10 Questions
What is the definition of anestrus?
Absence of ovarian cyclic activity
What is true anestrus?
Anestrus due to smooth ovaries or without palpable follicle and CL
What is the most common single cause of infertility in buffaloes?
Anestrus
What is the process by which the uterus attempts to return to its pre-pregnancy size and condition?
Involution
What may cause false anestrus?
Physiological factors like lactation and gestation
Match the following terms with their definitions:
Anestrus = Absence of overt signs of estrus Acyclicity = Absence of ovarian cyclic activity True anestrus = Anestrus due to smooth ovaries or without palpable follicle and CL False anestrus = Physiological (lactational, gestational, open days) or pathological (due to pyometra and chronic metritis) anestrus
Match the following causes of anestrus with their descriptions:
Congenital abnormalities = Includes ovarian agenesis or hypoplasia, free martinism, and intersexuality Retention of CL = Due to uterine pathological conditions of uterus like Pyometra, Chronic Metritis, and fetal mummification Physiological anestrus = Normal after 45 days post parturition due to the required period for normal involution of genitalia Involution = The process by which the uterus attempts to return to its pre-pregnancy size and condition
Match the following hormonal effects with their feedback effect on the hypothalamic-pituitary-gonadal axis:
High levels of placental and ovarian steroids = Negative feedback effect during late gestation Estrogens and progesterone = Prevailing during late gestation and exerting a negative feedback effect on the hypothalamic-pituitary-gonadal axis Negative feedback effect = Exerted by high levels of placental and ovarian steroids during late gestation Hypothalamic-pituitary-gonadal axis = Affected by the prevailing high levels of placental and ovarian steroids during late gestation
Match the following terms with their implications in infertility in buffaloes:
Anestrus = Most common single cause of infertility in buffaloes Failure to exhibit estrus = Broadly defines anestrus as the failure of animal to exhibit estrus Prepubertal anestrus = May be caused by congenital abnormalities like ovarian agenesis or hypoplasia, free martinism, and intersexuality Postpartum anestrus = May be due to retention of CL due to uterine pathological conditions of uterus like Pyometra, Chronic Metritis, and fetal mummification
Match the following terms with their descriptions:
Long anestrus periods = Known as true anestrus when due to cessation of cyclic activity Anestrus due to smooth ovaries or without palpable follicle and CL = Known as true anestrus Normal physiological anestrus = Occurs after 45 days post parturition and is required for normal involution of genitalia Pathological anestrus = May be due to pyometra and chronic metritis
