What Causes Abnormal Vaginal Odor?

Can be Bacterial vaginosis too which is not sexually transmitted.
Detailed Answer:
Hello,
Thank you for using HCM to post your health query.
I read carefully your question and I understand your concern.
Trichomoniasis is virtually always sexually transmitted. Although survival on fomites (pillows, towels, door handles, things used publically) has been reported, fomites have no proven role in transmission. Women can acquire the disease from other women, but men do not usually transmit the infection to other men.
Did the doctor saw the trichomonas in a microscope, or verified it by tests, or he just thought it clinically?
Doctors nowdays are a bit mistrustful when it comes to gynecological/genital symptoms, because in many occasions patients don't tell them the truth about sexual history because of the stigma that is related to it. So they treat every symptom there as a sexually transmitted infection just to be sure.
If you are faithful to each other then there is no reason to doubt that.
If the doctor has not verified trichomonas with tests, then there is another diagnoses, that he hasn't considered that give discharge with fishy odor and that is not sexually transmitted. That is Bacterial Vaginosis, which is treated in the same way as trichomonas.
Hope this is helpful and I have reassured you a bit.
Let me know if you need more clarifications.
Otherwise please close and rate the answer.
Regards,
Dr. Papaqako
