Kim Kardashian is pregnant with a boy? The reality star announced last night that she and Kanye West have “actually known baby No. 2’s gender for a while now,” according to E! News. But that would be impossible, unless…

…Kim underwent in vitro fertilization (IVF) with a designer baby embryo.

While Kim hasn’t said exactly how she got pregnant, or when, the reality television network confirmed, June 3, that her due-date is in December. That means, counting back nine months, she got pregnant in April.

Now here is where the baby math gets very fuzzy.

Kim Kardashian Was Told She’d Never Get Pregnant

If she got pregnant in April, the most she could be along is 12 weeks, and the least, eight weeks. According medical references, the earliest it’s possible to tell the sex of the fetus is around 18 to 20 weeks.

Most pregnant women undergo an ultrasound at four and a half to five months, according to Dr. Elizabeth Pryor, writing on Even then, she cautions, it’s not always possible to tell the sex of the baby.

Many doctors, however, prefer to wait until 30 weeks into a pregnancy.

Amniocentesis is another reliable method to check the baby’s chromosomes. The test is usually performed on woman over age 35 to check for possible genetic problems.

Kim is 34, so she may have had this test done. But it is never done simply to learn the sex of a fetus, because of the risk, according to medical references.

It involves inserting a needle into the uterus to remove a small amount of amniotic fluid. Even so the test is usually performed around 16 weeks, according to Pryor.

What really throws the math off is Kim’s statement that they’ve actually known baby No. 2’s gender “for a while now.” That definitely would be impossible, unless Kim underwent IVF treatments and was impregnated with a designer baby.

IVF has become an increasingly common procedure to help couples with infertility problems conceive children, according to medical references.

Will Kim Kardashian Pregnancy Raise or Lower Skank Quotient?

One of the first highly publicized instances of a couple choosing the sex of their baby occurred in 1996. Monique and Scott Collins made history by select their baby’s sex in the test tube through a process known as “preimplantation genetic diagnosis,” or PGD.

Only two years earlier, The Council on Ethical and Judicial Affairs, an arm of the American Medical Association, said using genetic selection for anything other preventing or curing specific diseases, is unethical.

Other bioethicists, including George Annas, chairman of Boston University medical school’s Department of Health Law, Bioethics & Human Rights, dispute that view.

As always, with Kim and the rest of the Kardashians, it’s impossible to tell where reality begins and ends, even though they are on a “reality television show.”

In any event, the evidence suggests that Kim underwent IVF treatment and had a designer embryo implanted.

For the sake of all the other women who are similarly situated, at her age, it would be the correct thing to do to come clean about her pregnancy.
