ABSTRACT

PURPOSE: To compare the efficiency of transvaginal ultrasound-guided functional ovarian cyst aspiration, with conservative management, in the outcome of patients undergoing assisted reproductive technique (ART) (in vitro fertilization or intracytoplasmic sperm injection). These cysts were identified before ovarian stimulation begun and after administration of a midluteal GnRH agonist. METHODS: Fifty nine patients undergoing ART from January 1, 1997 to February 28, 1999, who developed functional ovarian cysts were included. Aspirations of these cysts (n = 14) versus conservative management (observation) (n = 45) were compared. Total number of ovarian follicles developed, number of oocytes retrieved, estradiol levels on the day of human chorionic gonadotropin, fertilization rate, number of good quality embryos transferred, implantation, and clinical pregnancy rate per cycle were evaluated. RESULTS: No statistical differences were observed between the two groups in any of the selected parameters. CONCLUSIONS: Cyst aspiration and conservative management showed similar implantation and pregnancy rates, in patients who develop functional ovarian cysts after pituitary down-regulation following luteal phase gonadotropin-releasing hormone agonist administration. Prospective studies are needed to confirm this trend.

ABSTRACT

OBJECTIVE: To reassess endometrial morphological criteria of normality identifying the best morphological and molecular "implantation window" indicators in normal women. DESIGN: Prospective clinical study. SETTING: Assisted reproductive unit. PATIENT(S): Fourteen healthy volunteers. INTERVENTION(S): Blood sampling for LH, E(2), and progesterone (P4) determinations. Daily vaginal ultrasounds. Two endometrial biopsies per volunteer, 7 days apart, during luteal phase. MAIN OUTCOME MEASURE(S): Endometrial dating, pinopodes formation, immunohistochemical determination of integrins (alphavbeta3, alpha4beta1), leukemia inhibitory factor (LIF), interleukin-1 receptor type I (IL-1R tI), mouse ascites Golgi (MAG), the transmembrane mucin (MUC-1), and P4 receptor expression. RESULT(S): In 26 of 28 biopsies observers agreed; in two biopsies there was a discrepancy (difference of 72 hours). With use of LH peak, 24 of 26 samples were in phase, and 2 were 3 days behind. Pinopodes appeared on days 20-21 and persisted through day 28 in small groups or larger areas. beta3 Integrin was highly expressed in luminal and glandular epithelium from day 22 through 28; 48 hours thereafter pinopodes appeared. alpha4 Subunit exhibited luminal epithelium reaction positivity on days 22-23 and glands on days 18-23. LIF and IL-1R tI showed weak, erratic expression. MAG antibodies showed luminal epithelium expression up to day 22 and glands up to day 25. MUC-1 showed positivity during the whole luteal phase. P4 receptors were positive through day 20 and at the end of the luteal phase. CONCLUSION(S): The three most cited markers that frame the window of implantation do not correlate in our material. Pinopodes are present from day 20 on; beta3 and alpha4 integrin subunits indicate a window opening on days 22-23.

ABSTRACT

OBJECTIVE: To report the birth of healthy twin males after the use of testicular spermatozoa from a nonmosaic patient with Klinefelter's syndrome. DESIGN: Case report. SETTING: Private reproduction center with university affiliation. PATIENT(S): A couple undergoing intracytoplasmic sperm injection (ICSI) combined with testicular sperm extraction because of the husband's secretory azoospermia and a nonmosaic 47,XXY peripheral blood karyotype. The wife, a healthy female, presented with a history of oligomenorrhea. INTERVENTION(S): ICSI was performed using testicular spermatozoa; 3 mM pentoxifylline solution was used to induce sperm motility because the spermatozoa recovered were all immotile. MAIN OUTCOME MEASURE(S): Normal fertilization, embryo cleavage, pregnancy outcome, and peripheral blood karyotype of the newborns. RESULT(S): Thirteen metaphase II oocytes were injected. Seven of them fertilized normally and six did not fertilize. Three good-quality embryos (4-cell stage class II) were transferred, and four were cryopreserved at the two-cell and four-cell stages using a slow freezing protocol. Twelve days after ET, a beta-hCG determination was positive. Ultrasonographic examination revealed three intrauterine fetal sacs, but one of them showed a fetal pole without cardiac activity and vanished in subsequent ultrasonographic examinations. The patient delivered twins with normal male peripheral blood karyotypes. CONCLUSION(S): Normal outcome after the use of testicular sperm extraction and ICSI in a nonmosaic patient with Klinefelter's syndrome reaffirms the notion of low transmission risk of this gonosomal aneuploidy.

ABSTRACT

Introducción: la estimulación de ovulación para el desarrollo de múltiples folículos, es un requisito fundamental para obtener éxito en un programa de fertilización asistida (FA). De estos folículos, se obtienen una cantidad aceptable de óvulos y embriones que posibilite una buena tasa de implantación y embarazo. Los esquemas más comúnmente utilizados para la hiperestimulación ovárica controlada son, en la actualidad, la combinación de análogos de Gn-RH y gonadotrofinas. La gonadotrofina cariónica humana (hCG), es usada como reemplazo del pico de LH, con el fin de producir la maduración final de los ovocitos, previo a la aspiración folicular. El término de Síndrome de Folículo Vacío (SFV), fue descripto por Coulam y col., quienes fueron además, los primeros en reportar, en ciclos de la FA la ausencia de óvulos, luego de una aspitación folicular, a pesar de valores de estradiol y tamaño folicular aceptable. Objetivos: Mostrar la experiencia del CEGYR, con el Síndrome de Folículo Vacío en FA durante un período de un año. Material y Métodos: Del 1º de Junio de 1994 hasta el 31 de Mayo de 1995, se realizaron en el CEGYR 274 casos de FA. En casi todos los casos se utilizó para la estimulación de ovulación, análogos de Gn-RH y gonadotrofinas en diversos esquemas. La monitorización de la ovulación, la aplicación de la hCG y la aspiración ovocitaria, se realizaron de acuerdo a criterios habituales. El procedimiento de aspiración se realizó siempre por profesionales entrenados. Se definió síndrome de folículo vacío cuando no se obtuvieron óvulos a pesar de una respuesta ecográfica y bioquímica normal a la estimulación de la ovulación. Resultados: De los 274 casos de FA que se realizaron en un período de un año en el CEGYR, se observaron 5 casos de Síndrome de Folículo Vacío,...
