gets fertilized with the stored sperm, producing a clutch of many eggs, all
with the sperm from that one cloacal kiss. |

We knew that my husband does not have sperm 5 years ago. But at that time,
we thought that life is easier without babies.
We changed our idea last year. we got ourselves checked in more detail. But
the doctor could not figure out why my husband does not produce sperm. Then,
we made a hard decision to use sperm donor.
I tried IUI once with clomid. Failed.
Now this is my second cycle with clomid. Hopefully it will work this time. |
