Sterilin - a drug with a local contraceptive effect.The active component of Steriline nonoxynol-9 has a pronounced destructive effect against spermatozoa. Nonoxynol-9 in chemical composition is a non-ionic surfactant containing a quaternary Nitrogen atom. It lyses the membrane of the sperm acrosome, which leads to its fragmentation and loss of mobility. As a result, the sperm loses its ability to dissolve the oocyte membrane.

 

Sterilin has a bactericidal and fungicidal action against pathogens of urinary infections (chlamydia, gonococci). In vitro, virucidal activity against HIV (human immunodeficiency virus) has been identified, but there is no clinical confirmation of a reduction in the risk of HIV infection with nonoxynol.

 

The drug does not contain hormones, does not enter the systemic bloodstream, does not irritate the mucous membrane and skin, does not have an unpleasant odor, has a lubricating effect. When using Sterilin, foam does not form.

Response of a gynecologist

 

In practice, spermicides show their insufficient reliability when used as the main method of contraception. There are enough cases of unwanted pregnancy against unprotected sex acts using Sterilin.Spermicides, including this drug, are more suitable for insurance in parallel with the intake of hormonal contraceptives, the use of condoms or, in extreme cases, interrupted intercourse, if other methods are not possible because of contraindications (varicose, allergy to latex). Another disadvantage of candles is a large percentage of side effects in the form of burning and irritation.
