Microsurgical fertilization and teratozoospermia

Human Reproduction, 1991
Semen 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

Teratozoospermia: spotlight on the main genetic actors in the human [PDF]

Human Reproduction Update, 2015
Male infertility affects >20 million men worldwide and represents a major health concern. Although multifactorial, male infertility has a strong genetic basis which has so far not been extensively studied. Recent studies of consanguineous families and of small cohorts of phenotypically homogeneous patients have however allowed the identification of a ...

Isolated teratozoospermia and in vitro fertilization

Journal of Assisted Reproduction and Genetics, 1996
To 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 ...

Metabolic profiling of seminal plasma from teratozoospermia patients

Journal of Pharmaceutical and Biomedical Analysis, 2020
Teratozoospermia is one of conditions that can cause male infertility. The mechanism of teratozoospermia remains unclear. The knowledge of the metabolites in human seminal plasma (HSP) is meaningful for the pathological study of teratozoospermia.

Asthenozoospermia/Teratozoospermia and Infertility

Archives of Andrology, 1990
Abnormal spermiograms with asthenozoospermia and teratozoospermia are often classified as subfertile, and the cause of these findings has been obscure. A new method, the 8-h in vitro motility profile test (MPT), showed a significant difference in motility profile between 130 fertile men and men of infertile couples.

Aneuploid spermatozoa in infertile men: Teratozoospermia

Molecular Reproduction and Development, 2002
AbstractWe 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.

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.

Isolated teratozoospermia: is there a role for antioxidant therapy?

Urologiia, 2017
Recently, 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 ...

Teratozoospermia and its effect on male fertility potential

Andrologia, 1999
Teratozoospermia and its significance for male fertility problems is discussed. Different points of view and available information concerning the phenomenon of teratozoospermia have been presented. Ongoing debate about the influence of sperm morphology on male infertility and IVF results emphasizes the fact that when sperm morphology is evaluated using
