“…Modified Earle's solution was used to obtain one of the successful pregnancies reported by Edwards et al (1980b) and in more recent studies in our laboratory, blastocysts and pregnancies have been obtained from fertilization and culture in simple media used routinely for culture of mouse embryos (Trounson et al, 1980b Adams, 1979). Before the 8-cell stage, human embryos are confined to the oviducts in vivo (Croxatto, Ortiz, Diaz & Hess, 1979). Improved culture media and techniques and survival rates of different cleavage stage embryos are presently being investigated to determine the optimum procedures for maximum pregnancy rates.…”

Summary. Oocytes were obtained from patients with tubal infertility at fixed times after the onset of the endogenous LH rise or hCG injection, and were inseminated immediately after recovery or after periods of 4\ p=n-\ 4\ m=1/ 2\ , 5\ p=n-\ 5\ m=1/ 2\ and 6\ p=n-\ 6\ m=1/ 2\ h in culture in vitro. Delayed insemination resulted in a marked increase in the proportion of oocytes that were fertilized and developed to normal embryos and maximum rates occurred after 5\ p=n-\ 5\ m=1/ 2\ h in culture ( 0\ p=n-\ \ m=1/ 2\ h, 26%; 4\ p=n-\ 4\ m=1/ 2\ h, 50%; 5\ p=n-\ 5\ m=1/ 2\ h, 89%; 6\ p=n-\ 6\ m=1/ 2\ h, 69%). The range and mean (\m=+-\s.d.) intervals from insemination for the pronuclear and early cleavage stages were 27\p=n-\43(35\m=.\6\m=+-\4\m=.\4)h for 2-cell stages, 36\p=n-\65 (45\m=.\7\ m=+-\ 8\m=.\3) h for 4-cell stages, 45\p=n-\73 (54\m=.\3\ m=+-\ 12\m=.\6) h for 8-cell stages and 68\p=n-\85 h for the 16-cell stage. In 7/50 patients receiving 1 or 2 embryos at the 2-, 4-and 8-cell stages, fetal development was normal and 2 women had twin pregnancies (36% success compared with 8% for single embryos). All pregnancies were from the groups in which insemination was delayed for 5\ p=n-\ 6\ m=1/ 2\ h. It is concluded that a short period of culture in vitro may allow the completion of oocyte maturation, and improve the results of in-vitro fertilization.

“…En 1979 Emecé publicó su novela que llamó "Anecdotario" en la que traduce la vastedad de sus lecturas. Él escribía en verso, en prosa, y dibujaba todo el tiempo, sin cesar y sin corregir 8 . Fue miembro fundador de la Sociedad Argentina de Diabetología, de la Sociedad Argentina de Nefrología y de la Sociedad Argentina de Investigación Clínica.…”

consolidó su interés en la especialidad de Anatomía Patológica, y donde conoció al Dr. Alfredo Lanari. Asistió entre los años 1942 y 1943 al Servicio de Patología del Johns Hopkins Hospital, bajo la dirección del brillante y afamado Dr. Arnold Rice Rich. A su regreso de Estados Unidos en 1945, fue nombrado Jefe de Anatomía Patológica del Hospital Británico, cargo que ostentaría con dedicación hasta el año 1976. Además, fue Jefe de Patología del Instituto de Investigaciones Médicas en el Hospital Tornú invitado por Lanari. Falleció repentinamente en 1980 a los 69 años, dejando una legión de amigos, de admiradores y de colegas que recordaban sus prodigiosas facultades y su ingeniosa y colorida personalidad.
