Is Iila' valid from a husband who has undergone partial castration or emasculation?

Primary text

If the eunuch whose testicles were removed or crushed retains enough of his organ for intercourse, or if the man who is a Mughbuh (lacking seminal vesicles or testicles) retains enough of his organ for intercourse, then his Iila' is valid because he is capable of intercourse, even if he secretes a thin fluid.
