Nutrition and Oestrus and Ovarian Cycles in Cattle

End of Project ReportThe overall objective of this project was to establish the effects of both long- and short-term changes in nutrition on ovarian follicle dynamics and on the systemic concentrations of metabolic and reproductive hormones. In order to avoid the confounding effects of lactation, suckling and maternal–calf bonding, beef heifers were used in a series of three studies.European Union 3rd Framework Programme (Contract AIR3-CT94-1124

Management of anovulatory infertility

Anovulatory subfertility is a heterogeneous condition with various underlying causes, which should be identified with appropriate history taking, physical examination and relevant investigations. Optimisation of body weight is essential in either underweight, overweight or obese individuals. Women with hypogonadotrophic anovulation can be treated with pulsatile gonadotrophin-releasing hormone therapy or a gonadotrophin preparation containing both follicle-stimulating hormone or luteinising hormone activities. For normogonadotrophic anovulation, clomiphene citrate should be used as first-line medical treatment. Metformin co-treatment with clomiphene citrate may be considered in a subgroup of women with polycystic ovary syndrome who are obese or clomiphene-resistant. Ovulation induction with gonadotrophin or laparoscopic ovarian drilling is the next option. Dopamine agonist is indicated for anovulation as a result of hyperprolactinaemia. © 2012 Elsevier Ltd.
