The Anatomical Record, EarlyView.This work brings new information on the sexual characteristics of the crocodile shark (Pseudocarcharias kamoharai) exploring the pelvic fin musculature, as well as the siphon sac and the musculature and skeleton of the clasper. Our paper is the first to point out clearly the sexual dimorphism related exclusively to the pelvic fin musculature in males ...

CD33 as a leukocyte-associated marker expressed on human spermatozoa
BMC Research Notes, 2023 Objective Sialic acid-binding immunoglobulin-type lectins (Siglecs) are commonly present on immune cells and often mediate cell-to-cell interactions and signaling. Studies have shown the presence of Siglecs 1, 2, 5, 6, 10 and 14 on human spermatozoa.

Cryopreservation of Mouse Spermatozoa
Experimental Animals, 1991 The spermatozoa of cauda epididymis of mature mice were suspended in 3% skim milk in distilled water supplemented with 12, 15, 18 or 21% (W/V) raffinose. The suspension of spermatozoa were frozen in liquid nitrogen gas for 10 min, then stored in liquid nitrogen (-196 degrees C).

The Anatomical Record, EarlyView.Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

Successful ICSI in Mice Using Caput Epididymal Spermatozoa
Frontiers in Cell and Developmental Biology, 2019 Spermatozoa undergo their last phase of spermiogenesis, known as maturation, as they pass through the epididymis. A recent report indicates that mouse immature spermatozoa retrieved from the caput epididymis for intracytoplasmic sperm injection (ICSI ...

Cryopreservation of Murine Spermatozoa [PDF]
ILAR Journal, 2000 Cryopreservation of mouse sperm provides an economic option for preserving the large number of mouse strains now being generated by transgenic and targeted mutation methodologies. The ability of a spermatozoan cell to survive cryobiological preservation depends on general biophysical constraints that apply to all cells, such as the avoidance or ...

The Anatomical Record, EarlyView.Abstract Stenopodidea represents one of the basal lineages within Pleocyemata, yet the male reproductive system (MRS) of this group remains poorly understood, with limited information available regarding its morphology and function. This study provides the first detailed description of the MRS in four stenopodidean shrimp species from two families ...

The Anatomical Record, EarlyView.Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.
