Noninvasive electrophysiological imaging identifies 4D uterine peristalsis patterns in subjects with normal menstrual cycles and patients with endometriosis.

Throughout the menstrual cycle, spontaneous mild contractions in the inner layer of the uterine smooth muscle cause uterine peristalsis, which plays a critical role in normal menstruation and fertility. Disruptions in peristalsis patterns may occur in women experiencing subfertility, abnormal uterine bleeding, ovulatory dysfunction, endometriosis, and other disorders. However, current tools to measure uterine peristalsis in humans have limitations that hamper their research or clinical utilities.

Imaging of the Vagina: Spectrum of Disease with Emphasis on MRI Appearance.

The vagina is a median fibromuscular structure of the female reproductive system that extends from the vulva inferiorly to the uterine cervix superiorly. As most vaginal lesions are detected at gynecologic examination, imaging performed for nongynecologic indications can frequently cause concomitant vaginal pathologic conditions to be overlooked. The vagina is often underevaluated at routinely performed pelvic transvaginal US because of a narrow scan area and probe positioning.

Association between arthritis treatments and ovarian reserve: a prospective study.

Research Question: How do anti-Müllerian hormone (AMH) concentrations in women with and without arthritis compare? Is there an association between AMH and arthritis drug regimen?

Design: In this prospective cohort study, AMH was measured at two time points (T and T) in 129 premenopausal women with arthritis. AMH at T was compared with that from a bank of serum samples from 198 premenopausal women without arthritis. Primary outcomes were: (i) diminished ovarian reserve (DOR) (AMH <1.

Photoacoustic laser effects in live mouse blastocysts: pilot safety studies of DNA damage from photoacoustic imaging doses.

Objectives: To investigate the laser safety of photoacoustic imaging. In photoacoustic imaging, a pulsed laser of several nanoseconds is used to illuminate biological tissue, and photoacoustic waves generated by optical absorption are used to form images of the tissue. Photoacoustic imaging is emerging in clinical applications; however, its potential use in reproductive medicine has yet to be reported.
