Objective:
To identify variables, obtained from historical factors and sperm analysis, associated with greater chances of pregnancy in infertile couples.
Methods:
The study was carried out in Córdoba, Argentina. The characteristics of 247 couples consulting for infertility who achieved pregnancy within 3 years of their first visit were compared with those of 312 couples who did not become pregnant. We evaluated the relationship between the age of the woman and her partner, the type and duration of infertility, length of the last three menstrual cycles, history of pelvic surgery in the woman, and testicular volume, sperm density, motility and morphology in her partner, and the achievement of pregnancy. For the analysis, logistic regression was used.
Results:
Six variables had a predictive value: sperm morphology, the woman's age, type and duration of infertility, her history of pelvic surgery, and duration of menstrual cycles.
Conclusions:
The best prognosis for future fertility in infertile couples is correlated with a higher percentage of normal sperm morphology, younger woman's age, secondary infertility, fewer years of infertility, negative history of pelvic surgery, and abnormal menstrual cycles.
