TL;DR: The ovarian cycle of the toad can be broadly classified into prespawning, spawning, spawning and postspawning-cum-preparatory period (September-March), based on the seasonal changes in the gonadosomatic index, diameter of the largest oocytes and ovarian histology.
Abstract: Oogenesis in the toad is of continuous type occurring throughout the year. The prefollicular cells divide mitotically to increase their number, to surround the developing follicles. The vitellogenesis begins from periphery and progresses towards the centre. The theca and granulosa layers in the mature follicles cannot be clearly differentiated. Binuclear oocytes are rarely found.The ovarian cycle of the toad can be broadly classified into prespawning (April-May), spawning (June-August) and postspawning-cum-preparatory period (September-March). The classification is based on the seasonal changes in the gonadosomatic index, diameter of the largest oocytes and ovarian histology. The breeding activity of the toad coincides with the rainy months of monsoon.

TL;DR: Melatonin injection either in the morning or in the evening decreases spermatogenesis as well as the Leydig Cell nuclear area in toad, whereas if administered twice daily (morning+evening) it shows no such effect.

TL;DR: Leydig cell nuclear area and 5-3β-hydroxysteroid dehydrogenase activity were increased in the testis of Bufo melanostictus 2 days after a single short-term cold exposure and returned to normal values 4 days later.
Abstract: Leydig cell nuclear area andΔ5-3β-hydroxysteroid dehydrogenase activity were increased in the testis ofBufo melanostictus 2 days after a single short-term cold exposure. Both parameters returned to normal values 4 days later.

TL;DR: Four new species of nyctotherid ciliates of the sub-genus Aduncuperistomatus Grasse 1928 from anuran amphibians in India are described, characterised by the presence of a distinct sub-oesophageal canal, typical shape of the macronucleus and distinctly different “V” shaped structures.
