Evaluation of morphological criteria of sperm quality before in vitro fertilization and intracytoplasmic sperm injection.

O-32: Effects of Intrauterine Injection of Recombinant Human Chorionic Gonadotropin before Embryo Transfer on Outcome of In Vitro Fertilization/Intracytoplasmic Sperm Injection: A Randomized Clinical Trial

Background: To evaluate the effectiveness of intrauterine injection of recombinant human chorionic gonadotropin (rhCG) before embryo transfer (ET). Materials and Methods: In this randomized placebocontrolled clinical trial, a total number of 182 infertile patients undergoing their first in vitro fertilization/intracytoplasmic sperm injection (IVF-ICSI) were randomly assigned to receive 250 μg i...

Relationship between Endometrial Thickness and In Vitro Fertilization-Intracytoplasmic Sperm Injection Outcome

P-41: Evaluation of CAPZA3 Expression in Infertile Individuals Undergoing Intracytoplasmic Sperm Injection

Background: CAPZA3 is one of the actin-capping proteins believed to be play an important role in controlling of actin polymerization during spermiogenesis and has been shown to be peresent in mature sperm. Immunohistochemistry showed that human CAPZA3 is localized in the neck region of ejaculated sperm, with moderate and faint signals also detected in the tail and post-acrosome region respectiv...

The evaluation of sperm chromatin status in men with different infertility factors, and its relationship with ICSI outcomes

One of the most important factors related to male fertility is sperm chromatin status. Under Assisted Reproductive Techniques (ART), especially Intracytoplasmic Sperm Injection (ICSI), the natural selection of high quality sperm with intact chromatin is not possible. Therefore, embryo quality and pregnancy rate decreased for damaged DNA of sperms involved in the fertilization of eggs. Thus, thi...

The First Report of Successfully Pregnancy after ICSI with Combined DGC/Zeta Sperm Selection Procedure in a Couple with Eleven Repeated Fail IVF/ICSI Cycles

This is the first report implementing combined density gradient centrifugation/Zeta (DGC/Zeta) sperm selection procedure for a couple with eleven previous intra cytoplasmic sperm injection/ in vitro fertilization (ICSI/IVF) failure cycles. Semen analysis was carried out according to World Health Organization criteria. Protamine deficiency, DNA fragmentation and morphology were assessed by chrom...
