| Popis: | The present report examines the composition of luminal fluid in the seminiferous tubule (STF), rete testis (RTF), and ductus epididymidis of the Japanese quail (Coturnix coturnix japonica). This subject is of particular interest, both because the reproductive ducts are intra-abdominal and because sperm production is more rapid in birds than in mammals. It was interpreted that micropuncture samples of STF contain varying amounts of contamination with intracellular solute, particularly K and protein. The concentration of solute in samples was correlated with packed cell volume (spermatocrit), and when the latter was used to assess estimates of solute concentration in STF, the magnitude of the estimates were much the same as determinations in RTF. Consequently, it is concluded that the fluid entering the rete testis of the quail is the primary secretion of the seminiferous tubules. The composition of RTF in the quail was determined to be 148 mM Na, 126 mM Cl, 9.8 mM K, 2.7 mM Mg, 1.4 mM Ca, 2.1 mM g... |
