It does, at least according to a study in the July 2010 issue of Fertility & Sterility.
The authors surveyed 4976 clinical pregnancies from one large IVF center and found ninety-eight cases of monozygotic twins (MZTs) were diagnosed after first-trimester ultrasound evaluation (2% incidence). In naturally conceived pregnancies the incidence is about 0.25-0.5%.
The incidence in women transfering embryos from…
Dr. Arthur Wisot was quoted in the July 14th edition of the Los Angeles Times on the additional charges by the Medical Board of California against Octomom's doctor.
In response to a question about how this reflects on the fertility industry Dr. Wisot replied, "Most people understand that these are the actions of somebody who is way, way out…
According to a survey of 26 sperm banks reported in the July 2010 edition of Fertility and Sterility, sperm banks vary considerably in their practices of genetic screening of donors.
Cystic fibrosis carrier screening, chromosome analyses, and hemoglobin evaluations are performed on the majority of sperm donor applicants. Tay-Sachs disease carrier screening is performed on most donors with Jewish heritage…
One of the most disappointing scenarios is when a couple who has tried to conceive for a long time miscarries their hard-fought-for pregnancy. A study reported in the July 2010 issue of Fertility & Sterility shows that the prognosis for a subsequent healthy pregnancy is good.
They looked at 5,663 subfertile couples, of which 1,098 (19%) conceived spontaneously. Among…
Yes folks, the National Enquirer.
It's in the July 12th edition cover story on Kelly Preston's (Mrs. John Travolta) twin pregnancy at age 47.
Yes folks, twins at 47 and although they acknowledge it's an IVF pregnancy, they deny it's egg donation. OK.
Unfortunately she is still early and something has happened that has required her to…
That's a question I am frequently asked.
In an article in the June 21st issue of the medical journal US Weekly, "Baby After 40." they give examples of current and recent pregnancies as "Hollywood's 'miracle' moms beat the odds."
But can they beat the odds just because they are famous? I think not. For many of them the "miracle" is…
Selection of a treatment method for women over 40 whose main limitiation in conceiving is their age can be difficult. If they are in the "unexplained infertility" group with open tubes, no significant gynecologic problems and a partner with normal sperm parameters the common choices are to try injectable fertility drugs (COH) with artificial insemination (IUI) or in vitro fertilization…
Traditionally a two day period of abstinence has been recommended prior to ovulation or an IUI. A recent study in the March 2010 issue of Fertility & Sterility suggests that shorter period of absintence results in better pregnancy rates. In this study an ejaculatory abstinence period of less than 2 days before IUI produced the highest pregnancy rates per…
The process of egg freezing by vitrification has developed as a clinical technique just in the last few years. Now a study in the March 2010 edition of the medical journal Fertility & Sterility shows that it is very effective way of preserving an otherwise fertile woman's fertility potential for the future.
Nineteen women agreed to have their eggs…
For a long time we have been able to assess a man's sperm quality by looking at the number of sperm, the effective motility of the sperm and the shape of the sperm to evaluate a man's fertility potential. But we now know that what we can see only tells us part of the story. In recent years a lot…
