2013; Reinhard, 1956), reduction in circulating reproductive hormones (Robert, 1997; Lafferty and Kuris, 2009; Walker, 1977), indirect hormonal castration (Hechinger, 2010; Baudoin, 1975) or in male host, decline of secretion by the androgenic gland
We tested the hypothesis of androgenic gland persistence in FPSHs of L.
Although relative androgenic gland size appears to differ little between the two sexual morphs, there is a distinct difference in their overall aspect and internal structure.
However, in smaller MPs, AGs are compact and replete with androgenic gland cells, similar to sexually active MPs in the protandric species Pandalus platyceros (AG stages 2-3; Hoffman, 1969).
Furthermore, techniques used in confirming, measuring, and silencing expression and activity of the insulin-like peptide of the androgenic gland (IAG)--like those used in studies of the gonochoric shrimp Macrobrachium rosenbergii (Ventura et al.
Apparently, the feminization of genetic males by Wolbachia is due to an inhibition of androgenic gland
Intersex individuals may represent cases of true hermaphroditism, in which the androgenic gland disappears to permit the expression of the feminine phase in protandric species (Charniaux-Cotton, 1958).
An androgenic gland was attached to the subterminal region of each sperm duct.
quadricarinatus individuals that have a male genital opening also have a testis, a sperm duct, and an androgenic gland on that side [ILLUSTRATION FOR FIGURE 3 OMITTED].
In male crustaceans, in addition to the two neurohormones, GSH and GIH, the androgenic gland hormone (AGH) has a major role in the control of spermatogenesis.
The diameters ([mu]m) of 50 cells in each androgenic gland were likewise measured.
Effects of DA, DA antagonists, 5-HT alone, and 5-HT in combination with DA on the androgenic gland
