What is a Yoni Egg?
Yoni Egg: A yoni egg is a smooth, egg shaped stone such as jade, quartz, or obsidian worn inside the vagina, marketed for pelvic floor and wellness benefits that are not supported by medical evidence and that carry real hygiene and pelvic floor risks.
Also known as: jade egg, crystal egg, vaginal egg, kegel egg, yoni stone.
A yoni egg is a polished gemstone carved into an egg shape and sold to be worn internally, usually with a wellness story attached: stronger pelvic floor, better orgasms, balanced hormones, feminine energy. Yoni is a Sanskrit word for womb or source, and the eggs are often described as an ancient Chinese practice. This entry exists because people search for the term, and because the honest answer is that the claims do not hold up and medical bodies advise against using them.
If pelvic floor strength or sensation is what you are after, there are well tested tools that do that job without the drawbacks, chiefly body safe silicone kegel balls used with a proper contract and release routine. The rest of this entry explains what yoni eggs are, why doctors caution against them, and what to reach for instead.
What Is a Yoni Egg
Yoni eggs are typically carved from jade, rose quartz, or black obsidian and come in a few sizes. Some are drilled through one end so a string can be threaded for removal; others are solid. The instructions that come with them usually involve inserting the egg and holding it in place with the vaginal muscles for a period of time, sometimes while walking around or meditating.
The origin story is part of the marketing. Despite claims of centuries of use by Chinese royalty, a review published in a peer reviewed journal found no historical evidence that jade eggs were used vaginally for any purpose in ancient China. The modern popularity of yoni eggs comes from celebrity wellness brands and social media rather than tradition.
Types of Yoni Egg
Yoni eggs are sorted by stone and by whether they are drilled, and every type shares the same underlying issues.
- Jade egg: The stone most associated with the trend; semi porous, so bacteria can lodge in the surface and resist cleaning.
- Rose quartz egg: Chosen for its colour; also a semi porous crystal with the same hygiene concern.
- Black obsidian egg: Volcanic glass that is less porous but can chip or crack, leaving sharp edges inside the body.
- Drilled egg: Has a hole for a removal string, which makes retrieval easier but adds a crevice that is hard to clean.
- Undrilled egg: Solid with no string, so removal relies entirely on bearing down, and the smooth stone can be difficult to grip.
Why Doctors Advise Against Yoni Eggs
The first problem is the pelvic floor itself. Holding an egg in place means clenching continuously, which is the opposite of what pelvic floor training does. Proper training is a sequence of contracting, releasing, and relaxing, and sustained clenching can lead to tension and painful muscle spasms rather than strength. A tool that is sold for the pelvic floor can work against it.
The second is hygiene. Gemstones look solid but jade and quartz are semi porous, with tiny gaps where fluids and bacteria can settle and stay even after washing. Stones can also chip or crack, and rough spots inside the vagina can cause scratches or tears that invite infection. Keeping any object in the vagina for an extended time raises the risk of toxic shock syndrome, and a smooth, slippery egg can be hard to retrieve.
The third is that the benefits are unproven. There is no clinical evidence that a stone egg strengthens muscles, regulates cycles, eases cramps, or improves libido. Anyone with pelvic floor symptoms such as leaking, heaviness, or pain should see a doctor or pelvic floor physiotherapist rather than an egg, since doing pelvic exercises incorrectly can make existing problems worse.
What to Use Instead
For pelvic floor work, the evidence supports Kegel exercises done correctly, ideally learned from a pelvic floor physiotherapist if you have any symptoms. Weighted silicone kegel balls or ben wa balls are the mainstream tool for that: they are non porous, easy to sterilise, sized for the job, and come with a retrieval cord. Used for short sessions with a contract and release routine, they add resistance without asking you to clench for an hour.
For sensation or sexual pleasure, a body safe silicone or glass toy designed for internal use does what a yoni egg is claimed to do without the porous surface or the retrieval problem. And for hormonal, menstrual, or libido concerns, the useful step is a conversation with a healthcare provider, since those issues have real causes and real treatments.
Yoni Egg vs Kegel Balls: Quick Comparison
| Yoni Egg | Kegel Balls | |
|---|---|---|
| Material | Semi porous gemstone or brittle volcanic glass | Non porous body safe silicone, sometimes with a metal core |
| Cleaning | Difficult to fully sanitise | Soap and water or boiling, easy to sterilise |
| How it is used | Held in by continuous clenching | Short sessions with a contract and release routine |
| Removal | String if drilled, otherwise bearing down; can get stuck | Built in retrieval cord |
| Evidence | No clinical support for any claimed benefit | Pelvic floor training is well studied; balls add resistance to it |
| Medical view | Advised against | Generally fine with correct technique; see a physio if symptomatic |

Talking to a Partner or Provider About It
If a partner or a friend is enthusiastic about yoni eggs, the useful conversation is about the goal rather than the object. Pelvic floor strength, better orgasms, and feeling connected to your body are all reasonable aims, and each has a safer route. If you have already used a yoni egg and notice unusual discharge, pain, fever, or pelvic tension, mention it to a doctor. It is a common question and nothing to be embarrassed about.

Key Things to Know
- Yoni eggs have no proven benefits; the pelvic floor, hormonal, and sexual claims are not supported by clinical evidence.
- Holding an egg in place means clenching continuously, which skips the contract, release, and relax sequence real pelvic floor training needs and can cause painful spasms.
- Jade and quartz are semi porous, so bacteria can lodge in the stone and survive cleaning, and any stone can chip and scratch internal tissue.
- Keeping any object in the vagina for an extended time raises the risk of toxic shock syndrome, and a smooth egg can be hard to remove.
- The ancient Chinese origin story is marketing; published research found no historical evidence for it.
- Silicone kegel balls with a retrieval cord, used for short contract and release sessions, are the evidence based alternative, and a pelvic floor physiotherapist is the right person for any symptoms.
FAQ
Are yoni eggs safe to use?
Medical professionals generally advise against them. Gemstones are semi porous and hard to fully clean, they can chip and scratch internal tissue, keeping one in for a long time raises the risk of toxic shock syndrome, and the continuous clenching needed to hold it can cause pelvic floor spasms. Body safe silicone kegel balls are the safer option for the same goals.
Do yoni eggs strengthen the pelvic floor?
No. Pelvic floor training relies on contracting, releasing, and relaxing the muscles. Holding an egg in place is sustained clenching, which does not train the muscles properly and can create tension instead. If you want to strengthen your pelvic floor, learn Kegels correctly and consider silicone kegel balls for added resistance.
Is there any evidence for the wellness claims?
No clinical evidence supports claims that yoni eggs balance hormones, regulate periods, ease cramps, or improve libido. Those are real concerns with real causes, and a doctor can help with each of them in ways a stone cannot.
Are yoni eggs an ancient Chinese practice?
The origin story does not hold up. A review published in a peer reviewed journal found no historical evidence that jade eggs were used vaginally for any purpose in ancient China. Their popularity is recent and driven by wellness marketing.
What should I do if a yoni egg is stuck?
Stay calm, since the vagina is a closed space and the egg cannot travel anywhere. Squat, relax, and bear down gently as if using the toilet; if there is a string, pull gently while bearing down. If it will not come out after a few calm attempts, or you have pain or bleeding, see a doctor or urgent care rather than continuing to try.
What is a safer alternative to a yoni egg?
For pelvic floor work, Kegel exercises done correctly, with silicone kegel balls for resistance if you like. For sensation, a body safe silicone or glass toy made for internal use. For any pelvic symptoms such as leaking, heaviness, or pain, a pelvic floor physiotherapist, since exercises done wrong can make existing issues worse.
