Patients having intrauterine insemination for fertility treatment can be reassured that the use of cryopreserved sperm instead of fresh is not associated with inferior outcomes.
The largest study of its kind, whose results are presented today at the 38th annual meeting of ESHRE, found no difference in pregnancy rates between cycles using cryopreserved or fresh sperm samples.
The results of the study, presented today by Dr Panagiotis Cherouveim from Massachusetts General Hospital and Harvard Medical School, USA, were based on an analysis of 5335 intrauterine insemination cycles performed at his center between 2004 and 2021.

MILAN, Italy — Good news for couples using fertility treatments to conceive a baby. In the largest study to date, researchers have shown that frozen sperm works just as well as fresh sperm for insemination and pregnancy.
“Patients undergoing IUI should be counseled about the non-inferiority of frozen sperm,” says Dr. Panagiotis Cherouveim, a researcher at Massachusetts General Hospital and Harvard Medical School, in a media release.
Cryopreservation is the most favorable choice for storing sperm, and in some places, a requirement for using donor samples. The sperm can stay frozen for up to six months and gives fertility doctors time to screen for infections before use.
…What are the benefits of using cryopreserved sperm?
… There was no difference in pregnancy rates using fresh or frozen samples. The only difference seemed to be the time it took to receive a positive pregnancy result. People using frozen sperm took longer to get pregnant than those who used fresh sperm.
… “The fact that our data did not reveal any significant difference in success between the utilization of fresh ejaculated and frozen sperm, except in a subgroup of patients given oral ovulation-inducing agents, is very reassuring to all involved,” Cherouveim adds.
