Effects of spermatozoa–oviductal cell coincubation time and oviductal cell age on spermatozoa–oviduct interactions [PDF]

open access: yesReproduction, Fertility and Development, 2013
The oviduct plays a crucial role in sperm storage, maintenance of sperm viability and sperm transport to the site of fertilisation. The aim of the present study was to investigate the effects of oviductal cell culture passage number, oviductal cell age and spermatozoa–oviduct coincubation times on gene expression in oviductal cells.

Bovine Oviductal Cannulations

open access: yesJournal of Investigative Surgery, 1988
Oviductal fluid was collected from 23 dairy cows following cannulation of the oviduct in 38 procedures utilizing silastic catheters. Standing laparotomy in the caudal abdomen enabled exteriorization of the ipsilateral ovary, oviduct, and uterine horn tip.

The morphological characteristics and modification of the oviducal glands adapted for long-term sperm storage and fertilization in Amphioctopus fangsiao

open access: yesAquaculture Reports, 2023
Sperm storage is an important reproductive strategy in Amphioctopus fangsiao. Sperm can be stored in the oviducal glands up to eight months before fertilization. However, studies on the underlying storage mechanisms remain limited.

Hens with Bilateral Oviducts [PDF]

open access: yesNature, 1957
As the reproductive organs of the female chicken develop there is an atrophy of the right gonad and the right oviduct which begins during early embryogeny. Persistency of these structures on the left side results in only one functional ovary and oviduct.

Histological findings of sperm storage in green turtle (Chelonia mydas) oviduct

open access: yesScientific Reports, 2021
Green turtles (Chelonia mydas) are seasonal breeders with a time lag between mating and nesting periods. We therefore investigated whether female turtles store sperm like some other animals by histologically and ultrastructurally analyzing oviducts ...
