ABSTRACT
OBJECTIVE:
To assess the spontaneous fertility in couples with severe seminal conditions while waiting for artificial insemination donor. STUDYDESIGN:
Prospective follow-up during a period of 24 months.SETTING:
University Medical School.PARTICIPANTS:
There were 285 couples in which the male had a very severe seminal pathology 166 azoospermia, 86 oligozoospermia and 33 severe asthenozoospermia. OUTCOMEMEASURES:
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.CONCLUSION:
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.
