Molecular genetic mechanisms of teratozoospermia
Zygote, 2023SummaryIn recent years, the incidence of teratospermia has been increasing, and it has become a very important factor leading to male infertility. The research on the molecular mechanism of teratospermia is also progressing rapidly. This article briefly summarizes the clinical incidence of teratozoospermia, and makes a retrospective summary of related ...

O-176 Genetics of teratozoospermia
Human ReproductionAbstract Male infertility, affecting over 20 million men worldwide, is a significant health concern with a strong yet underexplored genetic basis. Recent advances in genetic sequencing, particularly the use of whole-exome sequencing (WES), have enabled the identification of many genetic causes of teratozoospermia, including AURKC ...

Microsurgical fertilization and teratozoospermia
Human Reproduction, 1991Semen parameters were correlated with the outcome of partial zona dissection (PZD) in 42 couples with male factor infertility. Although fertilization rates were reduced, 12% of the embryos implanted following replacement. Spermatozoa from teratozoospermic sperm populations were able to fuse with oocytes following zona penetration through the artificial

Isolated teratozoospermia and in vitro fertilization
Journal of Assisted Reproduction and Genetics, 1996To show whether increased amounts of spermatozoa used in insemination of preovulatory oocytes in isolated teratozoospermia according to Kruger's strict criteria gives good fertilization rates.This study was carried out from September 1993 to November 1994 for a total of 77 cycles, with sperm samples classified according to Kruger's strict ...

Aneuploid spermatozoa in infertile men: Teratozoospermia
Molecular Reproduction and Development, 2002AbstractWe and others have demonstrated that infertile men who are candidates for intracytoplasmic sperm injection (ICSI) have an increased frequency of chromosomal abnormalities in their sperm. Reports based on prenatal diagnosis of ICSI pregnancies have confirmed the increased frequency of chromosomal abnormalities in offspring.

Isolated teratozoospermia: is there a role for antioxidant therapy?
Urologiia, 2017Recently, literature has emerged that offers contradictory findings of idiopathic forms of isolated teratozoospermia that may confuse clinicians. Some researchers argue that at 0-1% of normal forms of spermatozoa, morphology itself cannot be a prognostic indicator of fertility, either in the planning of natural pregnancy, or when used in assisted ...

Results of Varicocelectomy in Patients with Isolated Teratozoospermia
Urologia Internationalis, 2008<i>Introduction:</i> Isolated teratozoospermia is rarely encountered in patients with clinically palpable varicocele, and the consequences of varicocelectomy remain unclear in these cases. In the current study, we assessed the effect of varicocelectomy on sperm morphology in a series of patients with infertility.
