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.
