Many vagina owners don’t realize that semen can be the cause of unpleasant smells from their lady bits, but there are actually a few reasons a man’s “elixir” may cause your yoni some distress.

Like anything that contains proteins, the smell of semen changes when it decomposes inside the vagina. 

But that’s not to say you don’t have a healthy vagina or that you should douche or wash inside your vagina, because that will weaken your vagina’s own immune system!

Vaginas are amazing self-cleansing pleasure palaces with an immune system of their own.

The key to optimum functioning and a healthy vagina lies in its pH and a sufficient amount of healthy bacteria. A healthy vagina is fairly acidic, with a pH value between 3.8 – 4.5, which is perfect for the healthy bacteria to thrive, but too acidic for “bad” bacteria to grow.

When the pH becomes more alkaline, i.e. a higher number on the pH scale, it becomes a great place for “bad” bacteria to grow, which will produce a different kind of vaginal smell.


So, a healthy vagina is supposed to have a certain odor. But in the case when the smell changes after your partner has ejaculated inside you, why does this happen?


Semen has a pH of 7.2 – 8, which, when ejaculated into the vagina will affect the vaginal pH balance temporarily. If the immune system of the vagina is healthy to start, with an acidic pH value, and a sufficient amount of healthy bacteria, the occasional dose of semen normally won’t cause any trouble.

The male body combines the best of vital essences to produce semen, to ensure it is high-quality baby-making juice!

According to the Chinese Taoist tradition, men will benefit greatly from not wasting this precious liquid every time they have sex. And from the perspective of a Tantrika, why ejaculate when your orgasm actually doesn’t depend on it???

Through many years of teaching men to separate orgasm from ejaculation our team of Authentic Tantra teachers and I have seen how rewarding this is for these men and their female partners.

The men experience an increase in vitality and physical functioning (including their ability to last longer) as they retain their semen for 4-8 weeks at a time, while enjoying multi-orgasmic love making sessions.

Their female partners enjoy longer and multi-orgasmic love-making sessions, and their vaginal pH is less likely to be thrown off-balance by semen.

  1. Thanks for your comment. The questions was not “what causes vaginal odor in general?”. This video was in answer to a question a viewer sent us regarding semen specifically making her vagina smell different. We have several other articles that address the issue of how to keep your vagina happy and healthy overall.These other articles address the topic of overall vaginal health and BV. As I said, this video and article were meant to specifically address the issue of semen inside the vagina.

    1. Get a boric acid vaginal pill. And some women probiotics. The boric acid ONKY GOES IN THE VAGINA!! The probiotic daily like I use “Queen v probiotics, from Walmart.. blue cap” both together out my vagina back into perfect functionality.

  2. Love to get some Insife, have a random on occasion problem with this not sure if it pertains to my boyfriends sdcrestions… but just curious if even a long bath could trigger this.
    Thank you,

    1. Hello Patty. Thanks so much for asking. Here is a podcast Interview I did awhile back with women’s sexual health expert S.Denise Jefferson. I have a few other interviews with other female sexual health experts as well.

    1. No! No! P push it out. You don’t have to douche every time you have sex. I’ve been with my husband for 20 years. And we have a very healthy sexual relationship. Everyday or every other day. I don’t douche. I don’t have issues. However I do pee afterwards always. Wipe it well. I have a healthy vagina. Rarely I’v had a musky smell from him. Rare very rare but I do not use stuff to make my pH balance worse. Semen already plays a part in doing that it’s very alkaline and we are acidic. So douching would make it even worse. If you read studies simply using the bathroom afterwards is your best bet. You can push most of it out.

  3. Ok so this is a little embarrassing to say but it seems like everytime me and my man do are thing I have a smell and I just don’t understand why I keep getting BV and it is starting to annoy me, so yes if you have a solution I would like to try it please

  4. What is the right ingredients to douche with? I’m so confused on rather to douche or not to douche. Please advise.

  5. Hello! I’d really appreciate it if you could share with me the formula because I’m one of those women that constantly deal with BV

    1. I will be doing a radio show about this topic on March 1st. I will ask this question to my quest, sexual wellness expert Nina Helms.
      You can learn more here-

  6. What is the right douche for the fishy smell I’ve never had this problem before and it just came on one day after sex. I don’t have any pain or itching just a smell that I’ve never had before, and ive only been with my fiance for the last two years so no multiple partners. Please email me back I’m not sure I’ll be able to catch the pod cast

    1. You should go to the doctor if you have never had this problem before. There are ways to treat at home of you know what you have but it could be a number of things

  7. So wat type of douche is best. My partner has bad smelling sperm and it through a my off. Is it something he can do as well?

  8. No it is not good to douche at all period…whether your ph is right or not. If you’ve gone to the doctor and they prescribed you an antibiotic and it didn’t help then there is something else wrong. I’ve had bv a cpl times in the past and the antibiotics my doc prescribed me worked every time. She explained what the question was that she was asked. Ever time my boyfriend and I have sex, usually the next day I will smell because I now know it’s because of his semen breaking down inside of me. Just because for some reason you’re having reoccurring infections doesn’t mean she didn’t explain it correctly. If I were you I’d go get your shit checked out by a different doctor. Oh and p.s. not that many women suffer from vaginal infections so idk where you got that # from

    1. I’m not sure where you got your information but you are completely wrong. There are LOTS of women who have had or struggle with some type of infection. You are also wrong about douching, you can make your own douch that Is very healthy and will help your pH stay balanced for anyone who has that probben such as myself. You clearly need to get your head out of the sand and do some research

      1. Douching is a topic of considerable debate. Every female sexual health expert I have spoken to in the past 10 years speaks strongly AGAINST douching. All of these women I have spoken with are experts in the field and many have multiple PHD’s related to women’s sexual health. That being said, I personally have also learned about ACV douches and some of the other methods you mention above to reset healthy vaginal PH. In regards to BV, which btw was not actually the topic of this video or this article, the consensus seems to be to go to your gyno and get an antibiotic. Then attempt to maintain healthy vaginal PH with a healthy diet and probiotic supplements. In regards to the yoni smelling different after semen, my favorite female sexual health doctor suggests inserting a probiotic capsule into the vagina to boost the beneficial bacteria and re-establish the acidic environment.

  9. If you have BV, you should NOT douche. Talk to your doctor about a probiotic vaginal suppository. It has helped me with my reoccurring BV.

  10. My pH gets thrown off easily. I’ve has numerous bacterial infections. Make your own douch at home with ACV with the mother and filtered water. This also works with the smell if you have let your partner ejaculate inside you. You can also use a mixture of water and PLAIN ORGANIC YOGURT. Tea tree essential oil is also great for bacterial infections. Mix it with some coconut oil if you are sensitive and apply it using a cotton ball or pad

  11. Ummm B.V. is not difficult to get rid of. In fact it’s quite simple when you go to your OB/GYN and get metronidazole. Treats it just fine. And if a woman doesn’t know that she has that oh my god she’s stupid. It has a very distinct smell it has a very distinct white texture it’s not normal at all. It’s just a pH in balance and it can be resolved very quickly with metronidazole!

    1. Also recurring bacterial vaginosis probably is an indication that the doctor prescribed too high of a dose of metronidazole you don’t need an extremely high dose to get rid of it especially when you first catch it. When I first had it when I was young 19 my first OB was giving me way too high of a dose and it was burning the crap out of me and then I’dI get yeast infections and then I’d have to be treated with an anti-fungal and it was just reoccurring. I finally went to a specialist at age 20 and have been with him since he stopped that cycle. He knows what to do properly. He lowered the dose and I’ve had it twice in my life. I don’t have a smell. I have never douched because wow don’t need to . Like my doctor has explained to me the Vagina is a self cleaner, and it needs to stay at its normal pH and if you start douching and messing around with it you can really mess it up. Opening it up for Bacterial vaginosis . Doctors know the difference between BV and an STD as well. There is over the counter metronidazole but I don’t recommend it. I recommend using the antibiotic pill form. Because the metronidazole comes in tubes you put it directly in your vagina and then your pH balance can get really messed up. OTC don’t always work right .

  12. Soaking in a tub with baking soda eliminate the odor from bv and restored the ph levels to normal in a woman. I don’t measure it. I just pour a little in a tub with water and sit and soak. But after soaking, you have to shower after that to get the baking soda off of your body…

  13. Natural remedy for vaginal odor:
    Take a tampon (in applicator) and soak it in raw organic apple cider vinegar.
    While tampon is soaking, run a bath. Once water has reached level where it will cover lady bits, pour one cup of acv in bath water. Then measure 1/2 cup Epson salts. Add one teaspoon tea tree oil to Epson salts and pour mix into bath water. Soak for twenty to thirty minutes in bath.
    After bath insert tampon that has been soaking in acv into vagina and leave in for at least 4 hours (overnight is best)
    Do this routinely after sex and it should eliminate/help with vaginal odor 🙂

  14. So me and my boyfriend had sex 7 times in a day and each time he came inside of me. I was on my period whenever we started but now I’m not. I’m vagina has a weird odor coming from it, its really really sore and swollen, and all of this is making me a little scared. I don’t have any STDs and neither does he. Is there any way that I can fix this. Its really really scaring me and I don’t know what to do. Please help.

  15. I have been suffering off and on… I am currently dealing with it because of my partner, mostly. I do everything I can to keep it in check but am looking for as much information and help as I can as like you pointed out here… There really aren’t many resources other than other women for help. I even had a nurse shame me when I suggested I had BV and insisted it was yeast… even made fun of me in the hallway to another nurse. I called my doctor when the results came in to tell her what had happened after I was proven right yet again… Reoccurant BV pisses off nurses.. go figure, we arent aloud to know our own bodies

  16. I would love to know what you suggest. I have had recurring BV with my current partner and it seems his semen is the problem. I douche with a 50/50 mix of hydrogen peroxide which keeps it at bay, then when we are apart my BV goes away. I would love to be able to just be normal again and not have to go through the trouble of always having to do this

  17. How would u treat b.v your the I’ve heard say doche is the 1st thing you should do .which I believe as well. What is the right formula?

  18. Hello I think that’s what is happening to me. I have been to the doctors several times they have giving me medicine to supposedly cure this bacteria but nothing seems to work. I don’t know what to do. You said maybe douching my help. I’ve done that too. What do you suggest.

  19. I’m interested in hearing the “complete protocol” for BV. I dont usually have bad or fishy odor, however after my boyfriend ejaculated inside me, I noticed my smell was different but not bad, then a few days later it became fishy.

  20. I searched high and low for answers to my vaginal odor following sex with my spouse of 20 years. I wore cotton undies, visited the clinic, tried changing my diet, tried changing his diet. We finally came to an agreement that he would have a vasectomy, we were desperate to solve the problem, we have our beautiful children and I have since had a hysterectomy. The vasectomy worked! We may now have a full sex life without odor worries ever again. There is no talk online about dying semen possibly causing female odor. All I could find were thins pointing to female issues such as BV, or imbalanced ph, yeast problems etc…but, in trying to fix all those issues and nothing remedying the problem, there was only one thing left to consider..his sperm. It worked, and the problem is gone 🙂

  21. I’ve been blaming my bg that I smell because of his semen deposits, he categorically denied it. Help! His semen smells because his diet is atrocious. What do I do?

  22. I would also like to know the answer to that question. I have looked and can not find a definitive answer. Everything just says that It can upset the ph for a short time. Is that time as long as semen is inside you because that can be up to five days.

  23. I have a vasectomy so there’s not ever a time that I don’t cum in my gf really but this happens sometimes not all the time. Is there something she can take or do to prevent this? Thanks!

  24. So I’ve been dealing with the same man for 3 years , everytime he ejaculates in me there is a smell the day after . I’ve been off nexplanon for over a month because it was causing too many issues & no smell at all , he’s been pulling out . Last night we had sex , this afternoon I’m
    Smelling like fish like I used to , I easily get BV , even due to tampons sometimes . Not only does this mean he cummed in me but now I have BV again . Why does this happen with only him .. he’s fit he works out no alcohol or weed … not sure what it is . Pls help .
