Veterinary Clinics of North America: Food Animal Practice, 1995
Copulation failure in food animals can be economically devastating to producers. Many pathological conditions can result in the inability of an animal to breed. In this article, diagnosis, pathophysiology, and treatment of penile and preputial injuries and anomalies, and inguinal hernias are presented.

Obstruction of the Male Reproductive Tract
Journal of Urology, 1977Anatomic obstruction of the male reproductive ducts may be congenital, inflammatory or iatrogenic in origin. Two cases of congenital obstruction and 1 case of iatrogenic obstruction are presented. Accurate identification of the etiology and location of the obstruction is necessary for patient counseling and choice of treatment.

Pain Medications and Male Reproduction
2017The increasing use of opioid medications has become a crisis in developed countries. The profound negative effects of opioids on male reproduction are well known, but this topic is absent from the current conversations about these medications. In the fertility clinic, a significant proportion of our patients are using opioids for pain management, and ...

The aging male: impact of aging on male reproduction
BiogerontologyAging is a complex process that includes chronological aging and cellular aging. Although chronological aging is irreversible, cellular aging, which is reversible, is closely associated with chronological aging. Understanding the complexity of the impact and mechanisms of aging on the male reproductive function is crucial in maintaining male fertility.

Immunocytochemistry of Male Reproductive Organs
Archives of Andrology, 1989Immunological techniques have enabled us to see that mammalian sperm undergo complex surface changes during maturation in the male reproductive tract. Binding affinity and sperm surface binding domains have been demonstrated using immunocytochemical technique.

1986
Testes of the male bird are paired, and unlike those of most mammals are located within the body cavity, ventral and toward the cephalic border of the kidneys (Figure 19–1). Each testis is attached to the body wall by the mesorchium and is encapsulated by a fibrous inner coat, the tunica albuginea, and a thin outer layer, the tunica vaginalis.

Overview of Male Reproductive Pathology
Toxicologic Pathology, 2001An understanding of form and function is important for examination of the male reproductive tract. A basic understanding of spermatogenesis and hormonal function in the reproductive tract is essential for the pathologists in this evaluation. Gross and histologic reproductive changes need to be distinguished from normal variation and correlated with the

Vitamin D and male reproduction
Nature Reviews Endocrinology, 2014Vitamin D is a versatile signalling molecule with a well-established role in the regulation of calcium homeostasis and bone health. The spectrum of vitamin D target organs has expanded and the reproductive role of vitamin D is highlighted by expression of the vitamin D receptor (VDR) and enzymes that metabolize vitamin D in testis, male reproductive ...
