Increased demands of the seafood market have led to rapid growth in crustacean aquaculture production various parts world. Therefore, an expansion knowledge reproductive biology crustaceans has become more important. Hormones released from androgenic gland (AG) are liable for both separation primary and secondary sexual features behavior. AG removal male causes a transformation intersex animals...

Discussion of the problem of anabolic-androgenic steroid abuse has been generally limited to the context of professional sports and major international sporting events such as the Olympics. Anabolic-androgenic steroid abuse is not, however, limited to professional and 61ite athletes, nor to athletes only, but it has now spread to amateur and lower level athletes as well as to the general public...

Dimorphism on dominance and agonistic behaviour in mammals tends to be strongly biased toward males. In this review, we focus on a select few species of mammals in which females are as or more aggressive than males, and/or are dominant to males, and explore the role of androgenic hormones in mediating this important difference. While the data are not as clear-cut as those published on tradition...

Androgen insensitivity syndrome (AIS) is a condition that results in the partial or complete inability of the cell to respond to androgens (androgenic hormones) that stimulate or control the development and maintenance of male physiological characteristics by binding to androgen receptors. The unresponsiveness of the cell to the presence of androgenic hormones can impair, or prevent, both the m...

YOUTHEN is a polyherbal formulation. The present was designed to establish the effect of YOUTHEN on androgenic and reproductive parameters of male albino rats. YOUTHEN at lower dose stimulated the haemopoietic function significantly. Higher dose of YOUTHEN significantly enhanced the sperm count, forward motility index and metabolic activity of tech spermatozoa of the experimental animals as com...

Ultraviolet solar radiation is a well-known environmental health risk factor and the use of sun lotions is encouraged to achieve protection mainly from skin cancer. Sun lotions are cosmetic commercial products that combine active and inactive ingredients and many of these are associated with health problems, including allergic reactions and endocrine disorders. This review focuses on their abil...

To study the effect of calcium ion on aromatization of an androgenic precursor to estradiol by the placenta, cultured term trophoblasts were used as a model system. Secretion of estradiol into the culture medium was regarded as indicating aromatization, since cells cultured with no androgenic precursors produced only insignificant amounts of estradiol. EGTA, verapamil and ionophore A23187 inhib...

The abundant adrenal C19 steroid 11β-hydroxyandrostenedione (11OHA4) has been written off as a dead-end product of adrenal steroidogenesis. However, recent evidence has demonstrated that 11OHA4 is the precursor to the potent androgenic 11-oxygenated steroids, 11-ketotestosterone and 11-ketodihydrotestosterone, that bind and activate the human androgen receptor similarly to testosterone and DHT....

BACKGROUND Anabolic steroids have the clinical effect of increasing protein synthesis in muscle and other tissues. The brain and spinal cord neurons have gonadal steroid receptors and various studies have shown at structural and molecular levels that androgenic steroids have a significant trophic effect on the brain and spinal cord. CASE REPORT We evaluated the effect of Oxandrolone (an FDA-a...
