Could somebody be promoting more and more infertility until their Messiah comes?

In the World to Come , the hyper-fertility that once existed in Eden will be restored. women will, painlessly, bear children every day (they envisioned this as a good thing; perhaps they were being hyperbolic). The Sages have even more to say about the fruitfulness of the earth in messianic times: trees will bear ripe fruit daily, and even wild trees will become fruit bearing. Wheat will grow as high as palms, and wheat grains as big as kidneys. A single grape will require a wagon to move and people will simply tap them for juice as they would a keg (Ket. 111b; Shab. 30b; Nidd. 31b; EY; Sefer ha-Raziel; Igeret ha-Kodesh).
