The ovulated oocyte (egg) is encapsulated by the zona pellucida to protect it. The sperm binds to the zone pellucida and undergoes an acrosomal reaction - where hundreds of acrosomes release their enzymes which digests the zona pellucida to prepare for implantation. The sperm then makes contact with the oocytes membrane and binds to the receptors. Once fertilisation occurs meiosis 2 occurs and the ovum's nuclei swell (now pronuclei) and approach each other in preparation for cell division.
This usually begins in the fallopian tubes and implantation usually occurs in the uterus (although it can happen in the fallopian tubes or ovary causing an ectopic pregnancy).

How create sperms in human body?
Sperms are produced in the testes through a process called spermatogenesis, which involves the division and differentiation of germ cells into mature sperm cells. This process is regulated by hormones such as testosterone and follicle-stimulating hormone (FSH). Sperms are stored in the epididymis and are released during ejaculation.
How many milliliters of sperms can human release?
That is approximately 9-10 .
How many litters of sperms does a human produce in one lifetime?
Infinite
Does human cells have flagella?
Yes some cells have. Sperms are good example
what cells of a human are diploid and which are haploid?
Exept sperms and ova all are diploid.
What is one type of human cell that doesnt have a nucleus?
Red blood cells do not have a nucleus. During their development, in a process called enucleation, their nucleus is expelled. This allows for more space in the cell to carry oxygen efficiently.
When does human begins its life?
The life of an human begins when the sex cells or gametes unite.Sex cells are the male sperms and the female ova.During copulation the sperms travels to meet the ova in order to fertilise with it.When they fertilise a zygote is formed which is single cell.
Does human penis has one hole for sperms and urine or two?
It all depends on if you have a prince albert or not.
Why nucleus is absent in human RBC?
Nucleus is a large organell.Lackness of a nucleus gives a large space for haemoglobin.
What is the name of the cell without the nucleus?
Human Red Blood Cells have no nucleus
What are the human cells one is the nucleus?
a nucleus is'nt a cell, it is the centre of cell
What human cell is the only one that does not contain a nucleus when it is mature?
red blood cell is the only human cell that does not contain a nucleus
