Answer: Yes the pre ejaculation contains sperm. That is why the pull out method does not always work, and you still can get pregnant. So use condoms or another birth control method. There are many to choose from but you can still catch an std so condoms or abstain is your best method.
Answer: Fsh is follicle stimulating hormone. It is secreted by thepituitary gland and, very simply, it helps the ovaries to releaseeggs. If a woman is short of this hormone the ovaries may notdevelop properly, and ovulation may not occur. It is also necessaryin men for the development of the testes and the production ofsperm. If it is supplied artificially it can improve fertility.
Answer: Egg cells, or ova, are complete cells and have mitochondria. Spern cells are mobile packets of DNA, running on glucose and have no internal structure or organelles. A tightly-packed helical mitochondrial sheath surrounds part of the sperm tail. This is strange, however, because the sperm cell does not appear to produce energy by oxidative phosphorylation. Oxidative phosphorylation occurs in mitochondria. The sperm appears to produce all of its energy needs by glycolysis, which does not need mitochondria.
Sperm do not contribute very many mitochondria to the egg upon fertilization. So most people get their mitochondria from their mothers.
Answer: Healthy diet that includes folic acid and vitamin E has been advocated by some. Appropriate exercise and hygiene. Avoid STD because some of them can cause mechanical disturbances to fertility (Chlamydia can block the fallopian tubes). Just keep general good health, including a healthy weight. Nonetheless, some fertility problems result from more serious problems that involve antibodies, endocrine abnormalities, vascular disorders and reaction to medications. Consult your doctor. Remember that fertility problems can affect men and women.
