how to pregnant safely before to late

now thanks to the scan used in the Fertility MOT, it is possible to predict future fertility, which allows women to make informed choices.some people know the "body clock" refers to the decline in a woman's fertility as she grows older.



Those with a low ovarian reserve can start trying to become pregnant sooner than originally planned or freeze their eggs until the time is right.But they might not realise that it doesn't tick away at a constant rate.

The rate of decline in fertility speeds up from about 35 until the menopause sets it.



While many factors affect a woman's fertility, including illness or disease,drug treatments, accidents, smoking and pollution, age is the biggest factor. not just about the number of egg, quality, too, making it less likely that any remaining eggs will become fertilised and develop normally.



An older egg sometimes become fertilised, but there is a greater risk of miscarriage or birth abnormalities. It may be that the reduced fertility seen with ageing is thereforepart of the body's natural "safety mechanism". During a woman'snormal cycle, the body selects the "best" eggs to ripen for fertilisation.

Each month at least one healthy egg is passed during menstruation. This means unless a woman conceives, the "best" eggs are discarded by the body. that remain growolder, and are possibly of a lower quality.



some women are born with about two million eggs - but bythe time a woman turns 20, she only has about 50,000 left. This quantity gradually declines until a woman reaches 35, after which time the decrease rapidly speeds up. we can learn from this fact.

Summary:sapos123
Popular Photography named the Nikon D300 for their official "Camera of the Year 2007" award.

The magazine also reviewed the camera, and noted that "Nikon Capture NX" software was packaged with the camera.

The Nikon D300 is a 12.3-megapixel professional

DX format digital single-lens-reflex (dSLR) camera that Nikon Corporation announced on 23 August 2007 along with the Nikon D3 FX format camera.

It is designated by Nikon as the ultimate in DX format performance.

The Nikon DX format is an image sensor format of approximately 24×16 mm.

Its dimensions are about 2/3 those of the 135 film format (29mm vs 43mm diagonal, approx.).

The format was created by Nikon for its digital SLR cameras, many of which are equipped with DX-sized sensors.

It is very similar to the new D3, with the main difference being that the D300 uses a DX sensor instead of an FX sensor.

In addition, the D300 is slightly more compact than the D3.

It offers both high resolution and high speed (being able to capture 6 frames per second, and 8 frames per second with the addition of an optional MB-D10 battery pack).
