After my BV is cleared, it comes back when I have sex. Can man pass BV to woman?

To answer your question, there are two possibilities:

  1. Your old BV might not have been completely cleared. BV bacteria produce amines. When these amines are fully dissolved in liquid-like vaginal secretion, there is little or no odor. But when the environment becomes alkaline upon exposure to semen, amines release ammonia gas. You may smell the pungent fishy odor. Semen triggered the odor release. This is a sign that you may have had BV before you had sex. In this case, your BV is not caused by man. This is a common BV-related symptom.
  2. Your BV was completely cleared but your partner might harbor some BV-related bacteria and gave BV back to you. In this case, it happens quietly and it does not show a noticeable odor immediately after sex. It takes some time for BV to develop after the initial infection. The last section of this article explains how an intimate partner may pass BV back to you.

Men do not get BV. This means that even if men harbor BV-related bacteria, it may be temporary. While you are doing BV treatment, it would be a good idea to refrain from having sex for at least 2 weeks. You should let your partner clean well with soap and keep good hydration to flush the bladder with strong urine pressure. This way, after your BV is cleared, your partner will also be clean.

The partner may be a carrier if the infection is associated with group B streptococcus. Even though he may not have any noticeable symptoms, a study showed that spouses of group B-infected women tested positive for the same type of group B streptococcus in their urine. Thus, men can be a source of re-infection. Since men do not have group B streptococcus infection, their carrier status may be temporary and may not last for two weeks. It would be a good idea to refrain from having sex for at least 2 weeks while you are treating group B infection.

However, if BV is infected by special pathogens like Ureaplasma,  men may get an infection and may need treatment with antibiotics.  It is easy to know if a man is infected by Ureaplasma. A typical symptom is pain during urination. If so, a urologist can provide treatment for a man.


Other BV care products use a one-size-fits-all approach. We provide personalized or customized care.

Personalized care is better care. We offer 7 different products to clear stubborn recurrent BV in women of different ages and health conditions.

We would be better able to help you choose a suitable product if you could tell us your age and health conditions like birth control, IUD, breastfeeding and hysterectomy, and cancer treatment.

To date, we have helped over 100,000 women with severe recurrent BV and all other products including antibiotics and boric acid have failed to find rapid and complete relief.

Other products may clear BV but cannot stop BV from coming back. NeuEve is the only product that can remove BV and stop recurrent BV from coming back.

Some stubborn recurrent BV cases are caused by Ureaplasma, which naturally resists most antibiotics used for BV treatment. But BV Clear can clear it. For more information about how BV Clear can clear bad bacteria, you may find these articles helpful:
