Ovarian function in 91 dairy cows with cystic ovarian disease was assessed by rectal palpation and by plasma hormone analysis before and after treatment. Plasma analysis showed that 84% of the cysts were correctly classified clinically and only these cows are considered further. Luteinised cysts occurred in 59 cows whereas only 18 had non-luteinised cysts. The mean plasma concentrations of luteinising hormone (LH), follicular stimulating hormone (FSH), progesterone, oestradiol and testosterone were not significantly different when compared with values at relevant stages of the oestrous cycle in normal cows. Success of treatment with progesterone, a synthetic prostaglandin, human gonadotrophin (HCG), or gonadotrophin releasing hormone (GnRH) was not dependent upon prior hormone concentrations, except for the prostaglandin which required active luteal tissue. LH and FSH concentrations in cows with luteinised cysts were not significantly different before and after successful treatment with GnRH or progesterone. Normal luteal function was not always established after treatment of non-luteinised cysts with GnRH.
通过直肠触诊以及治疗前后的血浆激素分析，对91头患有卵巢囊肿疾病的奶牛的卵巢功能进行了评估。血浆分析表明，84%的囊肿在临床上被正确分类，只有这些奶牛被进一步考虑。59头奶牛出现了黄体化囊肿，而只有18头有未黄体化囊肿。与正常奶牛发情周期相关阶段的值相比，促黄体生成素（LH）、促卵泡激素（FSH）、孕酮、雌二醇和睾酮的平均血浆浓度没有显著差异。使用孕酮、合成前列腺素、人绒毛膜促性腺激素（HCG）或促性腺激素释放激素（GnRH）治疗的成功率并不取决于先前的激素浓度，但前列腺素需要有活性的黄体组织。在用GnRH或孕酮成功治疗后，患有黄体化囊肿的奶牛的LH和FSH浓度没有显著差异。用GnRH治疗未黄体化囊肿后，并不总能建立正常的黄体功能。
