Four megaspores are formed from meiotic division of megapore mother cell which is diploid. We know that diploid cells undergo meiosis to give haploid cells. So, it seems to me that megaspores are haploid.
During spermatogenesis, diploid spermatogonium cells undergo mitosis to produce primary spermatocytes, which then undergo meiosis I to form secondary spermatocytes. These secondary spermatocytes then undergo meiosis II to form haploid spermatids. Finally, spermatids undergo spermiogenesis to differentiate into mature sperm cells.
Ten spermatozoa will be produced from ten spermatids. Egg cells are not formed from spermatids.
The procedure may work with spermatids because they are haploid cells that have completed meiosis and are less complex than primary spermatocytes, which are diploid and undergoing meiosis. Primary spermatocytes are larger, more metabolically active, and have a more complex structure, which may make them less amenable to certain procedures.

Haploid
Each primary spermatocyte undergoes meiosis to produce four haploid spermatids.
4 spermatids are formed from one primary spermatocyte.
Spermatids are immature male germ cells that have undergone the first stage of spermatogenesis. They eventually develop into sperm cells through a process called spermiogenesis, where they undergo further maturation and differentiation. Spermatids have not yet developed the distinctive features of sperm cells, such as a tail for swimming.
During spermatogenesis, diploid spermatogonium cells undergo mitosis to produce primary spermatocytes, which then undergo meiosis I to form secondary spermatocytes. These secondary spermatocytes then undergo meiosis II to form haploid spermatids. Finally, spermatids undergo spermiogenesis to differentiate into mature sperm cells.
Four haploid spermatids are formed from one diploid spermatogonium through the process of spermatogenesis. Each spermatid contains half the number of chromosomes as the original spermatogonium.
Ten spermatozoa will be produced from ten spermatids. Egg cells are not formed from spermatids.

Primary spermatocytes are larger, more metabolically active, and have a more complex structure, which may make them less amenable to certain procedures.
Spermatids are not considered functional gametes because they are haploid cells in the process of differentiation into mature sperm (spermatozoa). They lack key structures and mobility needed for fertilization, such as a flagellum for movement and an acrosome for penetrating the egg. Only mature sperm are capable of fertilizing an egg during sexual reproduction.
One spermatogonia will produce four spermatids through the process of spermatogenesis.
epididymis
The primary spermatocyte is diploid(2n) and after first meiotic division it will produce 2 haploid(n) secondary spermatocyte and these in turn after second meiotic division will produce 2 more haploid secondary spermatocyte. Therefore by the end of Meiosis one will have 4 haploid secondary spermatocyte or spermatids.
Spermatids are stored in the seminiferous tubules of the testes in humans. They are formed from the process of spermatogenesis and eventually mature into spermatozoa (sperm cells).
