A yeast infection occurs when the fungus Candida albicans starts growing excessively in the vagina. The fungus usually exists in the body in small quantities and is harmless. It causes infections when there is an imbalance of beneficial bacteria in the vagina. These bacteria are supposed to keep the Candida fungi at bay, but when they become imbalanced, yeast overgrows.
The following are some of the common signs that a woman having a yeast infection will exhibit:
Some factors that may contribute to a yeast infection include:
While intercourse can result in yeast infections, it is not a sexually transmitted infection, as it can also affect those who do not engage in intercourse.
The vagina is a highly regulated biological ecosystem. Under normal circumstances, beneficial bacteria called Lactobacilli predominate in the vagina, ensuring that the vagina has an optimal pH range of 3.8 to 4.5. This not only protects the vagina from harmful infections, but it also creates a pathway that supports sperm survival and movement toward the egg for fertilisation.
If a yeast infection is contracted, the balance between these two organisms is disrupted. The Candida fungus takes over and pushes out the beneficial bacteria, resulting in altering the vaginal environment and microbial balance. The changed conditions are harmful not only to the body but also to sperm cells and can disrupt fertilisation.
This question and others must come up in the minds of women who frequently go through yeast infections:
| Question | Answer |
|---|---|
| Can a single yeast infection permanently damage fertility? | Yeast infections alone cannot cause permanent damage to fertility. |
| Do yeast infections spread to the uterus or fallopian tubes? | Yeast infections are usually confined to the vagina and vulva, unlike bacterial STIs. |
| Can recurrent yeast infections affect fertility? | Yes, but indirectly. Persistent infections can disrupt the vaginal environment. |
| Can untreated yeast infections become a bigger problem? | Infections that are left untreated and ignored can worsen over time. They may also be linked to other reproductive health complications. |
| Can fertility be recovered following the treatment for yeast infections? | Generally speaking, recovery from the condition restores a natural vaginal environment conducive to pregnancy. |
To put it simply, yeast infections on their own are unlikely to make a woman permanently infertile. However, they can impact the healthy vaginal environment, which poses further complications.
While yeast infections may not directly cause permanent infertility, they create several obstacles that make it difficult to get pregnant during any given cycle.
Candida albicans can be directly toxic to sperm, reducing sperm motility The fungus can also reduce sperm motility and cause them to clump together. This is called agglutination. All of this combined can reduce the number of healthy and functional sperm that can reach and fertilise an egg.
Around the time of ovulation, cervical mucus naturally becomes thin and slippery, resembling a raw egg white, to help the sperm travel through the cervix. When a yeast infection occurs, the texture and composition of the mucus can change, becoming thicker. This reduces the window of opportunity for fertilisation each month.
On the other hand, women who experience yeast infections frequently may have an underlying condition such as uncontrolled diabetes, hormonal imbalances, and immune system issues. These conditions, too, can impair fertility. Here, yeast infections are not the cause, but rather a warning sign.
One particular barrier to conception during a yeast infection is simply painful intercourse. Vaginal inflammation makes it painful for women to have penetrative sex, and it can lead to them missing the fertile window of 5-6 days.
Yes, men are susceptible to Candida infection in the penis, which is called penile candidiasis. Penile candidiasis may occur following sexual contact with a partner who has a Candida infection, and men with this condition can suffer from symptoms such as redness, itching, and rashes on the head of the penis.
Though it does not affect male fertility in the long term, it temporarily interferes with it due to low sperm motility, viability, and quality.
This is a list of things that one should do to keep the vagina healthy and fertile:
In most cases, a yeast infection will not cause any long-lasting issues concerning female fertility. But such a condition may cause some difficulties on the way to conception, such as an unfavourable environment for sperm, a change in the characteristics of cervical mucus, as well as unpleasant sensations that may result in too much pain during sex. Sometimes, recurrent infections can also point to hormonal or immune system disorders.
If women lead healthy lives and take care of their sexual well-being, they may reduce the risk of yeast infections. Nevertheless, it needs to be understood that yeast infections can be treated and prevented.
