ivf egg fertilization

Fertilisation is the fusion of the female gamete (Egg or Ovum) produced in the embryosac and the male gamete produced in the pollen tube by the pollen grai..

Infertility in Males may be due to absence of sperm, low sperm count, abnormal sperms, autoimmunity (presence of antibodies in the male reproductive system itself), premature ejaculation and impotence. Infertility can be treated by either hormone treatment or modern methods of invitrofertilisation..

These come into play in the early stages of the reproductive process itself and prevents the formation of a fertilized egg (zygote). They can be as follow..

When the follicle is mature, the pituitary gland secretes another hormone called luteinizing hormone (LH). LH stimulates the follicle to rupture and release the egg. The release of egg is called ovulation and occurs between the 10 t h and the 16 t h day. The egg..

Parthenogenesis is a form of reproduction in which the ovum develops into a new individual without fertilisation. Natural parthenogenesis has been observed in many lower animals (it is characteristic of the rotifers), especially insects, e.g., the aphid. In many social insects, such as the honeybee..

Meiosis is a cell division occurs in reproductive cells (gametes). The male gamete is known as the sperm in animals and the female gamete is known as the ovum (egg). These gametes, after they are formed, have no future unless they unite to form a zygote, which then grows into an adult org..

. The head consists of the nucleus and a structure called the acrosome at the tip. The acrosome secretes lytic substances that break down the walls of the egg for fertilisation. The beating of the tail propels the sperm forward at the rate of 1-4 mm per minute. Each egg or ovum ..
