“…The early research found the proper trigger-OPU interval in patients stimulated with clomiphene citrate (CC) or hMG was 32-36 h [2,29,30]. After that, lots of research explored whether oocytes should be retrieved earlier or later in the gonadotropin-releasing hormone analog (GnRHa) combined with hMG protocol [1,5,9,13,14,31,32]. For the different GnRHa protocols which may bring the distinct extent of pituitary suppression and need diverse in vivo maturation time before oocyte retrieving, the only related research is one meeting abstract [16], which found the long protocol, flare-up, and antagonist protocols had their discrepant optimal time for oocyte retrieval in terms of egg maturation, fertilization, implantation, and clinical pregnancy rates.…”

“…The clinical results of ART vary along with the time interval between oocyte maturation trigger and aspiration. Some studies have found that longer OPU time did not lead to more mature oocytes or better clinical results [4][5][6][7][8], whereas other studies have found that longer OPU time may produce more mature oocytes [1,9,10], higher fertilization rate [11], better blastocyst development [12], more goodquality embryos, and higher ongoing pregnant rate [13]. There were also some studies which showed prolonging the interval between human chorionic gonadotropin (hCG) priming and oocyte retrieval could only increase the proportion of MII oocytes, rather than the pregnancy rates [14,15].…”

Purpose To explore the trends of oocyte and pregnancy outcomes over the ovulation trigger-OPU (oocyte pickup) time interval in four mainly used COH protocols. Methods This retrospective study was conducted between January 2013 and July 2018. The IVF/ICSI cycles of the patients with normal ovarian reserve were included. The number of total patients was 4673, which consisted of long agonist protocol (n = 819), short agonist protocol (n = 1703), mild stimulation protocol (n = 1627), and GnRH antagonist protocol (n = 524). The primary outcome was mature oocyte rate. Results The ovulation trigger-OPU time interval and COH protocol were related to cycles with > 80% MII oocytes. Four protocols showed apparently different trends of retrieved oocyte rate and mature oocyte rate over the ovulation trigger-OPU time interval, and the long agonist protocol had the most delayed time interval than other three COH protocols in retrieving more than 60% oocytes (35.

“…La IIU forma parte de las estrategias de manejo inicial en parejas con infertilidad, y diversos investigadores demuestran tasas aceptables de embarazo para este procedimiento. Farquhar y col. observaron una TEC de 31% con IIU, en comparación al 9% de una evolución espontánea, sin tratamiento (5) , y Bensdorp y col. encontraron que la IIU asociada a estimulación ovárica, la FIV asociada a transferencia de embrión único y la FIV en ciclo natural modificado tuvieron éxito similar (tasas de nacido vivo de 47%, 52% y 43%, respectivamente) (6) .…”

Introducción. La inseminación intrauterina es parte de las estrategias del manejo inicial en parejas con infertilidad. Su efectividad en la búsqueda de embarazo ha sido poco investigada y conocida en nuestro país, por lo que es importante definir los grupos de pacientes, indicaciones y condiciones asociadas a una mayor tasa de embarazo clínico. Objetivo. Definir los factores asociados a embarazo clínico en la inseminación intrauterina. Métodos. Estudio retrospectivo de 633 parejas con diagnóstico de infertilidad atendidas en el Centro de Fertilidad y Ginecología del Sur, Cusco, Perú. Se realizaron 1 053 ciclos de inseminación intrauterina, en ciclos espontáneos o asociados a estimulación ovárica, con inseminación doble o simple, inseminación pre o post ovulatoria, con muestra de semen del cónyuge capacitada por swim-up o por gradientes de densidad. Resultados. La tasa de embarazo clínico fue 8,2% por ciclo de inseminación y 13,6% por pareja. Los factores con mayor asociación al embarazo clínico fueron: contar con 2 folículos o más (OR: 2,873), lograr la inseminación sin dificultad (OR: 2,341), tener 3 años o menos de infertilidad (OR: 2,240), el factor cervical como indicación (OR: 2,194), uso de gonadotropinas (OR: 1,846) y edad de la mujer menor a 38 años (OR: 1,819). Conclusiones. La inseminación intrauterina logró una tasa de embarazo clínico aceptable en nuestro estudio, requiriendo ser acompañada de una adecuada selección y preparación de las parejas.
