Occurrence and functional significance of the transcriptome in bovine (Bos taurus) spermatozoa

Scientific Reports, 2017
Mammalian spermatozoa deliver various classes of RNAs to the oocyte during fertilization, and many of them may regulate fertility. The objective of the present study was to determine the composition and abundance of spermatozoal transcripts in fresh bull

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

Immunohistochemical detection of macrophage migration inhibitory factor in fetal and adult bovine epididymis: Release by the apocrine secretion mode? [PDF]

, 2006
Originally defined as a lymphokine inhibiting the random migration of macrophages, the macrophage migration inhibitory factor (MIF) is an important mediator of the host response to infection.

Methylprednisolone improves the quality of liquid preserved boar spermatozoa in vitro and reduces polymorphonuclear neutrophil chemotaxis and phagocytosis

Frontiers in Veterinary Science, 2023
After artificial insemination, immune cells such as polymorphonuclear neutrophils will be recruited into the genital tract and induce endometrial inflammation, adversely affecting the spermatozoa.

Characterization of the Olfactory Receptors Expressed in Human Spermatozoa

Frontiers in Molecular Biosciences, 2016
The detection of external cues is fundamental for human spermatozoa to locate the oocyte in the female reproductive tract. This task requires a specific chemoreceptor repertoire that is expressed on the surface of human spermatozoa, which is not fully ...

The Behavior and Acrosomal Status of Mouse Spermatozoa In Vitro, and Within the Oviduct During Fertilization after Natural Mating1

Biology of Reproduction, 2016
Although 90%–100% of mouse oocytes can be fertilized in vitro with capacitated spermatozoa within 1 h after insemination, oocytes within the oviduct are fertilized one by one over a period of several hours.

Spermatozoa: A Historical Perspective.

International journal of fertility & sterility, 2018
ABSTRACT: The 100,000th scientific article on the subject of spermatozoa was recently published. Numerous studies evaluated the characteristics of this important cell that led to tremendous discoveries. Since its first observation and description in 1677, many important characteristics have been described regarding this highly fascinating gamete.
