Lobster Ingredient Offers Hope for a Highly Effective Contraceptive!

A new non-hormonal birth control method prevents 98% of the estimated 100 million sperm released during ejaculation from entering the cervix, and the key ingredient here comes from lobsters.

Scientists at the Karolinska Institute in Sweden have developed the gel using tiny fibrous compounds called chitosan, which are found in the exoskeletons of marine organisms, shrimp and crabs.

Once applied, the gel works for hours to strengthen the cervical mucosal barrier and prevent pregnancy without the side effects of traditional birth control methods that are 91 to 99 percent effective.

And unlike existing contraceptives, the team said their innovation does not cause the unwanted side effects that sometimes prevent women from using such treatments.

“Gels like this can be used in seconds,” said Thomas Crozier, a biomaterials engineer at the KTH Royal Institute of Technology in Sweden and co-author of the new study. “Let’s imagine that such a product should be usable. from a few seconds to several hours before intercourse. The effect can last for hours, but weakens over time as the natural replacement of the mucous barrier.

The team explained that when tested on sheep alone, chitosan was shown to have a similar effect in laboratory tests using cervical mucus and human semen.

Hormonal contraceptives, including implants, pills, injections, and skin patches, are made up of estrogen and progesterone.

The hormone progesterone prevents the contraction of the muscles of the uterus, which leads to the fact that the woman’s body rejects the egg.
However, these hormones cause headaches, diarrhea, and even bone pain.

KTH replaces the hormone chitosan, a sugar found in the outer skeleton that reduces the fat and cholesterol that the body absorbs from food.

It also aids blood clotting when applied to wounds.

A new non-hormonal contraceptive gel combines a mucoprotein called mucin and chitosan to temporarily thicken cervical mucus, making it difficult for sperm to pass.

Crozier said the mechanism uses the natural capacity of cervical mucus as a barrier that insulates the vagina, where bacteria thrive, from the uterus and upper genital tract.

Cervical mucus also regulates the movement of sperm.

In the run-up to ovulation, the mucosal barrier becomes a more selective gatekeeper, making exceptions for the selection of spermatozoa in the uterus.

Chitosan molecules are mucoadhesives, that is, they interact with the mucous gel in the cervical canal. Interacting with the gel of cervical mucus, chitosan seals the pores of the gel and makes it impossible for sperm to penetrate.
