From the Guidelines
Birth control pills with lower estrogen doses can reduce the risk of yeast infections, and switching to a pill with less estrogen, such as those containing 20-30 mcg of ethinyl estradiol, may be beneficial. Estrogen can promote glycogen production in vaginal tissues, which serves as food for Candida fungi, potentially leading to overgrowth and infection 1. Progestin-only methods like the mini-pill, hormonal IUDs (Mirena, Kyleena, Skyla), or the implant (Nexplanon) contain no estrogen and may be better options if you're particularly susceptible to yeast infections.
Some key points to consider when managing yeast infections include:
- Maintaining good vaginal hygiene
- Wearing cotton underwear
- Avoiding douching
- Considering taking probiotics containing Lactobacillus species to help maintain healthy vaginal flora
- If yeast infections persist despite changing contraceptives, consulting a healthcare provider as there may be other underlying factors contributing to recurrent infections 1.
It's also important to note that the diagnosis of vulvovaginal candidiasis can usually be made clinically, but confirmation with a wet-mount preparation or vaginal culture may be necessary in some cases 1. Treatment options include topical and oral antifungal agents, and the choice of treatment may depend on the severity and frequency of infections, as well as the presence of any underlying medical conditions 1.
From the Research
Birth Control and Yeast Infection Incidence
- The relationship between birth control methods, particularly those with lower doses of estrogen, and the incidence of yeast infections is complex and influenced by various factors.
- A study published in the European journal of clinical microbiology & infectious diseases found that women using combined oral contraception (COC) and long-term levonorgestrel-releasing intrauterine system (LNG-IUS) had the same bacterial composition of vaginal microflora as non-contraceptive users 2.
- However, the same study noted that women using hormonal and non-hormonal intrauterine devices had an increased tendency to have more vaginal colonization with Candida, which can lead to yeast infections 2.
- Another study published in the Journal of Reproductive Sciences found that shifting from a low-dose oral contraceptive to norethisterone acetate (NETA) can be beneficial for women with endometriosis-associated pain, but did not specifically address the incidence of yeast infections 3.
Lower Dose of Estrogen and Yeast Infection Risk
- A study published in the journal Contraception found that lower doses of ethinyl estradiol (EE) combined with progestins can effectively treat acne, but did not address the risk of yeast infections 4.
- The American journal of obstetrics and gynecology published a study that found that fluconazole administration increased the mean serum concentrations of ethinyl estradiol in women taking oral contraceptives, which may have implications for the risk of yeast infections 5.
- However, the study did not directly investigate the relationship between lower doses of estrogen and yeast infection risk.

Other Factors Influencing Yeast Infection Risk
- A review published in JAMA noted that hormonal contraceptives, including those with estrogen, can have various effects on the body, including changes in menstrual bleeding and risks of venous thrombosis 6.
- The review also highlighted the importance of considering individual patient factors, such as medical history and personal preferences, when selecting a contraceptive method 6.
- While the review did not specifically address the risk of yeast infections, it emphasized the need for careful consideration of the potential benefits and risks of different contraceptive methods.
