Spermicides for birth control (contraception, pregnancy prevention)
Spermicides are chemicals that make the sperm unable to function, so we say it "kills" them.
Sperm donation
Sperm donation offers couples a way to have a baby if the male partner isn’t producing enough healthy sperm to conceive.
The production of spermatozoa is continuous throughout a man's life, however each spermatozoon has a limited life-span. Within the male testicle they last about a month.
Sperm Cryopreservation and Storage
Tissues and cells, including sperm, may be frozen and stored through a process called cryopreservation.

Contents The present study aimed to compare cat sperm quality after thawing using two different temperatures (37 and 70 degrees C) and to investigate the effects of post-thaw dilution on the sperm quality and longevity of ejaculated cat spermatozoa.
Since the X chromosome is larger than the Y, there is more DNA for the dye to attach to and, consequently, the sperm with the X chromosomes will appear brighter than those with Y-chromosomes.
Eating healthily is imortant, as sperm need vitamins A, C and E, and the minerals zinc and selenium if they are to develop properly. Folic acid is also important to help the testes produce normally formed sperm.
Sperm collection. If sperm cannot be collected by means of masturbation, they are surgically removed from a testicle Opens New Window through a small incision.
Sperm Count Obviously a low sperm count to begin with doesn't favor either sex, but a high sperm count favors boys.
Sperm motility: The sperm's ability to readily swim forward to fertilize the egg. Also referred to as sperm mobility.

During their journey, many sperm run out of energy before reaching the egg.

Spermicides: Chemical contraceptives that inactivate and kill sperm and to a certain extent form a barrier over the cervix. Spermicides are more effective when used in conjunction with other contraceptives such as condoms or diaphragms.
Sperm Morphology -- A semen analysis factor that indicates the number or percentage of sperm in the sample that appear to have been formed normally. Abnormal morphology includes sperm with kinked, doubled, or coiled tails.
Sperm motility: The ability of sperm to move and swim quickly.

Sperm: the facts
A man typically produces something like 200 million to 500 million sperm per ejaculation, but normally only one fertilises the egg.
As sperm meets egg, fertilization occurs and your baby-to-be takes form — as a tiny group of cells.

ANTISPERM ANTIBODIES: Antibodies are produced by the immune system to fight off foreign substances, like bacteria. Antisperm antibodies attach themselves to sperm and inhibit their movement and ability to fertilize eggs.
Q What sperm disorders can cause male infertility?
Disorders of sperm production and development are the most common causes of male infertility.
Sperm meets egg within the fallopian tube and the miracle of life begins. Although several sperm may penetrate the egg's outer layer, only one sperm will enter the ovum and fertilize it.
Sperm Wash - A process that involves separating sperm from seminal fluid to remove nonmotile sperm cells and any other characteristics that could impair fertility.
Sperm, on the other hand, can live several days in your body. Sexual intercourse can be a few days before ovulation and still make a baby. The window for baby-making is considered to be 5 days before an egg is released to one day after.
Sperm live 72 hours (the best swimmers usually give up at about 48 hours, however) and the egg about 48.
Spermicides are available without a prescription in drugstores. They contain a chemical that kills sperm. Spermicides are sold in several forms including foam, cream and jelly.

Low sperm count (for males)
The normal sperm count ranges from 20 million to 100 million sperm per cubic centimeter. Counts below 20 million may be a cause for difficulty in conception.
The sperm and egg join in the fallopian tube and fertilization has occurred. Only one sperm will break through, and the egg instantly shuts down. No more sperm will be admitted. Identical twins or multiples may be formed if the egg then splits in two.

When a sperm meets an egg in the fallopian tube, fertilization � union of egg and sperm � can occur. If this happens, the fertilized egg moves down the fallopian tube to the uterus where it attaches and grows into a fetus.
Absent sperm - the semen doesn't contain any sperm.

After the sperm enters the vagina and reaches the fallopian tubes, it fuses with the oocyte or the female egg to form a zygote
- Zygote: The zygote is the single cell fusion of the sperm and the ovum.
Immature sperm (germinal cell) - Sperm that are not fully mature and that have low motility.
Implantation - After fertilization, the egg starts to embed into the uterine lining where it starts to develop as an embryo.
