What is adenomyosis? It's linked to endometriosis! Adenomyosis is when your endometrial tissue exists within and grows into the uterine wall.

"Endometriotic lesions can also invade the muscle of the uterus. The condition is then called adenomyosis...That retrograde menstruation cannot be the only pathophysiology is also demonstrated by premenarcheal females having been diagnosed with endometriosis. On the other age extreme, endometriosis, widely believed only to be a disease of reproductive years, has also been diagnosed in postmenopausal women.

Though most frequently diagnosed during reproductive years, all of these unexpected observations have only further confused the evolution of a single, logical hypothesis for the occurrence of endometriosis. A very recent study, indeed, implied the existence of a peritoneal immunologic tolerance-niche in women with endometriosis that allows for implantation of endometrial cells which in most women is not allowed by the female immune system."

"One of the most frequently heard cliches permeating medical practice in the U.S. is the notion that medical care is to be determined in the interaction of patient and physician. The Code of Medical Ethics from the American Medical Association (AMA) in its first paragraph, indeed, defines the practice of medicine as “embodied in the clinical encounter between a patient and a physician (and) as a fundamentally moral activity that arises from the imperative to care for patients and to alleviate suffering.”
Moreover mederal law strictly defines who is considered a “health care provider “ and/or “practitioner” (and, therefore, is entitled to provide medical care) as a “a doctor of medicine or osteopathy, podiatrist, dentist, chiropractor, clinical psychologist, optometrist, nurse practitioner, nurse-midwife, or a clinical social worker who is authorized to practice by the State and performing within the scope of their practice as defined by State law, or a Christian Science practitioner."

"At most only a small number of subjects in female medicine are surrounded by as much “mystique” as the condition known as endometriosis. Because endometriosis clinically affects women especially during reproductive years, it is erroneously widely perceived as mostly a reproductive disease, causing infertility and, on occasion, also causing pelvic pain and several other symptoms. Endometriosis is, however, a much more complex condition than that, and in many women because of significant symptoms greatly affects quality of life."

"Dr Barad was very kind and gentle. My retrieval was only my second time meeting him and he instantly made me feel comfortable.

Dr. Christy the anesthesiologist was so funny and talkative. She explained what she was going to do every step of the way but also was definitely trying to ease my kid with distractions talking about vacay places etc."

🔬 Time for more research images! 🔬

Using a specialized imaging technique known as confocal microscopy, the CHR-Rockefeller collaboration began to examine human blastocysts such as this in which the embryo is labeled with specific antibodies to a portion of each chromosome in the human genome.

In green with yellow blobs on it is the zona pellucida that is known to protect the early embryo from its environment. Within the zona, the blue denotes each of the nuclei in the blastocyst and note that each nucleus has a series of fine spots or foci that appear pink.

These foci represent centromeres, specific regions on each of the 46 chromosomes and by analyses like this, our work is continuing to decipher exactly where and when the chromosomes get positioned during development.

Check out the latest edition of The Voice! Today we're talking about PRP!

"Greek investigators were the first to report on intraovarian PRP injections in 2016, claiming restauration of ovarian function and menstruation in allegedly perimenopausal and menopausal women with a history of one year of amenorrhea. Published experience with intraovarian PRP treatments has unfortunately largely remained restricted to anecdotal experiences and, at best, to small case series. Yet, as with so many other “add-ons” to IVF in the last two decades, the use of PRP has proliferated among IVF centers with none reporting truly interpretable results. Nevertheless, the procedure is widely advertised by many IVF centers, often under the obviously misleading, though equally obviously “s*xy” name "ovarian rejuvenation.”

New in the October Voice: DHEA May Support Fetal Brain Development.

"We know that the fetus produces a large amount of DHEA in the adrenal glands – enough to increase the amount of DHEA in the mom’s body during pregnancy, in fact. This extra DHEA is primarily taken up by the placenta and converted into an estrogen, which helps the uterus and placenta grow with the baby to maintain a healthy pregnancy. Doctors think, however, that a part of this additional DHEA is also used to support fetal brain development during pregnancy.2 The mechanism is not very well understood, but scientists are working for a better understanding. A review of animal studies, for example, suggested that DHEA may regulate the effects of another steroid hormone, glucocorticoids, necessary for normal brain development."

"After age 35, phenotype D patients, uniformly, and uniquely for PCOS, are characterized by abnormally low androgen levels, - a crucially important and previously unknown finding for the understanding of the D-phenotype; but also for the understanding of its treatment resistance to IVF and the required treatment to overcome this resistance. Normal androgen levels are essential for normal follicle maturation. Women with low androgen levels, at certain ages often become infertile. CHR’s⁠
investigators, consequently, hypothesized that this developing hypo-androgenism in PCOS phenotype D patients after age 35 must be the explanation for their treatment resistance to standard IVF." ⁠

It's time for more research images! 😊 Research at the CHR continues to uncover fundamental aspects
of early human development that have been implicated in the
failure of some embryos to proceed al the way to blastocyst
while others cannot seem to get past the early cleavage stages.

🥚 Image 1 is a three-dimensional rendering of a field of 2
and 3 cell mouse embryos that has been reconstructed from a
series of optical image slices known as a Z-stack.

🥚 Image 2 was taken at the CHR as part of a study being conducted on the function of granulosa cells and how
it may change as women undergo aging. What you see in red are important structures within the cells that are known as actin filaments, shown here to form dense fibers acting very much like
the fibers that control contraction of muscles.

🥚 Image 3 shows the three dimensional reconstruction of a portion of the cumulus oocyte complex viewed with a confocal microscope after staining a fixed specimen to delineate sites of cell-cell contact (red), nuclei (yellow) and outer cell boundaries (blue).

The September Voice is out! This edition we're covering PCOS Awareness Month!

"As a “syndrome,” the Polycystic O***y Syndrome (PCOS) identifies not as a single disease but as an amalgam of
conditions, so-called phenotypes, that share common clinical denominators.... Though, in general and in infertility populations, A, B, and C patients represent a large majority of all PCOS cases, to everybody’s surprise, PCOS patients at CHR represented
these major phenotypes in only less than 5% of cases, with over 95% being of phenotype D."

We love our research images! Image 1 shows a human blastocyst comprised of more than 100 cells on day 5 of culture. Genetic testing of this embryo revealed abnormalities in s*x chromosomes and it was then submitted to one of our research studies on genetic composition. Each nucleus is labeled in blue using a DNA binding dye and the red linear patterns reveal the cell boundaries for each of the individual cells of the blastocyst.

After digital image processing, we can view the same embryo in a somewhat different light as shown in Image 2. Here many
more discrete features of the blastocyst are revealed that allow our investigations to assign more specific functions and
patterns to embryos in the course of CHR research activity.

As for image 3, an 8-cell mouse embryo is shown here using conventional fluorescence microscopy; note the difference in clarity when compared to the two confocal images. The main feature in this embryo is shown at the twelve-noon position as the organization of a single mitotic spindle indicates a cell that was in the active state of dividing at the time the embryo was prepared for imaging.
