Despite the advent of ICSI, cases of total fertilization failure (TFF) often lead to cycle cancellation with limited diagnostic and therapeutic strategies currently available. We report on the case of an infertile couple who failed to conceive after repeated IVF and ICSI. Sperm of the husband were morphologically normal and passed a functional test assessing their ability to activate mouse oocy...

BACKGROUND Recently, motile sperm organelle morphology examination (MSOME) criteria as a new real time tool for evaluation of spermatozoa in intracytoplasmic sperm injection (ICSI) cycles has been considered. OBJECTIVE The aim was to investigate the predictive value of MSOME in in vitro fertilization (IVF) in comparison to ICSI cycles and evaluation of the association between MSOME parameters...

Intracytoplasmic sperm injection (ICSI) is the method of choice for fertilizing horse oocytes in vitro. Nevertheless, for reasons that are not yet clear, embryo development rates are low. The aims of this study were to examine cytoskeletal and chromatin reorganization in horse oocytes fertilized by ICSI or activated parthenogenetically. Additional oocytes were injected with a sperm labeled with...

background: in vitro fertilization (ivf) and intra cytoplasmic sperm injection (icsi) are recognized as established and increasingly successful forms of treatment for infertility, yet significant numbers of couples discontinue treatment without achieving a live birth. this study aims to identify major factors that influence the decision to discontinue ivf/icsi treatments. materials and methods:...

Background: Our Background was to evaluate the effect of ovarian endometrioma on ovarian stimulation outcomes in Intra Cytoplasmic Sperm Injection (ICSI). Materials and Methods: In this prospective cohort study, we followed 103 patients underwent ICSI procedures at royan Institute during 10 month. The study group consisted of 46 women who had endometriomawith size more than 1 cm. The control gr...

The non-hormonal contraceptive, named RISUG (an acronym for Reversible Inhibition of Sperm under Guidance) has expected to provide a valuable addition to the current options of male contraception. The present study was conducted to determine the reproductive functional success, safety of vas occlusion by RISUG, and its reversal by dimethylsulphoxide (DMSO), followed by multigenerational (F1-F3)...
