Age, FSH dose and follicular aspiration frequency affect oocyte yield from juvenile donor lambs
(2007)Experiments were conducted to determine the effects of lamb age, frequency of follicular aspirations, and hormone stimulation by fixed or variable FSH dose, on the number of collected oocytes and their maturational competence. ... -
Alternate day and daily administration of GnRH antagonist may prevent premature luteinization to a similar extent during FSH treatment
(2005)BACKGROUND: This randomized controlled trial was designed to evaluate whether a GnRH antagonist given every other day could prevent premature luteinization in women undergoing IVF/ICSI treatment. METHODS: A total of 73 ... -
Assisted reproductive technologies in the reproductive management of small ruminants
(2012)In modern agriculture, assisted reproductive technologies are being used for out of season oestrus induction, enhancement of reproductive performance and genetic improvement. In addition, they can have substantial contribution ... -
Association of soybean-based extenders with field fertility of stored ram (Ovis aries) semen: A randomized double-blind parallel group design
(2013)Two consecutive randomized double-blind field fertility experiments were conducted over a 4-month period and aimed at evaluating the association of two commercial soybean lecithin-based extenders (AndroMed [Minitub, ... -
Bacteriological and epidemiological findings during examination of the uterine content of ewes with retention of fetal membranes
(2002)We included 92 pairs of ewes with or without retention of fetal membranes in a cohort study of 25 flocks in Southern Greece. We obtained two uterine content samples under aseptic conditions, by introducing a swab into the ... -
Blockage of ghrelin-induced prolactin secretion in women by bromocriptine
(2010)Objective: To investigate the effect of bromocriptine on ghrelin-induced PRL secretion in women. Design: Longitudinal study. Setting: University hospital. Patient(s): Ten healthy, normally cycling women. Intervention(s): ... -
Blood ghrelin, resistin, and adiponectin concentrations during the normal menstrual cycle
(2009)Objective: To investigate changes of ghrelin, resistin, and adiponectin levels in the circulation during the normal menstrual cycle. Design: Longitudinal study. Setting: The study was conducted at a university hospital. ... -
Changes in pituitary sensitivity to GnRH in estrogen-treated post-menopausal women: evidence that gonadotrophin surge attenuating factor plays a physiological role
(2004)BACKGROUND: The purpose of this study was to investigate changes in pituitary response to GnRH in post-menopausal women during substitution treatment with exogenous estrogen and progesterone. METHODS: Seven healthy ... -
Clinical, ultrasonographic and pathological features following unilateral vasectomy in rams
(2008)The effects of vasectomy on testes and related structures of animal species and men are largely disputable. These possible effects were studied in the ram, an established experimental animal model used to investigate ... -

Combined administration of gonadotropin-releasing hormone, progesterone, and meloxicam is an effective treatment for the repeat-breeder cow
(2009)In practice, the etiologic treatment of the repeat-breeder cow is nearly infeasible. In this study, we tested the hypothesis that a combined treatment would benefit the conception rate of repeat-breeder cows. The components ... -
Comparison between ultrasonographic and caliper measurements of testicular volume in the dog
(2008)The aim of this study was to compare the accuracy of two methods used to clinically estimate testicular volume in the dog. Caliper and ultrasonographic measurements of testicular dimensions (length, width and height) of ... -
Cord blood as a source of non-senescent lymphocytes for tumor immunotherapy
(2010)While proof of concept that the immune system can be harnessed to attack cancer cells has been established, only a minority of patients are cured with immunotherapeutic regimens designed to enhance host autologous immunity. ... -
Current and future status of ovulation induction in polycystic ovary syndrome
(1997)Great progress has been achieved during the last 20 years in the field of ovulation induction in patients with polycystic ovary syndrome (PCOS). Clomiphene citrate remains the first line of treatment for all anovulatory ...
