between periods can occur. Some individuals experience mood changes or mild depression. Weight fluctuations are occasionally noted. Rarely users may develop acne or changes in skin oiliness.
