Mycoplasma is a type of microorganism that sits between bacteria and viruses. It is slightly smaller than bacteria but much larger than viruses. It can pass through bacteriological filters and can be cultured on specific media. Mycoplasma typically infects our respiratory tract as well as our urinary and reproductive systems, causing infections in these areas. However, mycoplasma does not enter the bloodstream and generally does not transmit to infants or young children through blood or the placenta, hence it usually does not affect pregnancy. Yet, if medications against mycoplasma are taken during an infection, there might be some effects on pregnancy. It is essential to consult a doctor or pharmacist to decide whether to use medication or not.
