“…The macro and microscopic aspects of the uterus were in agreement with the general avian descriptions. The morphology and histochemistry of the epithelium of the uterine mucosa were also in agreement with the previous citations for quails (Moraes et al, 2007;Moraes et al, 2009). The uterus of quails is similar to that of laying hens, except for the dark-brown coloration of the mucosa, as described by Artoni et al (2001).…”

This study described changes in the serum biochemistry, morphology of genital organs, long bone, and eggshell during the daily egg formation cycle in Japanese quails. Sixty quails (18-wk) were distributed in 6 groups according to hours post-oviposition (POV): 0 hr POV (16h00), 2 hrs POV (egg in magnum), and 4, 8, 14, and 20 hrs POV (egg in uterus). The magnum had higher relative weight before the next ovulation (20 and 0 hr POV), and its tubular glands showed functional variation through periods: abundant eosinophilic, PAS+, and negative Alcian blue secretion at 0 and 2 hrs, empty glands aspect at 4 hrs, and filled again at 20 hrs POV. Serum albumin and total Ca had the highest value in the 2 hrs group, and the lowest in 8 and 14 hrs groups. Egg-cycle period affected the Ca% of the medullar bone of the femur and tibiotarsus, with the lowest mean at 14 hrs POV (06h00), and the highest mean after oviposition (0 hr POV), showing the recovery of Ca stores in long bones for the next egg cycle. Analysis of the eggshell using scanning electron microscopy evidenced that palisade layer formation starts during the night (8-14 hrs POV), and most parts are secreted during the day period. In conclusion, eggshell secretion in light periods, high magnum activity and medullary bone Ca deposition during midday and afternoon, as well as the ovulation/oviposition in the afternoon, are the main characteristics of the distinct physiological aspects of the egg cycle in quails.

“…As GHEs e as GIs encontravamse distribuídas ao longo das pregas da junção uterovaginal e do infundíbulo distal, em arranjo desordenado ( Fig. 1A e D), semelhantemente às descrições realizadas por Bakst (1994;, Freedman et al (2001), Miranda et al (2009) e Moraes et al (2009). Algumas pregas apresentaram maior concentração de GHEs e de GIs em relação às outras, e, mesmo dentro de uma prega, foram encontradas regiões com densidade maior de GHEs e de GIs do que em outra.…”

“…As glândulas da junção uterovaginal são consideradas como o principal local de armazenamento de espermatozoides, pois estes atingem primeiro esta região, permanecem nela por tempo maior e são liberados continuamente em direção ao infundíbulo distal (Fujii e Tamura, 1963;Bobr et al,1964). Moraes et al (2009) consideraram as GIs como o mais importante sítio de armazenamento de espermatozoides, pois nessa região ocorre a fertilização.…”

RESUMOPara determinar o tempo de permanência de espermatozoides nas glândulas hospedeiras de espermatozoides (GHEs) e nas glândulas infundibulares (GIs) de codorna de corte (Coturnix coturnix coturnix), foram utilizados 12 machos e 66 fêmeas, totalizando 78 codornas em fase reprodutiva. As fêmeas foram distribuídas em 11 grupos e acasaladas por 24 horas em gaiolas individuais. Os machos, utilizados de modo intercalado, foram separados do contato com as fêmeas e colocados em descanso. As aves do grupo-controle (G0  seis fêmeas) foram abatidas no início do experimento, enquanto as 60 fêmeas acasaladas foram distribuídas em 10 grupos (G1 a G10, com seis fêmeas cada) e abatidas a cada período de 24 horas, de forma sequencial. Fragmentos foram obtidos da região uterovaginal e do infundíbulo e submetidos às análises histológica, histoquímica e histométrica com técnicas de rotina. Os resultados morfométricos mostraram que 46% das GHEs continham espermatozoides em seu lume no primeiro dia após o acasalamento, diminuindo gradativamente nos dias posteriores chegando a 3% no quinto dia. Nesse período, os espermatozoides ascendem em direção às GIs, onde permanecem viáveis e férteis por, pelo menos, 96 horas após deixarem as GHEs, possibilitando a postura de ovos férteis por 10 dias, em média, após o acasalamento.Palavras-chave: codorna europeia, glândulas hospedeiras de espermatozoides, morfometria ABSTRACT Sperm-Storage Tubules (SSPs) and Infundibular Tubules (ITs) are the structures responsible for sperm storage in the oviduct of birds, snakes, alligators and turtles after mating.

Gross and Histomorphological Study of the Ovary and Oviduct of Turkey Hen with Especial Emphasis on the Sperm-Host Gland

et al. 2021

Turkey bird is one of the popular poultry species which is reared primarily for meat production and considered as one of the major sources of animal protein. With such importance of this species, this study was designed to investigate the gross and histomorphology of the ovary and oviduct with especial emphasis on sperm-host glands of the turkey hen involving ten mature female turkeys (Meleagris gallopavo). The present study highlighted the distribution pattern of sperm-host glands (SHGs) in the oviduct of turkey hen that has a potential role in producing a fertile egg in poultry industries. The oviduct of turkey consists of the infundibulum, magnum, isthmus, uterus, and vagina which are sole distributors for making nutrition enriched egg. The tissue samples were collected from the ovary, different segments of the oviduct and especially uterovaginal junction (UVJ) and infundiomagnal junction of the oviduct. The ovaries and the oviducts were dissected and fixed in Bouins solution and processed for a light microscopic study. Histologically, the left ovary of turkey consisted of an outer cortex and inner medulla, with different stages of follicles. In all areas of the oviduct except the infundibulum and vagina, the tunica mucosa epithelium was lined with ciliated pseudo stratified columnar epithelium, and the lamina propria-submucosa contained branched tubular glands. Sperm-storage tubules were observed in the uterovaginal junction and infundibulo-magnum junction. These tubules were mostly branched, slightly coiled and extended into the lamina propria from the bases of the mucosal folds. These glands had proximal and distal parts; the proximal part was lined by pseudostratified columnar epithelium and distal part by non-ciliated simple columnar epithelium. The number of sperm host glands was more at uterovaginal junction than infundibulomagnal junction. The sperm-host glands might play a functional role in the storage and release of spermatozoa from the SHGs in response to oviposition or ovulation. The results would help poultry scientists and farmers in developing effective disease control and growth strategies.
