For men, that's sperm and for women it's eggs.

POU2AF1 and PROM1 have been proposed as possible markers.

I actually found three separate recipes in the literature.

Sperm that sit around in the body for a week or more start to develop abnormalities that make them less effective at head banging their way into the egg.

Testicular pain is reported in up to one fifth of cases.

The first is that of chemotaxis which directs the movement of the sperm towards the ovum.

It wasn't spurted or thrown or ejected under great force.

Theodoor van de Velde was something of a semen connoisseur.

Alfred Kinsey decided to calculate the average distance traveled by ejaculated semen.

My father's sperm somehow met my mother's egg, and they fused.

Difference human Neanderthal is sperm and testis, smell and skin.

And in the other case, the sperm is carrying an X chromosome, meeting the X chromosome of the egg.

Marriage manual author and semen sniffer Theodoor van De Velde (Laughter) has a line in his book.

And Masters and Johnson looked to see if the semen was being sucked up.

But he wrote in this book, Ideal Marriage he said that he could differentiate between the semen of a young man, which he said had a fresh, exhilarating smell, and the semen of mature men, whose semen smelled quote, Remarkably like that of the flowers of the Spanish chestnut.

One fine day Alfred Kinsey decided to calculate the average distance traveled by ejaculated semen.

One set of chromosomes came from the nucleus of the ovum and the second set from the nucleus of the sperm.

In fact, the whole technology of sperm extraction for spinal cord injured males was invented by a veterinarian.

And in this scenario, I want to imagine that, in one case, the sperm is carrying a Y chromosome, meeting that X chromosome of the egg.

In the womb, a sperm meets the egg and a zygote is formed.

And in the artificial semen was a radio opaque substance, such that it would show up on an X ray.

It is the sperm in the semen that are of importance, and therefore semen quality involves both sperm quantity and quality.

The husband's consent has to set out whether he agrees to artificial insemination of his wife with his sperm even after his death.

The coordinates of the site to be placed under surveillance are kept secret by the surveillance team, and the Iraqi side is usually informed of them during the flight towards the site.

But he wrote in this book, Ideal Marriage he said that he could differentiate between the semen of a young man, which he said had a fresh, exhilarating smell, and the semen of mature men, whose semen smelled, quote,

This advance notice is necessary for the purpose of restricting air defence weapons in the area over which the flight is to be made, in order to protect the safety of the aircraft.

This shows why the consequences of online activities need to be thought through carefully in advance by those involved in uncovering and broadcasting rights abuses.

Theodoor van De Velde, a slight seminal odor can be detected on the breath of a woman within about an hour after sexual intercourse.

Shy but ambitious pig farmers, however, can purchase a this is true a sow vibrator, that hangs on the sperm feeder tube to vibrate.

Doctor Kinsey had heard and there was a theory going around at the time, this being the 1940s that the force with which semen is thrown against the cervix was a factor in fertility.

I did have to explain it to my nine year old late last week penises are structures that transfer sperm from one individual to another.

Since females only have X's to pass on in their egg cells, and males can give either an X or a Y in their sperm cells, the sex is determined by the father and the chance of producing a male or a female is 50 50.

According to 1930s marriage manual author, Theodoor van de Velde, a slight seminal odor can be detected on the breath of a woman within about an hour after sexual intercourse.

In the event of artificial insemination of a woman with the sperm of a man who had not granted his consent thereto or had declared his consent void, the issue of the child's filiation will be settled pursuant to the provisions of the Family Law Act.

They actually perform a surgery, take them out of the ovaries of the mother, and then they fertilize them with semen, either it might come from the father or a sperm donor, so then all of these becomes zygotes once they're fertilized with semen.

Doctor Kinsey had heard and there was a theory kind of going around at the time, this being the 1940s that the force with which semen is thrown against the cervix was a factor in fertility.

In vitro fertilization (IVF) is the process in which a mature ovum is surgically removed from a women's ovary, placed in a medium with sperm until fertilization occurs and then placed in the women's uterus.

And of course, we don't do these experiments in humans, but just by coincidence, my colleague has shown that men who have low sperm count, low semen quality have significantly more atrazine in their urine.

Work? Work!

Oh, no, work, work...

But the work. The work?

What to do! What to do! Why?
