Vaginal yeast infections (candidiasis, a common fungal infection) do not directly cause infertility. The yeast stays on the surface of the vagina and vulva and does not reach the uterus, fallopian tubes or ovaries, so it cannot damage the organs that conception depends on. A yeast infection can make sex uncomfortable and harder to time, which is why it is sensible to treat it before or while trying to conceive.

A vaginal yeast infection, also called vaginal candidiasis, is a fungal infection that develops when a yeast called Candida (a fungus that normally lives in small amounts in the vagina) grows more than usual. In a healthy vagina, yeast and protective bacteria sit in balance. When that balance is disturbed, Candida can multiply and trigger itching, irritation, soreness and a thick, white, mostly odourless discharge that is often compared to cottage cheese. It is extremely common: most women have at least one episode in their lifetime, and many have more than one.
When you are trying for a baby, every twinge and every change in discharge can feel loaded with meaning. A yeast infection is uncomfortable and often arrives at the worst possible moment, so it is natural to wonder whether it is quietly working against you. In India, this worry is widespread, partly because yeast infections are so common: the warm, humid climate, tight or synthetic clothing and long days in damp gym or work wear all create conditions in which Candida thrives. Hormonal shifts, including those around ovulation and in early pregnancy, can also make infections more likely just when you are paying closest attention to your body. The concern is understandable. The reassuring news is that the evidence on yeast infections and fertility is clear and consistent, and it is worth understanding properly rather than guessing.

The short answer is no. A yeast infection does not cause infertility and does not damage your reproductive organs. It can create short-lived, reversible obstacles to conceiving in a given cycle, but these disappear once the infection is treated.
No. Candida lives on the surface of the vagina and vulva and does not travel up into the uterus, fallopian tubes or ovaries, which are the organs that matter for conception. Infertility usually stems from problems with ovulation, with the fallopian tubes, with the uterus, or with sperm, not from a surface fungal infection. Published research backs this up: one review comparing roughly 900 women with fertility problems to more than 2,300 fertile women found no association between yeast infections and reduced fertility. In other words, women who get yeast infections are just as likely to conceive as those who do not.
Although a yeast infection cannot make you infertile, it can get in the way of conceiving for a short time, and it helps to be honest about how. Itching, swelling and soreness can make sex painful, so couples often avoid intercourse during exactly the days that matter most around ovulation. The heavy discharge can also make it harder to read fertile cervical mucus, the clear, stretchy, egg-white fluid you may be relying on to time your fertile window. A yeast infection can also alter the natural acidity of the vagina. None of these effects is permanent. Once the infection clears, comfort, discharge and timing return to normal, and so do your chances of conceiving.
Laboratory studies have shown that, in a dish, Candida can reduce how well sperm move and survive after a few hours of contact. That sounds alarming, but a test tube is not the human body, and these findings have not been shown to cause infertility in real life. The practical issue for couples is comfort and timing, not lasting harm to sperm. Treat the infection, and there is no reason it should affect your ability to conceive.

A yeast infection develops when something tips the natural balance of the vagina in favour of Candida. The most common triggers are:
Most straightforward yeast infections clear with antifungal treatment, usually a cream or a pessary (a small tablet placed inside the vagina), or a short course of an oral antifungal medicine. If you are trying to conceive or think you could already be pregnant, tell your doctor, because the choice of treatment changes in pregnancy and some oral options are usually avoided. Treating the infection promptly is the sensible course: it removes the discomfort that disrupts timing and restores normal discharge so you can track your cycle again. Avoid diagnosing recurrent infections yourself because symptoms overlap with other conditions, and reach out to a specialist rather than relying on repeated over-the-counter treatment.
A few simple habits lower the chance of a repeat:
If symptoms are unclear or keep coming back, your doctor may confirm the diagnosis with a swab and rule out the infections that genuinely affect fertility. Cost depends on whether a single confirmatory test or a wider screening panel is needed, on the laboratory, and on the city.

Most mild yeast infections settle with treatment, but it is worth seeing a doctor, and especially a fertility specialist, if you are trying to conceive, in the situations below.
If a recurring infection is making it harder to conceive, a specialist consultation can confirm the cause and rule out anything that matters for fertility.
For most women, a yeast infection is a comfort problem, not a fertility problem. The table below sets out what to expect and where attention is genuinely warranted.
