Researchers Find Lubricant Doesn't Hinder Fertility

May 7 -- TUESDAY, May 6 (HealthDay News) -- Couples trying to conceive should choose the lubricant they use wisely because some lubricants can affect sperm motility, a new study finds.

"Most commercial lubricants are toxic to sperm, and couples who want fertility should think about carefully choosing the lubricant they want," said study author Dr. William H. Kutteh, a reproductive endocrinologist at the University of Tennessee, in Memphis.

For the study, Kutteh and his team tested four commercially available lubricants against a new "fertility-friendly" lubricant developed by the researchers.

Their lubricant, called ConceivEase, didn't adversely affect sperm motility, Kutteh said, although the other four lubricants did. The new lubricant, with a patent pending, is made by Reproductive Laboratory Inc. in Memphis. Kutteh is an owner of the company and the product is distributed by Sepal Reproductive Devices in Boston, he said.

Kutteh was to present the findings Monday at the American College of Obstetricians and Gynecologists annual meeting, in New Orleans.

The test results could be good news for couples having difficulty conceiving, he said. "People are afraid of going to a fertility doctor because they think they will have to spend $10,000 on IVF [in vitro fertilization]," he said. "Sometimes all you need is a $14.99 oil change."

If sperm aren't moving properly, fertility is affected, Kutteh said. "The sperm have to move through the vagina, through the cervical mucus and out to the fallopian tube. Anything that decreases the motility of the sperm will make the pregnancy rate decline. Sperm can live for 48 to 72 hours."

For the study, five men who had initial sperm counts above 65 percent motility donated sperm. Kutteh's team then exposed the sperm to four commercially available lubricants -- K-Y Jelly, Replens, Touch and Astroglide, along with ConceivEase.

The effects on sperm motility were evaluated at 1 minute, 15 minutes, 30 minutes and one hour. While the ConceivEase maintained sperm motility at 65 percent, the others did not. At one hour, the motility of the sperm exposed to Touch was down to 10 percent, while sperm exposed to the other three lubricants was down to zero, the study found.
