Spontaneous pregnancy in couples waiting for artificial insemination donor because of severe male infertility.
OBJECTIVE
To assess the spontaneous fertility in couples with severe seminal conditions while waiting for artificial insemination donor.


METHODS
Prospective follow-up during a period of 24 months.


METHODS
University Medical School.


METHODS
There were 285 couples in which the male had a very severe seminal pathology: 166 azoospermia, 86 oligozoospermia and 33 severe asthenozoospermia.


METHODS
Pregnancy rates after being included on waiting list.


RESULTS
The spontaneous pregnancy rate was 3.2% (9/285), per month spontaneous pregnancy rate being 0.13%. Spontaneous pregnancy rate was 0% in azoospermia (0/166). versus 7.6% (9/119) in non-azoospermia cases. Spontaneous pregnancy rate was 8.5% (4/47) in the group with less than 0.1 million motile sperm/cc, 6.5% (3/46) in the group between 0.1 and 1 million/cc and 7.7% (2/26) in the group with 1-2 million/cc.


CONCLUSIONS
In a 2-year follow-up, pregnancy rate among non-azoospermic couples before undergoing artificial insemination was 7.6%. Extramatrimonial pregnancy (based on anamnesis and sperm analysis) seemed to be uncommon. Even in cases with less than 0.1 million of motile sperm/cc there was not a negligible spontaneous pregnancy rate.
