debian networking linux-kernel tcp handshake

                          While debugging some strange behaviour with an Azure load-balancer, I noticed that my local Debian Stretch TCP stack was only establishing TCP connections with an even-numbered port. I do not start a single TCP handshake with an odd source port.
Is that intended?
