Abstract:

The primary organ of reproduction in the bull are the testicles. Other secondary sex organs include three accessory sex glands comprising the seminal vesicles, prostrate and bulbourethral gland (Cowper’s gland) and the reproductive male tracts. The reproductive tracts are the epididymis, the vas deferens and the penile urethra. In the male, the organs that are involved in spermatozoa production, transport and coitus are: testicles, epididymis, vas deferens or ductus deferens, prostate gland, seminal vesicles and penis. All reproductive organs work in concert for formation, maturation and trans

Abstract:

Summary Ultrasonographic images of the accessory sex glands of 8 stallions were recorded immediately prior to sexual preparation, immediately after sexual preparation, and immediately after ejaculation. Relative size changes, determined by measurements of ultrasonograms of accessory sex glands, were contrasted. Length and width of the bulbourethral glands increased significantly (P < 0.05) after sexual preparation and decreased significantly (P < 0.05) after ejaculation. The increase in bulbourethral gland volume following sexual preparation was correlated significantly (P < 0.01) wit

Abstract The accessory reproductive glands of male mammals contribute the bulk of the secretions in which spermatozoa are transported to the female tract during copulation. Despite their morphological diversity, and the chemical complexity of their products, little is known about the possible effects of sexual selection upon these glands in mammals. Here we consider the seminal vesicles and prostate glands in a sample of 89 species and 60 genera representing 8 Orders of mammals.

ABSTRACT: The effect of accessory sex gland fluid (AGF) on viability and acrosomal integrity of spermatozoa was examined with cauda epididymal spermatozoa and AGF from the same Holstein bull (n = 6). Surgical cannulation of the vasa deferentia enabled the separate collection of cauda epididymal effluent and AGF from each bull. Cauda epididymal effluent was incubated with either AGF collected from the same bull or medium alone.

Abstract:

Ejaculate comprises a range of biological substances including various proteins, acids, enzymes, carbohydrates, and trace elements that facilitate the normal functioning of spermatozoa. Any disruption in these biochemical parameters may result in diminished fertilizing capacity of sperm. The biochemical composition of ejaculate reflects the functional state of the accessory sex glands, collectively contributing to more than half of the ejaculate's volume and ensuring sperm viability. When there are changes in the primary quantitative and qualitative parameters of the ejaculate, it becomes impe

Abstract:

After spermatogenesis, testicular spermatozoa are not able to fertilize an oocyte, they must undergo sequential maturational processes. Part of these essential processes occurs during the transit of the spermatozoa through the male reproductive tract. Since the sperm become silent in terms of translation and transcription at the testicular level, all the maturational changes that take place on them are dependent on the interaction of spermatozoa with epididymal and accessory gland fluids.

ABSTRACT Introduction Worldwide 580 million males experience infertility at some point of time in their life; of these, 372 million reside in low- and middle-income countries. Male subfertility is one of the most rapidly growing fields in medicine, with dramatic advances and treatment. If a male infertility factor is present, it is almost always defined by the finding of an abnormal semen analysis, although other male factors may play a role even when the semen analysis is normal. Aims To classify the causes of male infertility at pre-testicular, testicular, and post-testicular levels. Materia

Abstract:

The aim of this work is to analyze scientific and practical data on protocols for cryopreservation of sperm of breeding goats and the effectiveness of their use. Numerous studies have established that seasonality is a characteristic reproductive function, with the greatest sexual activity observed in the autumn-winter period [1]. Goat sperm has the following species-specific features: sperm membranes contain a high level of unsaturated fatty acids, while the cytoplasm of cells, on the contrary, contains an insignificant amount of antioxidant compounds. In connection with these spermatozoa, esp

Abstract:

Abstract Seminal plasma is a complex fluid with various components (proteins, enzymes, macro-and microelements, lipids and nutrients) and its role is fundamental for spermatozoa motility, viability and fertilizing capacity maintenance. Many molecules have been measured in seminal plasma to explore some secretion functions of male accessory glands, but effects of biochemical components in human seminal plasma are still debated. Immunoglobulin-free light chains (FLCs) κ and λ are produced by plasma cells in slight excess for the need of immune response and are therefore assayable in blood and in

Abstract:

Background: Around 10 % of infertile men and 1 percent of all males have azoospermia. There are two types of azoospermia, which are obstructive and non-obstructive azoospermia. Non-obstructive azoospermia's main mechanism is because the testes fail to produce the sex hormone and induce spermatogenesis (primary testicular failure). Case: A patient is 28 years old and has a job as a car paint worker. He came with the chief complaint of infertility since two and a half years ago. He and his wife were having intercourse 3-4 times a week. Past medical history is unremarkable. His wife’s medic

Abstract:

Male accessory glands infections (MAGI) are considered one of the causes of male infertility. Chronic prostatitis is the most prevalent form of MAGI. Researches that assessed the influence of chronic prostatitis on conventional semen parameters have shown contradictory results, so the debate regarding this issue continues. Conventional semen parameters are imperfect markers of male fertility, as many men remain infertile despite being normozoospermic. The search for reliable predictors of male fertility continues to this day. Oxidative stress is considered one of the main pathogenetic mechanis

The seminal plasma is complex mixture of the secretions of the testis, epididymis and the accessory glands. The secretory proteins of the epididymal fluid as well as those of the accessory glands appear along with spermatozoa as semen at the time of ejaculation. Some of these proteins coat the sperm surface and prevent the premature activation of the spermatozoa in the female reproductive tract. The activation of spermatozoa, which requires the removal of sperm- coating proteins, is necessitated for the entry of the spermatozoa into the oocyte at the site of fertilization.

It consists of a pair of testes, each one with two follicles, one pair of seminal vesicles, two pairs of external accessory glands, and an ejaculatory bulb. The testicular follicles exhibit cysts with spermatogonia, spermatocytes, spermatids, and spermatozoa bundles. The testes are connected to the seminal vesicles by the vas deferens.

Since body weight was correlated with weights of the testes, epididymides and accessory sex glands, organ weights were adjusted for body weight in subsequent analys

Some potential markers of boar sperm freezability have been found in spermatozoa, but little attention has been paid to seminal plasma. The seminal plasma is composed of secretions from the testis, epididymis, and accessory sex glands. The exposure of spermatozoa to small molecules such as metabolites can affect sperm function. However, details and significance of the seminal plasma metabolome related to boar sperm freezability are unknown. Therefore, the main aim of this study was to explore the differences in the metabolic level of seminal plasma between boars with differential freezability
