Hello and welcome to HCM
Medullary sponge kidney
is agenetic cystic disease of the kidney and it has nothing to do with conception.
The frequent episodes of UTI that you have mentioned occur in sexually active women.
To avoid frequent episodes of UTI, pass urine after every act of intercourse. Drink plenty of water. Add more citrus fruits to diet. Inorder to treat urinary tract infection
, get an antibiotic prescribed by your doctor.
Since both your and your partner's fertility
tests are normal there is some other reason for inability to conceive.
Time your cycles for the period of ovulation by basal body temperature
and cervical mucus examination.
If not successful get checked for anti-sperm antibody in the cervical mucus if you haven't got it before.
Thanks and take care
