SPERM MORPHOLOGY

Male infertility does not occur if the sperms are healthy and vigorous in quality. In addition to the number of sperm, the sperm may be abnormally shaped, such as a large head, a short head, a twisted middle, or no tail.

Other sperm defects include bent tail, curled tail, stump-tail and misaligned tail.

Using strict morphological criteria to test whether a sperm sample is fertile or more of the sperm count is said to be considered normal.

Some couples decide to use IUI, IVF, or ICSI to improve their chances of parenthood based on sperm morphology results during infertility treatment.

Sperm morphology :

Sperm morphology refers to the shape of the sperm. These include head size and DNA content of the head, midsection appearance and tail structure. The shape of the head is important. Because it can affect the sperm's ability to penetrate the outer surface of the fertilized egg.

Sperm morphology is assessed during analysis of spermatozoa. Semen analysis also examines sperm motility and concentration.

Every male, whether fertile or infertile, has varying percentages of abnormally shaped sperm. There are many causes of abnormal sperm shape, including temperature rise, exposure to toxic chemicals, infection and genetics.

Normal sperms :

Oval-shaped head with a single tail without a coil in the middle. These can be run in a straight line. Abnormally shaped sperm usually have healthy genomes rather than normal sperm having more or less chromosomes.

Sperm has a large head. These often carry extra chromosomes and have problems fertilizing an egg. The condition can be caused by a homozygous mutation of the aurora genes. In this condition the sperms are abnormal. This is the father to his son.

The head of the sperm is smaller than normal. It is a small-headed sperm. A defective acrosome the pocket of enzymes in the sperm head used to enter the egg in the sperm may be the reduced genetic material.

Pinhead sperm :

Variant of small head spermatozoa. It is pin-like when paternal DNA content is absent. Having pinhead sperm is a sign of diabetes can mark.

Narrow head :

Spermatozoa with cigar-shaped heads. This may indicate the presence of varicocele in the male. The testicles can be exposed to this under conditions of high temperatures. This condition is often caused by abnormal chromatin or paternal DNA genetic material. An abnormal number of sperm chromosomes is shown in narrow-headed sperm.

An extreme variant of narrow-headed sperm is a thin narrow head. It is rarely identified. These may be due to a broken DNA varicocele or a rupture of the head.

It is abnormal sperm morphology which lacks acrosome. The inner parts of the sperm head are absent. It is a condition caused by premature ejaculation of sperm during development.

Headless sperm :

Sperm do not have heads. They are called cephalic sperm or lopsided sperm syndrome. It does not contain chromosomes. These may look like pinhead sperm. But on examination you can see that there is no small sperm head giving the sperm a loose appearance.

Sperms without a tail :

Sperm without a tail are called agate sperm. These spermatozoa are often seen during necrosis. These are caused by the death of cells in the organ.

Nuclear vacuole sperm :

Two or more large vacuoles in the sperm head with many smaller vacuoles. It is visible under a high magnification microscope. This show that these sperms have less fertilizing ability.

sperm images cause male infertility :

Although the most common cause of male infertility is low sperm count, the shape of the sperm is also important. Sperm morphology can affect fertility. Sperms need a specific shape to penetrate the outer layers of the egg.

People with sperm morphology problems can undergo IUI or IVF. Intracytoplasmic sperm injection can be used in addition to IVF. Antioxidants in male fertility supplements are recommended for 2 or more months.

The higher chance of success based on sperm morphological motility, quality spermatozoa can be selected and the sperm can be directly injected into the female's egg. The sperm and ovum combine to form an embryo in the uterus.
