Pregnancy by insemination of cryopreserved spermatozoa from a man with retrograde ejaculation: a case report.

BACKGROUND

Owing to the prevalence of diabetes mellitus, spinal injuries and aggressive surgical treatment of cancer, the number of younger patients with retrograde ejaculation is increasing. Since medical treatment to restore antegrade ejaculation often fails, several options for accomplishing insemination by these patients, including the use of sperm-rich urine obtained after masturbation and in vitro fertilization with sperm retrieved from the seminal tract, have been reported. We used the least invasive and most inexpensive procedure in a patient/couple with this condition.

CASE

A 23-year-old man suffered from retrograde ejaculation after a spinal injury. He could achieve erection and engage in sexual intercourse but seldom had an orgasm or the sensation of ejaculation. We obtained spermatozoa from urine produced after masturbation at home and froze them. We used these frozen-thawed spermatozoa for intrauterine insemination, leading to the term birth of a healthy infant.

CONCLUSION

In selected patient/couples, frozen spermatozoa obtained from postmasturbation urine can be used successfully for intrauterine insemination. This minimally invasive and most inexpensive procedure should be tried before planning in vitro fertilization.
