Table 1 Reference values for interpretation of GnRH stimulation test results after removal of ovarian remnants [8, 38]

From: A laparoscopic approach for removal of ovarian remnant tissue in 32 dogs

plasma parameter

time point

cut-off value (ovariectomized)

LH

Basal (before GnRH)

> 3.4 μg/l

FSH

Basal (before GnRH)

> 11.0 μg/l

FSH: Estradiol-17β ratio

Basal (before GnRH)

> 0.66

Estradiol-17β

120 min after GnRH

< 21.3 pmol/L

Estradiol-17β

Basal (before GnRH)

< 7 pmol/l → no ORS

7–21.3 pmol/l → not diagnostic

  1. Time point is relative to the administration of GnRH during a GnRH stimulation test. An animal was considered completely ovariectomized if the measured parameters were > or < the presented cut-off values as specified
