Effect of photic changes and olfactory impairment on reproduction in female south Indian gerbil.

Effect of exposure to constant light (CL), blinding and olfactory bulbectomy (OBX) on reproduction of adult and weanling female Tatera indica cuvieri was investigated. In adult females, CL induced changes in estrus cyclicity. Weanlings subjected to CL showed reduced ovarian weight. Blinding did not bring about changes in estrus cyclicity and reproductive organ weight (ovary and uterus) of either adults or weanlings. Estrus cyclicity of both adults and weanlings were affected consequent to OBX. In weanlings, OBX lowered the ovarian and uterine weight.

Olfactory bulbectomy-induced changes in the reproductive behaviour of the south Indian gerbil, Tatera indica cuvieri.

Male South Indian gerbils (T. indica cuvieri), both adults and weanlings, were olfactory bulbectomized (OBX) and changes in male reproductive behaviour were assessed. Consequent to OBX, majority of the adult males failed to ejaculate, and courtship behaviour has also been considerably reduced. All OBX weanlings were rendered incapable of ejaculation. However, maturational parameters, and organ weights (testes, epididymis and seminal vesicle) remained unchanged in OBX males.
