Sperm Meet Egg
Back to School: Perhaps reviewing anatomy is key here. Sperm have to find the cervix, swim through it. They they have to swim inside of the uterus until they find the fallopian tubes and then they have to swim through the fallopian tubes and then find the readied egg as it is released from the ovary. This process takes one to five days. To complete. ...Read more
Is there any method to know immediately when sperm meets egg? This is a doubt I have in my mind always...
No, there is no way: A sperm is a single cell, as is the "egg". Sperm enters the egg with no fuss or explosion. Your body comprises billions of cells And you never feel anything as relates to only a few cells. Compare sperm meeting egg to a single worm burrowing into a mountain. Earliest proof of pregnancy is a positive urinary pregnancy about 7 days after a missed period. ...Read more

Before implantation: Hcg is secreted by the embryo after fertilization but before implantation. The embryo reaches the blastocyst stage before it implants, with an inner cells that becomes the fetus, and trophoblast cells that make HCG and become part of the placenta. A little HCG is produced before implantation, but by the time we can *detect* HCG with a blood or urine pregnancy test implantation has already occurred. ...Read more

Does conceive mean day I had sex or when sperm meet tha egg or got pregnant I am so scared because I made a mistake?
Similar question: I think I answered most of this in the last question. If not, ask again and I'll give you definitions, but that isn't really going to help you with what you really wanted to know. Your last question was better for what I think you really wanted to know. ...Read more
After ovulation, egg is released from the ovary to the uterus. Now will the sperm meet the egg in uterus or fuse in ovary?
Swimming Sperm: Two to five days. It has to find the cervix opening, swim through the cervical mucous, up and into the uterus, find the opening to the fallopian tubes, transverse these and then swim into the pelvis and find a readied egg. ...Read more

No way to know: In my opinion, your sexual partners were too close together to determine with any accuracy. This will require a paternity test. ...Read more
Is conception the days of sex, or when sperm and egg meet or when the egg actually implants itself. How long after sex is true "conception"?
Not a medical word:
Conception is not really a medical word. We could think about it as a multi-step process.
Fertizilation is when the sperm and egg meet, a few hours after sex, and the sperm is able to penetrate the outer layer of the egg. Implantation of the fertilized egg, now called a zygote, and soon to be a blastula, happens several days later when it arrives in the uterus. ...Read more
If it can take a rather long time for sperm to meet an egg, then is it possible that douching or showering could remove semen, sperm and prevent pregnan
Is it true that fertilization can still happen 24 hours after the egg is released? What if the egg meet the sperm after 24 hours?
Maybe: Difficult question to answer because there's no way of knowing 'exactly' when the egg is released. Good evidence suggests that 10-12 hours is the limit for fertilization, although it 'may' extend as much as 24 hours. ...Read more

I had sex 5 days before what I think is my period. Could I be pregnant? I was told that the egg & sperm could meet durring my period bc it was so close
30 min: It has been estimated that the fastest swimming sperm can reach the egg in about 30 minutes (michael phelps?). On the other hand, conception can occur as many as five days after sex or possibly longer, as strong, healthy sperm can survive for about that many days (and perhaps even longer) in the supportive environment of the fallopian tubes as they wait for an egg to be released, if not already. ...Read more
