Purpose: The diagnosis of children with disorders of sex development (DSD) requires a karyotype, different biochemical and radiological investigations in the context of a multidisciplinary team. The aim of this study was to compare the diagnostic accuracy of laparoscopy (L) versus ultrasonography (US) in the assessment of children with complex DSD.
Methods: We retrospectively examined the theatre database searching for children with DSD who underwent laparoscopic surgery from 1999 to 2011. The medical and radiological records were reviewed.
Results: Eighteen patients were identified. Age at diagnosis ranged from birth to 14 years (mean 2.5 years). There were seven patients with 46XY dysgenetic testicular DSD (4 mosaic Turner, 3 mixed gonadal dysgenesis), seven patients with 46XY non-dysgenetic testicular DSD (4 persistent Mullerian duct syndrome, 2 complete androgen insensitivity syndrome, one unknown), two patients with ovotesticular DSD, one patient with 46XX DSD (congenital adrenal hyperplasia) and one patient with 46XY DSD complete sex reversal. Fifteen underwent ultrasonography prior to laparoscopy. Both modalities identified Mullerian structures in seven (47 %) patients, in one (7 %) patient US and L confirmed the absence of Mullerian structures, while in six (40 %) patients there was discordance, with US failing to visualize pelvic Mullerian structures. In the last patient with 46XY non-dysgenetic testicular DSD, the rectum was thought to be a dilated uterus on ultrasonography.
Conclusions: Pelvic ultrasonography failed to identify Mullerian structures in 40 % of patients with complex DSD. On the contrary, laparoscopy allowed excellent visualization of pelvic structures and gonads in children with complex DSD.

Purpose: This study aimed to analyze the distribution and factors influencing anti-Müllerian hormone (AMH) levels among family-planning women of childbearing age in Beijing, China.
Patients And Methods: We collected the data of 3,236 family-planning women of childbearing age who underwent pre-pregnancy examinations at Xicheng District Maternal and Child Health Hospital in Beijing between October 2021 and July 2024. Collected data included age, education level, ethnicity, height, weight, and systolic and diastolic blood pressure.

Objective: This study aimed to investigate the possible mechanism through which acupuncture protects ovaries with Poor Ovarian Response (POR) in rats based on microRNA (miRNA).
Methods: Thirty-six SPF SD female non-pregnant rats aged 8 weeks were randomly divided into the blank group, model group, and acupuncture group, with 12 rats in each group. According to the group, the rats were given gavage of Tripterygium wilfordii polyglycosides suspension for 14 days to establish the model of POR, and then the rats were treated with acupuncture for 2 weeks, once a day, for 20 minutes.

The anti-Müllerian hormone (AMH) is a granulosa cell-derived hormone that has been associated with female fertility and reflects the population of growing follicles. This study aimed to evaluate the average concentration of AMH in Lipizzaner mares, as well as to determine the relationship between AMH concentration and follicle number and size. We also investigated the relationship between the age of mares and their AMH levels.

TGFβ family ligands are synthesized as precursors consisting of an N-terminal prodomain and C-terminal growth factor (GF) signaling domain. After proteolytic processing, the prodomain typically remains noncovalently associated with the GF, sometimes forming a high-affinity latent procomplex that requires activation. For the TGFβ family ligand anti-Müllerian hormone (AMH), the prodomain maintains a high-affinity interaction with its GF that does not render it latent.
