A new insight into male fertility preservation for patients with completely immotile spermatozoa
Reproductive Biology and Endocrinology, 2017 Background Sperm cryopreservation is the most effective method to preserve male fertility but this is normally used for motile spermatozoa. Thus, only motile spermatozoa are used for cryopreservation in most reproductive medicine centers worldwide.

Proteasomes in human spermatozoa [PDF]
International Journal of Andrology, 2000 In the present study we describe the localization of proteasomes in human spermatozoa by means of immunolabelling with different monoclonal and polyclonal antibodies detected by confocal microscopy. Western blotting confirmed the specificity of the antibodies and has shown that proteasomes are present in spermatozoa and in seminal fluid. In spermatozoa

Structural Abnormalities of Spermatozoa in Triploid Gynogenetic Crucian Carp (Carassius auratus)
Frontiers in Genetics, 2021 The spermatozoa of triploid gynogenetic crucian carp (Carassius auratus) (3nDTCC) possess a spermatogenesis process with a normal genetic background. However, the genetic materials of these spermatozoa do not completely inherit gynogenetic progeny in ...

Redox Regulation and Oxidative Stress: The Particular Case of the Stallion Spermatozoa
Antioxidants, 2019 Redox regulation and oxidative stress have become areas of major interest in spermatology. Alteration of redox homeostasis is recognized as a significant cause of male factor infertility and is behind the damage that spermatozoa experience after freezing

The functional integrity and fate of cryopreserved ram spermatozoa in the female tract.
Journal of reproduction and fertility. Supplement, 2019 Cryopreservation advances capacitation-like changes in ram spermatozoa. These changes are reflected in an increased fertilizing ability compared with fresh spermatozoa, followed by an accelerated decline in fertilizing ability after incubation in vitro ...

Bio-Functional Sperm Parameters: Does Age Matter?
Frontiers in Endocrinology, 2020 The evaluation of biofunctional sperm parameters can explain some cases of idiopathic male infertility. Among these, sperm DNA fragmentation (fDNA) is the most studied biofunctional sperm parameter.
