“…The cryptorchid mithun showed the decreased sperm motility & velocity and all motile spermatozoa were also nonprogressive in nature as reported in other affected domestic livestock animals (Pinart et al, 1999). Most common reason of reduced motility and velocity in cryptorchid bull are abnormal spermatogenesis and spermiogenesis, which alter the ultrastructure of sperm tail (Gopalkrishnan et al, 1995), affects the secretory activity of accessory sex glands and epididymal epithelium, which changes the biochemical structure of epididymal fluid, leads to poor development of sperm motility and velocity in the epididymal duct (Yeung et al, 1993) and vitiated (impaired) functionality of the accessory sex glands may not only produces changes in the ejaculate volume, but even changes in the semen osmolality that are responsible for alterations of motility and velocity of spermatozoa (Gopalkrishnan et al, 1995).…”

“…Percentage of infertility in unilateral cryptorchidism differed between 10 (Tellaloglus et al, 1994) to 100 % (Patkowski et al, 1992), but in bilateral, it is 100% as both testes are not functional. Studies were done on different species such as bovine for the harmful effects of cryptorchidism on seminal parameters (Marcus et al, 1997), canine (Kawakami et al, 1995), porcine (Pinart et al, 1999), equine (Ras et al, 2010), ovine (Smith et al, 2012), caprine (Igbokwe et al, 2013) and human (Mieusset et al, 1995).…”

KEYWORDS Mithun CryptorchidComputer assisted sperm analysis Motility Velocity parameters ABSTRACTThe present study was conducted to assess the motility and velocity parameters of sperm of normal intact and unilateral cryptorchid mithun bull by computer assisted sperm analyzer (CASA). Twenty ejaculates were collected from cryptorchid (n=10) and normal intact (n=10) bull. The different parameters assessed through CASA were static sperms (SM), Total Motility (TM), forward progressive motility (FPM), Average Path velocity (VAP), Average beat/cross frequency (BCF), Straightness (STR), Average straight line velocity (VSL), Average curvilinear velocity (VCL), Average amplitude of lateral head displacement (ALH), Wobble (WOB), Linearity (LIN), Elongation (EL). The result showed that these CASA parameters differed significantly (p<0.05) between the intact and cryptorchid mithun bull and intact mithun bull has significantly (p<0.05) higher value than cryptorchid mithun bulls. It was concluded that most of the CASA parameters were significantly lower in cryptorchid bulls than intact bull and however, due to the genetic hereditary nature of cryptorchid, these bulls should not be used for breeding purposes.

“…This abnormal content of sugar residues may interfere with sperm maturation during epididymal transit and also with sperm fertilizing ability (Blackmore & Eisoldt, 1999; Töpfer‐Peterson, 1999). Both abnormal testicular differentiation and defective epididymal maturation of the acrosome correlate with the increased frequency of spermatozoa with acrosomal inclusions, spermatozoa with knobbed acrosome, and spermatozoa with festooned acrosome in the ejaculate of post‐pubertal boars affected by unilateral abdominal cryptorchidism (Pinart et al ., 1998, 1999c).…”

Lectin affinity of the seminiferous epithelium in healthy and cryptorchid post‐pubertal boars

et al. 2001

The present study describes the sugar content of the seminiferous epithelium, using lectin histochemistry, in healthy boars and in boars with unilateral and bilateral abdominal cryptorchidism. In healthy boars the apical cytoplasm of Sertoli cells exhibited abundant glucosyl (Con A and WGA lectins), galactosyl (HPA, DBA, SBA and PNA lectins), and fucosyl (AAA lectin) residues. Spermatogonia and spermatocytes contained abundant glucosyl (Con A and WGA lectins) and fucosyl (AAA lectin) residues. In spermatids, galactosyl (SBA and PNA lectins) and glucosyl (Con A and WGA lectins) residues increased progressively throughout spermiogenesis, and fucosyl (AAA lectin) residues decreased. As compared with healthy boars, the scrotal testis of unilateral cryptorchid boars showed decreased amounts of fucosyl (AAA lectin) and galactosyl (HPA and DBA lectins) residues on the Sertoli cell apical cytoplasm; spermatocytes exhibited higher content of glucosyl (Con A lectin) residues and spermatids showed altered nature of glucosyl (Con A and WGA lectins) and galactosyl (SBA and PNA lectins) complexes. In abdominal testes of unilateral and bilateral cryptorchid boars, immature Sertoli cells and spermatogonia showed decreased fucosyl (AAA lectin), and increased glucosyl (Con A and WGA lectins) and galactosyl (SBA and PNA lectins) contents. These results suggest that the seminiferous epithelium of healthy boars has polarized activity with the apical compartment implicated in germ cell-Sertoli cell adhesion and interaction, in transport of ions, substrates and fluids, and in acrosomal differentiation. In scrotal testes, unilateral abdominal cryptorchidism could lead to defective germ cell-Sertoli cell adhesion, impaired acrosomal differentiation and increased ionic transport in the apical compartment of the seminiferous epithelium. Unilateral and bilateral cryptorchidism could induce increased ionic transport and membrane permeability in the seminiferous epithelium of abdominal testes.

“…Generally, ASA formation can be induced primarily during infectious and noninfectious inflammations, or by obstruction of testicular efferent duct. The incidence of ASA was also induced by an accident (Zhang et al 1990), very low temperature (Fayemi et al 1992), cryptorchism (Pinart et al 1999), vasectomy (Jessop and Ladds 1995), and by excessive male exploitation (Wicher et al 1987).…”

Blood sera from 612 bulls of different age and breed randomly selected in artificial insemination stations and bull rearing stations were examined by ELISA for the presence of antisperm antibodies. At serum dilution 1:40 and higher, the incidence of positive bulls was 35.5%. The first incidence of antibodies was recorded at the age of 5 to 6 months (13.8%), with a significant increase (58.1%; p < 0.01) at 9 to 10 months of age. In the group of bulls aged 5 months and older, positive antibody titres were detected in 42.7% of animals. The finding of antisperm antibodies was significantly higher in active donors of semen compared with the candidate breeders that have not been used as regular donors (56.4% vs. 39.2%; p < 0.01). Higher frequency of antibodies was detected in bulls of the Black Pied Holstein cattle and their crossbreeds compared with the Czech Red Pied cattle and their crossbreeds (48.4% vs. 35.2%; p < 0.01). In positive bulls with a regular semen collection, a lower ejaculate volume was found (p < 0.01) as well as lower activity of endogenous reductases in sperms (p < 0.01) and decreased sperm velocity after 120 min of heat test (p < 0.05). Fertility in those bulls was insignificantly lower. Prognostic and clinical importance of antisperm antibodies for quality assessment of breeding animals is being discussed. Cattle, testis, sperm, spermatoanalysis, autoantibodies, enzyme like immunoassay, fertilityThe development and functions of the reproductive system are controlled by complex neuroendocrine mechanisms. The immune system plays a key role under physiological conditions and in reproductive disorders. The processes leading to sperm formation have some immunologic "privileges". Sperms and their precursors exhibit quite strong antigenic traits. A wide spectrum of antigenic structures is being expressed in the testis during spermatogenesis towards which, ontogenetically, autotolerance mechanisms are inactive. Protection against autoimmunity is provided by the hemotesticular barrier composed predominantly of Sertoli cells isolating the tubular content from the vasculature, and limited lymphatic drainage of the testis. Several other immunoregulatory mechanisms also play a role, e.g. immunosuppressive factors of seminal plasma and both systemic nonspecific and specific factors (immunoregulation cells, cytokines etc.). However, the "isolation" of the sperm antigens is not complete. In the testicular interstitium the cells of the immune system are present, especially macrophages and T lymphocytes. These provide local protection against infection and some other functions, including the supply of growth factors to Leydig cells and precursors of germ cells.The formation of antisperm antibodies (ASA) and their relation to reproduction belong to so far unresolved questions in the field of reproduction. Generally, ASA formation can be induced primarily during infectious and noninfectious inflammations, or by obstruction of testicular efferent duct. The incidence of ASA was also induced by an accident (Zhang et a...
