Explanation

In oocytes, a special, extremely prolonged form of diplotene occurs, called dictyotene. The primary oocyte undergoes the first three substages of prophase-I (laptotene, zygotene and pachytene) during late foetal life. The process is then, suspended during diplotene until puberty or thereafter. Therefore, dictyotene, lasts for months or even years. Diplotene is also known as diplonema
