ABSTRACT
Parto P, Vaissi S, Farassat H, Sharifi M., Reproductive
morphology and sperm storage in Neurergus kaiseri (Caudata: Salamandridae), Onl
J Vet Res., 19(9):
587-592, 2015. Sperm storage in cloacal spermathecae was determined in
female Neurergus kaiseri salamander during the breeding season.
Individuals stored sperm within spermathecal ultrastuctures. The spermathecae
exhibited characteristics of secretory epithelium with irregular nuclei
surrounded by thin cytoplasm and without organelles involved in synthetic
activities. Within spermathecal tubules filled with secretory material,
relatively small groups of sperm are aligned along their entire lengths in parallel
arrays. Some spermatozoa are embedded in the secretory matrix or invaded deeper
into the spermathecal epithelium. Considering
the onset of courtship behavior in early December, and oviposition of first
eggs in late February, we propose that sperm storage in N. kaiseri lasts
1.5-2 months.
Keywords caudata, Neurergus
kaiseri, sperm storage.
