Lack of sperm flow

The good news, there are some very tangible lifestyle changes that men can make to improve their sperm health and overall fertility. It is generally known that most men produce millions of new sperm every day. You also might not realize that when sperm are initially formed within the testicles, they lack the ability to swim forward or fertilize an egg until they make their way through the reproductive tract. Sperm are living cells within the male body and are subject to whatever conditions the rest of the body is exposed to throughout their development cycle.

Ejaculation worries – too little semen
What Your Semen Says About Your Health
Azoospermia leads to male infertility. During ejaculation, sperm move from the testes and the epididymis into the vas deferens. Tightening contraction of the vas deferens moves the sperm along. Secretions from the seminal vesicle are added and the seminal fluid continues to move forward toward the urethra. Before reaching the urethra, the seminal fluid passes by the prostate gland, which adds a milky fluid to the sperm to form semen.

How Cancer Can Affect Ejaculation
Sperm is the male reproductive cell , or gamete , in anisogamous forms of sexual reproduction forms in which there is a larger, "female" reproductive cell and a smaller, "male" one. Animals produce motile sperm with a tail known as a flagellum , which are known as spermatozoa , while some red algae and fungi produce non-motile sperm cells, known as spermatia. Sperm cells form during the process known as spermatogenesis , which in amniotes reptiles and mammals takes place in the seminiferous tubules of the testes. The spermatocytes then undergo meiosis , reducing their chromosome number by half, which produces spermatids. The spermatids then mature and, in animals, construct a tail, or flagellum, which gives rise to the mature, motile sperm cell.
Oxytocin Oxt is a peptide hormone and neuropeptide. It is normally produced in the hypothalamus and released by the posterior pituitary. Oxytocin is derived by enzymatic splitting from the peptide precursor encoded by the human OXT gene.
