    • Abstract


      The structural and functional integrity of the vas deferens and its role in ensuring the fertilizing ability, viability of spermatozoa and their survival in the vas deferens, are elucidated. The regulation of the function of the vas deferens and the differential androgen dependency of its two regions have been discussed in relation to its secretory and absorptive activities as well as its contractility. The importance of ascorbic acid in maintaining its functions has also been investigated.

      The potentiality of the use of an androgen antagonist, steroids (testosterone, estradiol benzoate), prostaglandins, copper devices, vasectomy, vasocclusive agents, effects of nutr itional deficiencies, human chorionic gonadotropin-antiserum and plant products as antifertility agents have been discussed.

      Forthcoming Special issue.

    • To trigger further research on plant mitochondria, the Journal of Biosciences is bringing out a special issue titled "Plant Mitochondria: Properties and Interactions with Other Organelles".

      Plant mitochondria are quite distinct and have unique features, such as a cyanide-insensitive alternate pathway. They also interact with chloroplasts to optimize photosynthetic carbon assimilation.

      Submissions are welcome until 30 July 2023. The contributions can be original articles, short communications, reviews, or mini-reviews on any topic related to plant mitochondria.

      Authors can submit their articles online at https://www.editorialmanager.com/jbsc/default2.aspx
