The strongest sperm will travel through the cervix the opening of the womb, or uterus , and into the fallopian tubes. A single sperm and the mother's egg cell meet in the fallopian tube.
When the single sperm enters the egg, conception occurs. The combined sperm and egg is called a zygote. The zygote contains all of the genetic information DNA needed to become a baby.
Half the DNA comes from the mother's egg and half from the father's sperm. The zygote spends the next few days traveling down the fallopian tube. During this time, it divides to form a ball of cells called a blastocyst. A blastocyst is made up of an inner group of cells with an outer shell. The inner group of cells will become the embryo.
Reproductive applications will have to wait until IVG is fully vetted for efficacy and safety, ensuring it doesn't produce babies with genetic diseases or birth defects.
In the meantime, nonhuman primate studies will be invaluable, but Orwig notes that relatively few labs have the capacity to conduct such research. From here, a number of preclinical human tests are necessary, Daley says. These tests could include the production of embryos with IVG and the derivation of embryonic stem cells, as well as whole genome sequencing on these cells and a full characterization of their ability to differentiate into other cells.
But in the United States, there are major research limitations on human embryos. The creation and subsequent destruction of human embryos from IVG for research purposes would make studies ineligible for public funding, and in some states outright illegal.
These hurdles could suggest that people wanting IVG procedures may be forced to look outside the United States, but Sonia Suter , a law professor at George Washington University who has previously written about the potential benefits and harms of IVG , doesn't think that's likely. ART is sometimes described as the 'Wild West. Experts believe IVG will eventually become safe enough to clear regulatory obstacles. Then it becomes a question of how we employ the technology.
Naturally, IVG would be used to restore reproduction in people with incurable infertility issues, such as those due to cancer and chemotherapy, but Zev Rosenwaks doesn't foresee it replacing natural human reproduction in fertile people. Still, some may prefer to use IVG to have babies from embryos that are prescreened for genetic diseases, which may ultimately reduce the levels of disability in society, Suter says.
Also, IVG won't do away with traditional IVF, but it may revolutionize the field, making egg donors obsolete, eliminating the need for hormonal stimulation techniques, and ultimately reducing costs.
Overall, the biggest demand for IVG may come from same-sex couples, Suter says. She and Hayashi of Kyushu University have received numerous inquiries from gay and lesbian couples wanting children with both parents' heritage. This application, however, may come a bit further down the line, as there are additional technological issues to work out. However, this movement occurs regardless of whether you're standing up, lying down, or standing on your head. No one is certain whether lying down after sex helps, however, there has been some research on IUI intrauterine insemination treatment that indicates it might be helpful.
That is more than enough time. The female orgasm is not required for baby making, and plenty of women conceive without it. But could it help? The research isn't clear, but some studies indicate it just may give sperm a boost.
One theory is that female orgasm helps move the sperm up from the cervix to the fallopian tubes. Another is that orgasm makes you feel sleepy, which increases your odds of remaining horizontal after sex which may or may not help with conception—see the information just above this!
Personal lubricants with spermicide are an obvious no-no when it comes to conception sex. What about the regular lubricants? Unfortunately, lubricants like KY Jelly are not sperm-friendly.
This is an especially important issue, since couples dealing with infertility may experience stress during sex, which means fewer arousal fluids. Plus, hormonal imbalance can lead to less cervical mucus. The good news is there are fertility-friendly lubricants available. You could also use plain no fragrance baby oil. As part of fertility treatment, you may be told when to have intercourse "doctor prescribed sex". If you're taking Clomid, your doctor will help you choose the best days to boost conception.
Your doctor may tell you to use an ovulation predictor kit at home. Alternatively, she may detect your most fertile days for you by using ultrasound and blood work to predict ovulation.
This can be very stressful for a couple. Some men may experience performance anxiety. To cope, consider making a date of your "scheduled sex," maintaining a sense of humor about the situation, and being patient with one another. You may feel alone and frustrated. You should know that having trouble with sex when trying to conceive is common. There are things you can do, though to improve your sex life. Sex shouldn't be painful.
If it hurts, something is wrong. Surprisingly, only 1 in 4 women will ever tell their doctor about their pain. What should you do if you want to get pregnant but sex hurts?
