Does every testicle produce X and Y spermatozoids?!
Question: Yes.
Sperm cells are haploid - they have 23 chromosomes. They come from diploid (46 chromosome) cells. During meiosis, the diploid chromosomes pair off, and one of each pair goes to the resulting sperm cells. That includes the XY sex chromosomes, one sperm cell gets the X, the other gets the Y.
Not only does every testicle produce both, each X sperm cell has a matching Y, created at the same time, in the same place, from the same precursor.

Yes
ya dude.....
yes
yes, they do. Let me explain, how this work?
Spermatogenesis is the process by which male spermatogonia develop into mature spermatozoa. Spermatozoa are the mature male gametes in many sexually reproducing organisms. Thus, spermatogenesis is the male version of gametogenesis. In mammals it occurs in the male testes and epididymis in a stepwise fashion, and for humans takes approximately 64 days. Spermatogenesis is highly dependent upon optimal conditions for the process to occur correctly, and is essential for sexual reproduction. It starts at puberty and usually continues uninterrupted until death, although a slight decrease can be discerned in the quantity of produced sperm with increase in age. The entire process can be broken up into several distinct stages, each corresponding to a particular type of cell:
