Products of Partitions

A partition of an integer is a way of representing a positive integer as a sum of other positive integers. For example, 4 can be partitioned in the following 5 ways

$4=1+1+1+1=2+1+1=2+2=3+1$

The product reduction of each partition is

$4, \ 1\times1\times1\times1, \ 2\times1\times1, \ 2\times2, \ 3\times1$

Out of these 5 products, $$2$$ of the products are odd ($$3\times1$$ and $$1\times1\times1\times1$$).

How many odd product reductions of the partitions of 40 are there?
