[Use of ultrasonic folliculometry and LH determination in artificial insemination with donor semen]

The results of ultrasonic determinations of follicular growth and determinations of serum LH-levels were analysed in 34 patients who were artificially inseminated using cryopreserved donor semen (AID). 22 of them became pregnant. The ultrasonic findings had contributed to perform AID optimally, where as the determinations of LH did not surely indicate ovulation in each case. Frequency of inseminations per cycle was reduced by means of ultrasonic observations of follicle. The chance of success of artificial insemination using cryopreserved spermatozoa was decreased by delay of maturity of follicle. A peak of LH-concentration in serum was not detectable in 27 per cent of patients by one estimation daily.
