Hi Welcome to Healthcare Magic Forum,
To alleviate your fears, you can ask your Husband to get his Semen Analysis
done. For conception to happen , both Fallopian Tubes should be Patent. You will have the chances to conceive with single patent Fallopian Tube, but there is a risk of Ectopic Pregnancy
which may be detrimental to your health. Kindly chalk out a plan and discuss it with your Husband and Doctor. All the Best, Take Care.
