Hello and welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Yes, yeast or any other infection in the vagina does affect the fertility by creating a hostile environment for the sperms. However, once the infection is treated successfully, the environment regains its normalcy and thus fertility can be re-achieved. For yeast infection, please take some anti-fungal vaginal or systemic treatment. Along with it, use Lactobacilli vaginal ovules for at least 15 days and Lactobacilli perineal wash too. This infection can spread sexually also. Hence, irrespective of the symptoms to your husband, both of you should take the simultaneous treatment. I would advise both of you to follow the undermentioned tips for successful anti-fungal treatment: 1. Till both of you are declared completely cured, observe complete sexual abstinence. 2. Shave the private parts clean. 3. Clip the nails short - flush to the skin. 4. Boil your underwear daily. Use panty liners. With the successful treatment for the fungal infection you can definitely conceive provided: 1. You are forming the eggs regularly: you may ensure this by ultrasonography ovulation monitoring. 2. Your tubes are patent and there is no pathology in the uterine cavity : Hysterosalpingography, Laparoscopy and Hysteroscopy can provide the information about these factors. 3. Husband has sufficient healthy sperms: Semen examination will give the information. Please report to your gynaecologist for these investigations, treatment and further advice. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Nishikant Shrotri
