ABSTRACT
OBJECTIVE: To report on two instances of successful long-term cryopreservation resulting in live births. DESIGN: Case report. SETTING: The patient stored his sperm at a private sperm banking facility, and his partner underwent artificial insemination at an obstetrics/gynecology practice for one pregnancy and at a fertility center for the other. PATIENT(S): One man who stored his sperm before treatment for cancer. INTERVENTION(S): Storage of sperm under liquid nitrogen in a carousel canister system. Intrauterine insemination in which the semen was thawed, washed with human tubal fluid (HTF), and inseminated. MAIN OUTCOME MEASURE(S): Successful pregnancy resulting in live birth. RESULT(S): Artificial insemination with semen cryopreserved for 21 and 28 years resulted in two live births. CONCLUSION(S): This case report describes the to-date longest known successful cryopreservation of sperm, with two live births resulting from IUI. Successful long-term semen storage can be very beneficial for men facing impaired fertility or sterility early in life, so that they have sufficient time to make appropriate family planning decisions.

Foram analisados 71 grupos de maes, em um total de 498 entrevistas individuais feitas pelo Grupo de Incentivo ao Aleitamento Materno (GIAMA), por ocasiao da primeira consulta pos-natal ao Centro de Saude Dr. Sylvio Henrique Braune, em Nova Friburgo-RJ (CSSHB/NF), no periodo de janeiro de 1989 adezembro de 1990, estudando-se as causas de desmame nessa populacao. O indice dealeitamento materno exclusivo no prineiro mes de vida foi de 49,6 por cento e a causa de desmame mais observada (77,9 por cento ) foi a delegacao de que "o leite nao sustenta". O choro do bebe mostrou-se uma importante causa de desmame, porque 68,6 por cento das maes inferiram que "o leite nao sustenta" a partir do choro do bebe. Procura-se, atraves do GIAMA, fornecer apoio e informacoes a mae para capacita-la a lidar adequadamente com as verdadeiras causas do choro do bebe, prevenindo o desmame precoce
