abstract background: the intracytoplasmic sperm injection procedure ending with total fertilization failure is very distressfull event for both the clinician and the patient. objective: the aim of this study was to identify independent factors which could be used to identify total fertilization failure before the day of intracytoplasmic sperm injection. materials and methods: this was a retrosp...
Protein interacting with C kinase 1 (PICK1) is a peripheral membrane protein involved in protein trafficking, a function that has been well characterized in neurons. Here, we report that male mice deficient in PICK1 are infertile and have a phenotype resembling the human disease globozoospermia. The primary defect in the testes of Pick1-knockout mice was fragmentation of acrosomes in the early ...
Background: We are convinced that better infertility treatment will only be achieved with a better under understanding of the molecular mechanisms specific to each patient. To that effect we want to indentify genes involved in male infertility. Materials and Methods: We screened cohorts of infertile men to identify the cause of their infertility. Results: Our team has identified and caracterize...
Background: Globozoospermia is an uncommon disorder of sperm morphology associated with severe male infertility. Patients who contain both normal and round-headed sperm are called partial globozoospermic. It is possible that round-headed sperm may have an abnormal chromatin structure and /or DNA strand breaks. Moreover, sperm DNA fragmentation and protamine deficiency is shown to be associated ...
