[123] This is an instinctive impulse under all strong emotion in primitive

blood-pressure Haig remarks: "I think that as the sexual act produces low
and falling blood-pressure, it will of necessity relieve conditions which

The germ cell never comes into the sphere of consciousness and cannot
therefore concern us in the psychological study of the phenomena of the
sexual instinct. But it is otherwise with the sperm cell, and the seminal
fluid has a relationship, both direct and indirect, to psychic phenomena
which it is now necessary to discuss.

While the spermatozoa are formed in the glandular tissue of the testes,
the seminal fluid as finally emitted in detumescence is not a purely
testicular product, but is formed b
