“…We observed no change in the appearance or the weights of the ovaries, which indicates that there was little or no oedema of the sort observed after cutting the ovarian plexus (Lawrence & Burden, 1980). However, our procedure may also have interrupted any ovarian sensory fibres and preganglionic parasympathetic fibres since these could be expected also to accompany the blood vessels supplying the ovary (Labate & Reynolds, 1937;Burden & Lawrence, 1978). Lawrence & Burden (1980) severed the ovarian vascular pedicle and ovarian suspensory ligament.…”

Brief freezing of the ovarian vascular pedicle in rats reduced ovarian noradrenaline concentration, measured with HPLC, by 67% (P less than 0.01). Freezing of the ovarian suspensory ligament caused a 22% reduction (P less than 0.01) and 33% reduction (P less than 0.05) in 2 experiments. The numbers of adrenergic nerve terminals detected by fluorescence microscopy after these procedures were similarly reduced (P less than 0.01). Freezing of both the pedicle and the ligament produced complete sympathetic denervation in about 50% of the ovaries. From Days 2 to 10 after operation no noradrenaline or nerve terminals were detected in 14 out of 27 ovaries. Nerve terminals were also eliminated from the oviduct. Reinnervation of the ovary began between Days 12 and 30. It is concluded that the adrenergic innervation of the ovary is predominantly through nerves that accompany the vascular supply to the ovary and the ovarian suspensory ligament. Freezing of these routes is a simple and relatively atraumatic means of denervating the ovary for experimental studies.
