Microdose GnRH Agonist Flare-Up versus Ultrashort GnRH Agonist Combined with Fixed GnRH Antagonist in Poor Responders of Assisted Reproductive Techniques Cycles.

Background: This study compares the microdose flare-up protocol to the ultrashort gonadotropinreleasing hormone (GnRH) agonist flare combined with the fixed multidose GnRH antagonist protocol in poor responders undergoing ovarian stimulation.

Materials And Methods: In this randomized clinical trial, 120 women who were candidates for assisted reproductive techniques (ART) and had histories of one or more failed in vitro fertilization (IVF) cycles with three or fewer retrieved oocytes were prospectively randomized into two groups. Group I (60 patients) received the microdose flare-up regimen and group II (60 patients) received the ultrashort GnRH agonist combined with fixed GnRH antagonist.

Efficacy of low-dose hCG in late follicular phase in controlled ovarian stimulation using GnRH agonist protocol.

Objective: Safe, simple and cost-effective protocol is an important goal in ART cycles. The aim of this prospective study was whether administration of low-dose hCG in late follicular phase can be used clinically to replace gonadotropin administration in GnRH long protocol.

Materials And Methods: 122 patients who were candidates for ART enrolled the study and randomly divided into two groups.

Comparison of conventional IVF versus ICSI in non-male factor, normoresponder patients.

Background: Conventional IVF and ICSI are two common techniques to achieve fertilization. IVF has long been used for treatment of infertility, although it is not an effective treatment in severe male infertility. The use of ICSI has been expanded in severe male factor and fertilization failure after IVF cycle.

Effect of calcium ionophore on unfertilized oocytes after ICSI cycles.

Background: Fertilization failure is one of the most problems in assisted reproduction technology (ART).

Objective: The aim of this study was the evaluation of oocytes activation by addition of calcium ionophore in unfertilized oocytes in ICSI cycles.

Materials And Methods: This study was done on 15 ICSI cycles (stimulated with standard long protocol).

Outcome of assisted reproductive technology in women aged 40 years and older.

Background: Human fertility has been declined all over the world. Advanced women's age is one of the most important factors in determining the success of reproduction and ageing has negative impact on ART outcome and advanced female age decreases the chance of live birth rates achieved using ART, especially after 40 years of age.

Objective: To evaluate ART outcomes regarding to pregnancy, abortion, cycle cancellation and live birth rates in women 40 years and older.
