When your body reaches a certain age, your brain releases a special hormone that starts the changes of puberty. It's called gonadotropin-releasing hormone, or GnRH for short. When GnRH reaches the pituitary gland (a pea-shaped gland that sits just under the brain), this gland releases into the bloodstream two more puberty hormones: luteinizing hormone (LH for short) and follicle-stimulating hormone (FSH for short). Guys and girls have both of these hormones in their bodies. And depending on whether you're a guy or a girl, these hormones go to work on different parts of the body. For guys, these hormones travel through the blood and give the testes the signal to begin the production of testosterone and sperm. Testosterone is the hormone that causes most of the changes in a guy's body during puberty. Sperm cells must be produced for men to reproduce. In girls, FSH and LH target the ovaries, which contain eggs that have been there since birth. The hormones stimulate the ovaries to begin producing another hormone called estrogen. Estrogen, along with FSH and LH, causes a girl's body to mature and prepares her for pregnancy. So that's what's really happening during puberty - it's all these new chemicals moving around inside your body, turning you from a teen into an adult with adult levels of hormones.

What is the period between the fertilisation of the egg and the implantation of the embryo known as?
The period between the fertilisation of the egg and the implantation of the embryo is known as the pre-implantation period. During this time, the fertilized egg undergoes multiple cell divisions and forms a structure known as a blastocyst before implanting into the uterine lining.
When does implantation bleeding occur if at all?
Hi, Implantation bleeding occurs 6-12 days after intercourse when fertilisation of the egg has taken place. Not every woman experiences implantation bleeding and it is not as common as a lot of women think.
What is the difference between conception and implantation?
Conception refers to the moment when a sperm fertilizes an egg, creating a zygote. Implantation is the process by which the fertilized egg attaches itself to the uterus lining, around 5-7 days after conception.
What process occurs from fertilisation of an ovum to implantation about 6 days later?
After fertilization, the zygote undergoes rapid cell division to form a blastocyst. The blastocyst then implants into the uterine wall around 6 days after fertilization. This process is crucial for establishing a pregnancy.
What is post fertilization?
Post fertilization refers to the stage in reproduction that follows fertilization, where the sperm and egg have fused to form a zygote. During this stage, the zygote undergoes processes such as cleavage, implantation, and eventually develops into an embryo.
What animal has and fertilisation and implantation and gestation?

The order of THE 5 stage of birth?
the 5 stages that women put up through for birth is cell division, ovulation, implantation, fertilisation and copulation.
What is implantation bleeding and how soon can you get it?
When the fertilised egg (zygote) burrows into the wall of the uterus (implantation) it my cause a little bleeding, not more than a spot or two. This usually occurs 6-10 days after ovulation and fertilisation, so anything from a week before a period is due up until the period. About 25% of women have implantation bleeding.

Where does firtilisation happen?
Fertilisation normally occurs high up in the Fallopian tube. Once fertilisation has taken place development of a new individual begins immediately but it takes about 6 days before the growing structure reaches the uterus and becomes embedded in the lining of the uterus where it is receives nourishment from the mother's blood. This embedding is known as implantation. After implantation the developing embryo releases a chemical into the mother's blood preventing menstruation and so failure to menstruate is often the first sign of pregnancy.

What are the 2 kinds of fertilization?
The 2 fertilisation's are external fertilisation, or internal fertilisation. External fertilisation is the type frogs do.
From implantation through the 8th week of pregnancy what term is used to describe the developing child in the uterus?
