Is Lube Safe for Pregnancy? Or Can Lubricants Reduce the Chance of Me Getting Pregnant?

Explore the safety of using lubricants during conception. Discover which types are sperm-friendly and how some products might affect fertility.

Couples navigating the journey of conception often turn to lubricants to address vaginal dryness, a common concern among women of childbearing age. The impetus behind this issue can vary, with some associating intercourse more with achieving a specific outcome rather than seeking pleasure.

But, naturally, many couples ask the question: Is lube safe for pregnancy?

Is lube safe for pregnancy and trying to conceive?

Multiple studies have shown that some commercial lubricants such as KY Jelly and Astroglide as well as saliva, are toxic to sperm. When such products are mixed with semen, they can reduce the mobility of Sperm in vitro.(1)(2)(3)(4)

Anderson Et al suggested that the decrease in mobility is likely to be due to the contrasting pH of the lubricant (<5) versus the optimum pH of sperm (7.2-8.5). Their findings have also guided clinicians to recommend light oils or higher pH lubricants among couples trying to conceive, as they seemed to cause a slightly less detrimental effect.

However, does this imply an outright cessation of lubricant use for those aspiring to conceive, or a shift toward oils if assistance is deemed necessary?


Life, fortunately, presents a more nuanced reality than the confines of a controlled laboratory setting. Numerous factors influence one's likelihood of conception beyond simply the choice of lubricant.

Indeed, studies have emerged suggesting that lubricant use may not significantly impact the chances of conception.

Steiner et al. delved into the matter by examining nearly 300 couples striving to conceive, discovering that despite in vitro findings suggesting caution regarding lubricant use during conception, lubricants did not hinder their chances whatsoever.

They theorised that real-world exposure to lubricants might differ significantly from the controlled conditions of in vitro testing.

Additionally, they posited that lubricant use could potentially foster increased sexual frequency, thereby enhancing the prospects of conception.(5)

A broader, transcontinental study conducted by McInerney et al. explored various types of lubricants—water-based, fertility-safe, silicone-based, and oil-based—utilised during conception.

Interestingly, they found that among these options, oil-based lubricants exhibited a slight edge in aiding conception. (6)

For couples earnestly seeking to optimise their chances of conception, the incorporation of an oil-based lubricant may be considered. However, it's crucial to temper expectations, as the purported increase in effectiveness remains marginal.

What lubricants to watch out for if you’re trying to conceive.

As long as you are steering clear from lubes with spermicidal actives (look out for nonxynol-9) the likelihood of lubricants affecting your chance to conceive is marginal.

But if you really want to be sure, oil lubricants are the way to go.
