The Meaning of Sperm Capacitation A Historical Perspective [PDF]

Journal of Andrology, 1984
It should be recalled that sperm capacitation was originally defined in 1952 as some physiological changes of the spermatozoa in the female genital tract before they are capable of penetrating and fertilizing the eggs. It was found further that capacitation can be achieved outside the female tract, first in the presence of biological fluids, and then ...

A Low Concentration of a Sustainably Obtained Blueberry Extract Improves the Post‐Thawing Motility of Cryopreserved Bull Spermatozoa

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Natural extracts could improve sperm storage and artificial insemination (AI). This study, for the first time, evaluates the suitability of a blueberry extract (Vaccinium corymbosum), obtained from pomace using a sustainable methodology, as a supplement for bull semen extenders.

Sperm Recovery and Evaluation in Domestic Species: Challenges and Current Practices

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Semen collection is a key step in the development of assisted reproductive technologies (ARTs) in domestic mammals, as the collection method determines the functionality and fertility of the sperm. The artificial vagina or manual collection yields ejaculates similar to those obtained during natural mating, although they require prior training ...

Paternal SIRT1 Inhibition During Capacitation Imprints Histone 4 Hyperacetylation in Mouse Zygotes and Blastocysts

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Sirtuin 1 (SIRT1) is a NAD+‐dependent deacetylase involved in chromatin remodelling. In this study, we evaluated whether sperm SIRT1 inhibition affects early embryonic chromatin dynamics. Sperm were treated with sirtinol during capacitation or during both capacitation and fertilization. SIRT1 inhibition increased acH4K16 in the male pronucleus

Estrous Sheep Serum‐Derived Extracellular Vesicles Deliver Proteins That Modulate Sperm Motility in Sheep

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Sperm capacitation requires signals from the female reproductive environment, although the molecular mechanisms governing this process remain poorly understood. Estrous sheep serum (ESS) is widely used in in vitro fertilization of small ruminants, contributing to mimic the female reproductive fluids.

Molecular Pathways Involved in Stallion Sperm Capacitation

After ejaculation, mammalian spermatozoa must undergo a series of complex and poorly understood cellular events known as “capacitation” in order to be able to fertilize an oocyte.

RESEARCH CONCERNING THE INFLUENCE OF CAPACITATION CONDITIONS ON THE QUALITY OF SPERMATOZOA USED FOR IN VITRO FERTILIZATION

Scientific Papers Animal Science and Biotechnologies, 2023
The optimization of capacitation technique is based on the study of the influence factors of this process. Studying the influence of capacitation conditions on boar sperm quality we concentrated our research upon capacitation technique and method.

Effect of Different Equilibration Times in the Freezing Process on Post‐Thaw Motility Parameters in Equine Spermatozoa

Reproduction in Domestic Animals, Volume 61, Issue 10, October 2026.
ABSTRACT Cryopreservation of stallion semen remains suboptimal, with approximately one‐third of stallions producing semen that is poorly tolerant to freezing. As optimization of pre‐freezing procedures may improve post‐thaw sperm quality, this study evaluated the effect of different equilibration times before freezing on the post‐thaw quality of ...

A Fluorometric Method for Measurement of Sperm Capacitation

Experimental Biology and Medicine, 1967
SummaryA fluorometric technique for measurement of sperm capacitation is described. Rabbit sperm were labeled with tetracycline HCI (T-HCI) and placed in uteri and oviducts of estrous and pseudopregnant does and in other regions of estrous females.
