Relative efficiency of therapeutic donor insemination using a luteinizing hormone monitor

Abstract

A prospective randomized study was performed to evaluate the use of a urinary luteinizing hormone (LH) detection kit with 1 insemination as compared with 2 alternate day inseminations with timing based on previous cycle length and basal body temperature changes. The study involved 60 patients who underwent a total of 264 therapeutic donor insemination cycles using cryopreserved semen specimens. Patients alternated LH-kit timed cycles with cycles timed by non-LH methods for a total of 6 cycles or until pregnancy was achieved. Fecundability rates were 12.3% for LH-kit cycles and 5.3% for non-LH method cycles. The difference in outcome was not statistically significant. However, when the LH kit plus 1 insemination was compared with 2 inseminations timed by conventional methods, there appeared to be a distinct monetary and time expenditure advantage. These findings suggest that sufficient advantage may be derived from use of an LH kit to recommend its use on a routine basis for the timing of therapeutic donor insemination.
