Women would be subject to the law from the moment of fertilization.

The less water movement, the better the chance for fertilization.

This is only the beginning in our discussion on fertilization.

The young hatch within one to six days of fertilization.

But such fertilization does not work if the varieties are too different.

It would not be expected to interfere with anything but fertilization.

This usually happens - but not always - about six days after fertilization.

Many members of the medical community accept fertilization as the point at which life begins.

For example, the embryo is 0 whole weeks old during the 1st week after fertilization.

A couple has religious objections to fertilization taking place outside the body.

From fertilization to birth usually takes about 266 days for humans.

They also release one egg each month for possible fertilization.

The growth and development occurs without fertilization by a male.

Fertilization should be done every month or twenty to thirty days.

They also require little fertilization because of their vigorous growth.

In species with internal fertilization, the female is usually the one to take care of the young.

This kind of egg became possible only with internal fertilization.

Embryos that are likely to die do so in the first few days after fertilization.

Besides, it is not so clear that an individual life begins at fertilization.

After the fertilization of the eggs, the male will guard them for at least six months.

While they may have used internal fertilization, this has yet to be demonstrated.

If in vitro fertilization had been available during those 20 years, I would have tried it.

The embryos, though only a few days past fertilization, are destroyed in the process.

The federal government does not pay for research related to human fertilization and early embryo development.

While at the Institute he began to study human fertilisation.

The process of fertilisation in a pine takes even longer.

This allows fertilisation to take place inside the woman's body.

Fertilisation is external to the body but inside the tube.

Of course, this follows from fertilisation taking place in a single cell.

Central to the debate is the status of the human egg after fertilisation.

Because the eggs are laid on land, internal fertilisation is needed.

These, when combined by fertilisation, produce the new set of 23 pairs.

Reproduction takes place in the spring, and fertilisation is external.

These may get sucked into another sponge and then fertilisation take place.

If they are sucked into another sponge, fertilisation can take place.

Large numbers of small eggs are produced and fertilisation is external.

The last method of fertilisation is the more common.

For them, fertilisation within the female is the rule.

One of these is a normal fertilisation, which produces the embryo.

The Church regards fertilisation as the beginning of life.

Only after several days does it fuse with the egg and so complete the long process of fertilisation.

Such fertilisation within the body is unusual among water-living animals.

All plants release at the same time, maximising its fertilisation.

Human reproduction takes place as internal fertilisation by sexual intercourse.

In 1987 the framework for human fertilisation and embryology was created.

His specific area of study was the fertilisation process in mammalian reproduction.

Pollen and a stigma are the two components needed for fertilisation.

The female produces up to 2 million eggs at a time, and fertilisation is external.
