An autonomous or involuntary function of the autonomic nervous system (ANS) is regulated such as intestinal motility, heart rates, contraction, blood vessel dilation and glandular secretion. The self-sufficient action is accidental and this behaviour is usually not understood. The SLA consists of successful pathways consisting of two series of neurons linked to the autonomous ganglia on the outskirts. The first neuron is called the Preganglion and the spinal cord or stem of its cell bodies. The axon of the PRG-neurons generates synapses of the pos-ganglion neuron grouped in the autonomous ganglia and whose axon enters the target organ. The Major pelvic ganglion (MPG) in the male rat is founded by somatotopically arranged efferent nerves on various pelvic organs. By contrast, the accessories of ganglia are especially internal to reproductive organs. In the short term, the unilateral removal of the pelvic ganglion will lead to mild symptoms of urinary, sexual and infertility. This research project aims to explain the organisation and topographic connections of large pelvic ganglion and accessory knots in male rats. The purpose of this study is to establish the neuronal population and the morphometry of their neurons. 35 male adult Wistar rats (250g-300g) had been used in this experiment. In the 12/12 hours of light / dark circles, the animals were held ad libitum with food and water. Techniques were employed in anatomy, histochemistry, histology, conduct and fertility. The pelvic plexus consists of intricate, anatomically interlinked, ipsilateral and contra-lateral commissural nerves, composed by two MPGs and three pairs of GAs (ganglia accessories) (GAI, GAII, GAIII). There are approximately 31 nerves in each MPG and 17 GAI and GAII. The efferent larger pelvic ganglion nerves provide information for different pelvic organs that regulate excretory, reproductive, and sexual functions, and the internal intervals of the GA are confined to reproductive organs within the urogenital rostral area and urinary bladder. The GA neuron soma range is greater than the MPG neuron field (p <0.05). 75% of total post-ganglionic pelvic neurons are present in the MPG. Unilateral MPG ablation (A-MPG) and bilateral GA (A-GA) generated frequency after weeks 1 and 3 but returned to normal levels during weeks 9 and 20. After ablation (respectively). Copulatory parameters in male rats are not modified by A-MPG or A-GA. The A-GA lowered the number of females who were pregnant (36% p <0.05). The pelvic plexus consists of connected, paired ganglia, and the main one and three accessories are the major pelvic plexus. Somatotopically structured epidermal nervous agents implant the pelvic organ. In comparison, GAs interview reproductive organs and bladder in particular. The A-MPG or A-GA will emit frequencies after ablation in week 1 and 3. Unilateral MPG or bilateral ABL elimination does not affect male rats' copulatory parameters. GA ablation in weeks 3 after ablation leads to infertility in male rats.
