The hormonal pattern was studied in 54 animals: 34 heifers with seasonal anoestrus, 13 cows with post-partum anoestrus, 5 cows with nymphomania and 2 cows superovulated. Seasonal and post partum anoestrus are characterized by basal levels of progesterone, FSH and LH, while oestradiol level is more variable and higher in post partum anoestrus due to the proper activity of the ovary. Nymphomania is a hyperfolliculinemic syndrome; cystic puncture leads to a fall in oestradiol and a surge in FSH and LH but of inequal intensity. The level of the latter hormone is often too low to induce luteinization; cystic degeneration of the ovary is associated with LH deficiency. In superovulated cows, hormonal pattern is like in normal cyclic cows but more pronounced. [less ▲]
