ABSTRACT
Parto
P, Vaissi S, Farassat H, Sharifi M., Changes in ultrastructure of stored sperm in cloaca of female
salamander Neurergus kaiseri, Onl J
Vet Res., (10): 742-746, 2022. Sperm
storage in cloacal spermathecae was studied in female Neurergus kaiseri
during breeding. Individuals stored sperm within spermathecal ultrastuctures. The spermathecae exhibited characteristics of secretory
epithelium with irregular nuclei surrounded by thin cytoplasm without
organelles involved in synthetic activities. Within spermathecal tubules filled
with secretory material, relatively small groups of sperm were aligned along
their entire lengths in parallel arrays. Some spermatozoa were 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 infer that sperm storage in N.
kaiseri lasts for 1.5-2 months. Images are provided to support findings.
Keywords: caudata, Neurergus kaiseri, sperm storage.
