Bacterial vaginosis is one of the most common causes of changes in vaginal discharge in women of reproductive age. Most of the time, it is not an emergency, but it becomes relevant when there are persistent symptoms, recurrences or when investigations and procedures are being planned in the context of infertility.
In practice, the challenge is not only “how do we treat it”, but also “when do we treat it” and “how do we make sure it does not interfere with the next steps”, especially before In Vitro Fertilization (IVF) or before other procedures.
What bacterial vaginosis is and why it occurs
Bacterial vaginosis (BV) is not, in itself, a classic sexually transmitted “infection”, but rather an imbalance of the vaginal flora. Normally, the vagina has a bacterial balance dominated by lactobacilli, which maintain a more acidic pH and protect the mucosa. In bacterial vaginosis, lactobacilli decrease and other bacteria may become predominant, which changes the pH and may cause symptoms.
Its occurrence may be favored by several factors: hormonal changes, intravaginal douching, changes in sexual partner, use of irritating products for the intimate area or certain antibiotic treatments that may disrupt the flora.
For clarity, bacterial vaginosis can easily be confused with other common causes of vaginal discomfort, and making the distinction matters when choosing treatment:
Bacterial vaginosis: usually an unpleasant odor, sometimes described as “fishy”, white-gray discharge, elevated pH. Itching may be absent.
Candidiasis: intense itching, redness, white clumpy discharge. The pH usually remains normal.
Trichomoniasis: yellow-green, frothy discharge, odor and sometimes dysuria. It requires specific treatment and partner evaluation.
Signs and symptoms: when bacterial vaginosis is suspected
When they appear, the symptoms of bacterial vaginosis are usually related to changes in vaginal discharge and odor. Some people describe the odor as being stronger after sexual intercourse or after menstruation. Discomfort may be mild or absent.
An important point, especially in the context of infertility and procedure planning, is that bacterial vaginosis can also be asymptomatic. The absence of symptoms does not rule out a vaginal flora imbalance, and in certain situations the doctor may recommend evaluation depending on gynecological history and the next planned steps.
If fever, significant pelvic pain, unusual bleeding or marked pain during intercourse occur, the issue should not be postponed. These signs may suggest something other than uncomplicated bacterial vaginosis and deserve prompt evaluation.
Correct diagnosis: which tests are useful and what is not enough
The diagnosis of bacterial vaginosis is based on the combination of clinical evaluation and simple tests focused on pH and the microscopic appearance of vaginal secretions. In the office, the doctor may observe the typical changes and may recommend sampling for confirmation, especially when symptoms are recurrent or when a procedure is approaching.
Self-diagnosis based on “odor” or the appearance of discharge can lead to inappropriate treatments, for example repeated antifungal treatment in the absence of candidiasis. Over time, this approach can worsen discomfort, delay correct treatment and complicate infertility planning.
In addition, when there is pain, bleeding, dysuria or suspicion of an associated infection, the doctor may indicate further tests, not to “complicate” matters, but to ensure targeted and safe treatment.
How bacterial vaginosis influences fertility
In most cases, bacterial vaginosis is a manageable issue, but it can become relevant for fertility for several reasons.
First, the imbalance of the vaginal flora is associated with a less favorable local environment, and low-grade but persistent inflammation may contribute to discomfort, recurrence and repeated treatment episodes. In some individuals, bacterial vaginosis is associated with a higher risk of ascending infections in certain contexts, which is why doctors are more cautious before procedures involving intrauterine instrumentation.
Second, when infertility is being discussed, the focus is on “reducing the variables” that may interfere with evaluation and procedures. Even though bacterial vaginosis is not the sole cause and does not explain every situation, it is one of the more easily correctable conditions, with practical impact on comfort, sampling and procedural timing.
Third, recurrence in bacterial vaginosis, meaning repeated episodes over several months, can be frustrating and can keep “shifting” the schedule. In such situations, the approach is not limited to reflexively prescribing treatment, but rather to clarifying the diagnosis, identifying contributing factors and creating a strategy to reduce recurrence.
What is recommended before fertility procedures
When a procedure is planned in the near future, the decision is individualized. There are differences between a symptomatic case, an asymptomatic one, a history of recurrence or the presence of other risk factors. Even so, several principles are useful.
Before IVF / ICSI and embryo transfer
Before starting or moving forward with the major steps, the medical team aims to minimize avoidable risks and ensure the most stable possible setting. In this sense, if there are symptoms or suspicion, evaluation and treatment may be recommended before the procedure in order to avoid discomfort, repeated sampling or delays.
For a clear understanding of the stages and key moments of the process, a useful reference is In Vitro Fertilization (IVF) – complete guide, especially when planning includes tests, monitoring and fixed intervals.
Before intrauterine insemination (IUI)
In the case of intrauterine insemination (IUI), the discussion is similar. If there are symptoms or a recent episode, the doctor may consider it useful to treat it before the procedure in order to reduce discomfort risk and proceed in an optimal setting.
Before investigations and evaluations, including ultrasound
Correct evaluation of the reproductive system often includes transvaginal ultrasound, which helps assess the uterus, ovaries and several elements relevant in infertility. When there is discomfort or changed discharge, it is useful for the doctor to know in advance, in order to adjust the approach and decide whether treatment is needed before the next steps.
In the context of infertility and IVF preparation, there are situations in which the goal is to make the examination as complete and comfortable as possible, and sometimes transvaginal ultrasound in infertility before IVF is discussed explicitly, depending on the evaluation stage.
A few practical points, where the list really helps
- If there are active symptoms, odor or changed discharge, evaluation and treatment are generally priorities before a procedure.
- In recurrent bacterial vaginosis, a more structured plan may be needed, not just repeated treatment without confirmation.
- Intravaginal douching and irritating products tend to worsen the imbalance. Avoiding them often helps in the medium term.
Treatment of bacterial vaginosis: principles, recurrence and what to watch afterward
Treatment for bacterial vaginosis is determined by the doctor depending on symptoms, recurrence, gynecological history and pregnancy or procedure plans. There are local options, intravaginal, and systemic options, oral, and the choice depends on the context.
An important goal is symptom resolution and reducing the likelihood of recurrence. In practice, recurrence of bacterial vaginosis is relatively common and does not automatically mean that the treatment was “wrong”. Rather, it means that the vaginal flora returns to balance more slowly or that contributing factors remain present.
In the area of intimate health, a balanced approach includes avoiding irritants, limiting intravaginal douching and discussing contraception and factors that may disturb the flora. In some situations, the role of probiotics as an adjunct is also discussed, but they do not replace treatment when the criteria for bacterial vaginosis are clear.

What helps in the medium term for intimate health
In many cases, the difference between an isolated episode and repeated episodes has to do with everyday habits and repeated exposure to irritating factors. In addition, during periods when procedures or investigations are being planned, simplifying the intimate care routine and avoiding “experiments” with local products can reduce fluctuations and make the timeline more predictable.
If there are questions related to the steps of IVF and what is assessed before procedures, the medical perspective can also be complemented with explanations focused on the clinical pathway, including in In Vitro Fertilization (IVF), when additional context is sought about decisions and stages.
For many people, a more human perspective on the process, expectations and the way the stages are experienced is also helpful, especially when “pauses” appear because of treatable situations. In this sense, reading about In Vitro Fertilization (IVF) – patient experience may also be relevant.
As for monitoring and evaluation, when the goal is to correlate symptoms with examinations, a useful reference remains Transvaginal Ultrasound, as a gynecological evaluation tool in multiple contexts.
Frequently Asked Questions
What are the most common symptoms of bacterial vaginosis?
Usually, white-gray discharge and an unpleasant odor appear, more noticeable after sexual intercourse or after menstruation. Intense itching is more typical of candidiasis than bacterial vaginosis, although discomfort may still be present.
Can bacterial vaginosis occur without symptoms?
Yes. Some people have no symptoms, and the imbalance is identified during consultation or in the context of investigations. In infertility care, this situation is managed individually, depending on the stage and the immediate plans.
Can bacterial vaginosis cause infertility?
It is not correct to consider it a single direct cause of infertility, but it can be an important variable. It is associated with local imbalance and inflammation, and in certain contexts it may increase the risk of ascending problems. In addition, recurrence can disrupt the planning of procedures and evaluations.
Should bacterial vaginosis be treated before IVF or embryo transfer?
If there are symptoms or a recently confirmed episode, the doctor will often recommend treatment before the major steps in order to avoid discomfort and delays. The decision depends on timing, symptom severity and history of recurrence.
Can insemination, IUI, be performed if bacterial vaginosis is present?
In general, if active symptoms are present, it is more prudent to evaluate and treat it beforehand. If there are no symptoms, the doctor decides based on context, because the goal is the safest and most predictable setting possible.
How long does bacterial vaginosis treatment take and when does everything return to normal?
The duration varies depending on the recommended regimen, and symptoms may improve quickly. However, the balance of the flora may stabilize over time, and in recurrent cases a broader strategy is useful, not just repeated treatment.
Why does recurrent bacterial vaginosis occur?
Recurrence may occur because the flora recovers slowly or because contributing factors remain present, such as intravaginal products, douching, irritants or hormonal changes. Confirming the diagnosis and identifying the triggers are key steps.
Does the partner need treatment in bacterial vaginosis?
In general, bacterial vaginosis is not managed in the same way as a classic sexually transmitted infection. Still, if there are recurrences, the doctor may discuss the context and may recommend additional evaluation to rule out other infections or associated causes.
