[Embryonic quality in the use of urofolitropin vs recombinant FSH for in vitro fertilization]. / Calidad embrionaria en la utilización de urofolitropina vs FSH recombinante para fertilización in vitro.

There were no differences in both groups as tho the age of the patients; received doses of both types of FSH, nor HMG; but there was as to the amount of captured ovocytes, amount, and quality, embrionary, in special 1+ 2+ in favor of the group that received urofolitropine, specially under 35 years of age. In this study there was better qualy and amount, embrionary, obtained with the use of urofolitropine, as compared with FSH recombinant for in vitro fertilization.

Comparación de dos técnicas de inseminación artificial. (Perfusión tubárica de esperma e inseminación intrauterina) / Comparison of two artificial insemination techniques-Sperm tubal perfusion and intrauterine insemination

En 1991 Kahn y col. describieron un método de inseminación intrauterina llamado Perfusión Tubárica de Esperma (PTE) utilizando un volumen inseminado de 4.0 ml, a diferencia de la Inseminación Intrauterina (IIU) clásica en la que el volumen inseminado es de 0.5 ml. El objetivo del estudio es comparar la tasa de embarazos de ambas técnicas. Durante un período comprendido entre agosto de 1993 a enero de 1994 se atendieron 60 pacientes con infertilidad se realizaron 131 ciclos de inducción de ovulación e inseminación intrauterina, 95 fueron con IIU y 36 con PTE. Se obtuvieron 18 embarazos clínicos, 11 con IIU y 7 con PTE, representando una tasa de éxito de 11.5 por ciento para la primera y de 19.4 por ciento para la segunda técnica. Estos resultados confirman los obtenidos por Kahn. La PTE representa una nueva posibilidad para el tratamiento de la infertilidad de diversas etiologías

[Retroperitoneal teratoma associated with primary neoplasm of the ovary. Presentation of a case]. / Teratoma retroperitoneal asociado a primario de ovario. Presentación de un caso.

The retroperitoneal teratomas are rare neoplasias that represent only 3.5% of all extragonadal teratomas. They generally appear in the first decade of life, and the incidence in adults is rare. We describe a rare case of extragodonal teratoma, not only because the patient is in the 7th decade of life, but also because of the localization and association of two epithelial cellular tumors of the ovary. We also describe the surgical and histopathological findings as well as an analysis of the frequence, clinical characteristics, diagnosis and treatment for this neoplasia.
