We are pleased to announce that, thanks to the financial support of our valuable
users, we are able once again, to import articles from the radio frequency range into
the EMF-Portal. Fortunately, we could close the gap in our literature inventory and
all newly published articles released up to April 30, 2018 have been included. In
order that we are able to import further publications released in the future, please
help us with your donation. Thank you very much!
The matured humanspermatozoon is about 60 µm long and consists of a head, a neck, a middle piece, and a long tail (flagellum) by which it propels itself with a vigorous lashing movement. The head contains the cell nucleus with the haploidchromosome set. The head is covered by the acrosome which contains enzymes used for penetrating the female egg. The neck contains the centrioles which are involved in the division of the chromosomes in the fertilizedegg.
The middle piece contains many spirally arranged mitchondria which provide ATP as energy for the sperm mobility. The tail executes lashing movements that propel the spermatozoon. Microtubules in the middle piece and parts of the tail enable the motion of the tail.
