A report demonstrated evidence of the effects of feminizing chemicals on male development in each class of vertebrate species as a worldwide phenomenon; these chemical are suspected of reducing the sex ratio and sperm counts in humans. Among the amphibians, salamanders regularly regenerate their legs, which are not very useful for movement in their aquatic environment , while frogs and toads, which are so much more dependent on their legs, are nevertheless unable to replace them. Sperm regeneration is the renewal of sperm supplies with fresh spermatozoa ready for fertilization. They are produced in flask-shaped structures containing nectar , which attract flies that transfer the spermatia to nearby hyphae for fertilization in a mechanism similar to insect pollination in flowering plants. In some ciliates, such as Blepharisma or Stentor , the nucleus may be elongated or shaped like a string of beads.
