Male Accessory Sex Glands

The accessory sex glands of the male reproductive tract include the prostate, seminal vesicles, and bulbourethral glands. These are highly androgen-dependent tissues that function primarily to produce the seminal fluids that compose semen. As in the [Pg.820]

Cimetidine (for treatment of peptic ulcers) competes with dihydrotestosterone for receptors in the testis and accessory sex glands. The more common sequelae are low sperm count and gynacomastia. Epidemiological evidence has shown that occupation exposure to oral contraceptives can induce gynacomastia in exposed males. Diethylstilbestrol (DES) antagonizes the activity of fetal testosterone. In the male offspring, testicular hypoplasia, abnormal semen parameters, and infertility result. Ketoconazole has be shown to be transported to the seminal fluid and to immobilize the sperm. [Pg.345]

The male reproductive tract consists of the (i) testes, which serve as the site of gamete and steroid hormone production, (ii) excurrant ducts and epididymes for the transport, maturation, and storage of sperm, (iii) accessory sex glands for the production of seminal fluid, and (iv) penis, for copulation and delivery of mature sperm to the female reproductive tract. [Pg.813]

Adult N. lapillus were tested for 3 months in the laboratory in a nominal concentration range between 1 and 100 pg BPA. Super females in the dog whelk were also characterized by enlarged accessory pallial sex glands and an enhancement of egg production, but the test compound also affected the males in this species. A lower percentage of exposed specimens had ripe sperm stored in their vesicula seminalis, and male Nucella exhibited a reduced length of penis and prostate gland when compared to controls. [Pg.246]

Reproductive Behavior. Male accessory glands contain peptides which affect female reproductive behavior. Female sexual receptivity is diminished after mating (22) and oviposition is stimulated (22). Peptides responsible for these behaviors have been isolated from Drosophila species (22,23) and sequenced. In addition, a peptide with similar behavioral influences in a lepidopteran has been isolated from Helicoverpa zea (24). Miller (this volume) discusses the potential of these "sex peptides" in the development of unique insect control strategies. While males influence female reproductive behavior via the action of "sex peptides", females, especially in the Lepidop-tera, influence male behavior through the release of pheromone. The production of pheromone, in turn, is controlled by the pheromone biosynthesis activating neuropeptide (PBAN for a comprehensive review see 25). PBAN-like activity has been observed in more than 20 insect species (25) and offers another avenue for exploitation of neuropeptides in insect control. [Pg.184]
