The effects of the human oocyte vestments and follicular fluid on spermatozoa [PDF]

, 2012
Our knowledge of the released human ovulatory components, the cumulus-oocyte complex (COC) and follicular fluid, and their physiological effects on spermatozoa and roles in fertilisation remain poorly characterised.

Increased frequency of aneuploidy in long-lived spermatozoa. [PDF]

PLoS ONE, 2014
Aneuploidy commonly causes spontaneous abortions, stillbirths, and aneuploid births in humans. Notably, the majority of sex chromosome aneuploidies in live births have a paternal origin.

MOTILITY OF SPERMATOZOA [PDF]

Journal of the American Medical Association, 1917
To the Editor: —In the Current Comment on "The Function of the Prostate" (The Journal, Feb. 17, 1917, p. 553), it is stated that "it has been noted that the spermatozoa are practically motionless while in the seminiferous tubules of the testis, but become actively motile in the vas deferens, or when mixed with prostatic secretion." The statement that

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.

Expression of Tas1 taste receptors in mammalian spermatozoa [PDF]

, 2012
Background: During their transit through the female genital tract, sperm have to recognize and discriminate numerous chemical compounds. However, our current knowledge of the molecular identity of appropriate chemosensory receptor proteins in sperm is ...

CaMKIIalpha interacts with multi-PDZ domain protein MUPP1 in spermatozoa and prevents spontaneous acrosomal exocytosis [PDF]

, 2009
The success of acrosomal exocytosis, a complex process with a variety of inter-related steps, relies on the coordinated interaction of participating signaling molecules.

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 ...
