윤활제는 일반적으로 질건조증으로 인한 성교의 어려움을 돕기 위한 '러브젤'로 사용되지만 인공 수정 병원에서도 원활한 인공수정 과정을 위해 윤활제를 쓰기도 한다.

상임 연구원인 카짐 초한은 윤활제가 임신에 방해가 될 수 있다고 밝혔다.

뉴욕주립대학교에서 진행된 연구는 건강한 남성 22명에게서 받은 정자를 5개의 윤활제와 4개의 미네랄 오일에 1시간 동안 노출시킨 후의 반응을 관찰한 것이다.

윤활제 '프리시드'를 제외한 나머지 존슨앤존슨 제품 3개의 윤활제와 국내에서 유명한 아스트로 글로이드는 정자의 활동을 저하한다는 결과가 나왔다고 로이터헬스는 전했다.

실험 대상이었던 미네랄 오일중 카놀라유와 베이비오일은 정자 활동에 영향을 미치지 않지만 참기름에 노출됐던 정자는 낮은 활동량을 기록했다. 반면, 겨자씨 기름에 노출됐던 정자는 활동량이 상당량 증가 했으며 이 상태가 한 시간 이상 지속됐다고 발표했다.

연구진들은 임신을 원할 경우 시중에 판매되는 윤활제 대신 미네랄 오일을 쓸 것을 권고했다.

Sexual lubricants hinder conception: study

A study reported by Reuters Health discovered decreased movement in sperm when exposed to commercial gels.

Commercial gels are commonly used by couples to overcome vaginal dryness during intercourse. At fertility clinics, gels are offered to men during semen collection and applied to medical devices to make them easier to insert into the body.

However, Kazim R. Chohan, senior author of the study and director of the Andrology Laboratory at the State University of New York Upstate Medical Center in Syracuse suggested that these lubricants are not beneficial for couples who wish to conceive, according to the repot.

The researchers analyzed the movement of sperm from 22 healthy donors in separate test tubes with five commercial gels and four common oils. The semen was exposed to each product for an hour, it said.

The commercial lubricant products tested were Pre-Seed, Johnson & Johnson’s K-Y Tingling Jelly, K-Y Sensitive Jelly, K-Y Warming Jelly and Astroglide. The four common oils tested were mineral oils available as lubricants: canola oil, baby oil, sesame oil and mustard oil.

The results presented were surprising. All the commercial lubricants except Pre-Seed, a product specially formulated to help with conception, diminished the activity of sperm. Canola or baby oil had no negative impact on sperm while sesame oil drastically affected sperm movement.

Mustard oil showed the most astounding result. The semen mixed into a tube of mustard oil became hyperactive and stayed that way for at least an hour. Mustard oil was tested as it is known to kill bacteria -- hence it is often used as a vaginal lubricant by sex workers in Bangladesh, Reuters reported.
