The objective of this study was to investigate the effects of seasonality and phase of the estrous cycle on ovarian and oocyte morphology in domestic cats kept in a tropical region. The ovaries from 23 queens were collected after elective ovariohysterectomy at different stages of the estrous cycle and were classified according to the season upon collection (spring/summer vs. fall/winter). Based on the findings, we concluded that queens in tropical regions experience no seasonal influence on oocyte quality, but there is a minimal effect on ovarian morphology, with an increase in ovarian length during proestrus/estrus in the spring/summer period.

Abstract
The objective of this study was to investigate the effects of seasonality and phase of the estrous cycle on ovarian and oocyte morphology in domestic cats kept in a tropical region. The ovaries from 23 queens were collected after elective ovariohysterectomy at different stages of the estrous cycle and were classified according to the season upon collection (spring/summer vs. fall/winter). Based on the findings, we concluded that queens in tropical regions experience no seasonal influence on oocyte quality, but there is a minimal effect on ovarian morphology, with an increase in ovarian length during proestrus/estrus in the spring/summer period.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
