Shrila Prabhupada comments on Women Sannyasinis:

1.  From the Shrimad-Bhagavatam (3.24.41):

Translation:

  I shall also describe this sublime knowledge, which is the door to spiritual
life, to My mother, so that she also can attain perfection and self-
realization, ending all reactions to fruitive activities.  Thus she also will
be freed from all material fear.

Purport:

  Kardama Muni was anxious about his good wife, Devahuti, while leaving home,
and so the worthy son promised that not only would Kardama Muni be freed from
the material entanglement, but Devahuti would also be freed by receiving
instruction from her son.  A very good example is set here:  the husband goes
away, taking the sannyasa order for self-realization, but his representative,
the son, who is equally educated, remains at home to deliver the mother.  A
sannyasi is not supposed to take his wife with him.  At the vanaprastha stage
of retired life, or the stage midway between householder life and renounced
life, one may keep his wife as an assistant without sex relations, but in the
sannyasa order of life one cannot keep his wife with him.  Otherwise, a person
like Kardama Muni could have kept his wife with him, and there would have been
no hindrance to his prosecution of self-realization.
  Kardama Muni followed the Vedic injunction that no one in sannyasa life can
have any kind of relationship with women.  But what is the position of a woman
who is left by her husband?  She is entrusted to the son, and the son promises
that he will deliver his mother from entanglement.  A woman is not supposed to
take sannyasa.  So-called spiritual societies concocted in modern times give
sannyasa even to women, although there is no sanction in the Vedic literature
for a woman's accepting sannyasa.  Otherwise, if it were sanctioned, Kardama
Muni could have taken his wife and given her sannyasa.  The woman must remain
at home.  She has only three stages of life:  dependency on the father in
childhood, dependency on the husband in youth and, in old age, dependency on
the grown-up son, such as Kapila.  In old age the progress of woman depends on
the grown-up son.  The ideal son, Kapila Muni, is assuring His father of the
deliverance of His mother so that His father may go peacefully without anxiety
for his good wife.

My Dear Brahmananda,
...A female is never awarded the order of Sannyasam.  Because a female is never
considered independent and Sannyasam was never awarded to any female in the
past by the great Acharyas like Samkara, Ramanuja, etc.  The female Sannyasins
are to be immediately understood as pretenders or prostitutes.  In India they
have organised so many organisations where specially young females are
maintained to attract rich women-hunters who pretend to pose as righteous in
the society.  This is the age of Kali which plunders away spiritual sense of
the human being and it is only the Divine Grace of Lord Chaitanya Who can
protect us from all these dangerous pitfalls....
