Objective: To assess sexual function in women with spontaneous 46,XX primary ovarian insufficiency after at least 3 months of a standardized hormone replacement regimen.
Design: Cross-sectional cohort, controlled.
Setting: National Institutes of Health Clinical Research Center.
Patient(s): Women with primary ovarian insufficiency (n = 143) and regularly menstruating controls (n = 70).
Intervention(s): Self-administered questionnaires, 100 microg/day E(2) patch, oral medroxyprogesterone acetate 10 mg for 12 days each month for patients.
Main Outcome Measure(s): Derogatis Interview for Sexual Function Self-Report (DISF-SR).
Result(s): Women with primary ovarian insufficiency had significantly lower DISF-SR composite scores compared with control women. Their serum total testosterone levels were significantly correlated with DISF-SR composite score, although this accounted for only 4% of the variance in this measure. Patients with testosterone levels below normal tended to have lower DISF-SR composite scores. Of patients with primary ovarian insufficiency, 9 of 127 (7%) scored below the second percentile on the composite sexual function score, compared with 1 of 49 control women (2%).
Conclusion(s): As assessed by the DISF-SR, sexual function is in the normal range for most young women with 46,XX spontaneous primary ovarian insufficiency who are receiving physiologic E(2) replacement. However, as a group, these young women score significantly lower on this sexual function scale than control women.

In mammals, differentiation of germ cells is crucial for sexual reproduction, involving complex signaling pathways and environmental cues defined by the somatic cells of the gonads. This review examines the long-standing model positing that all-trans retinoic acid (ATRA) acts as a meiosis-inducing substance (MIS) in the fetal ovary by inducing expression of STRA8 in female germ cells, while CYP26B1 serves as a meiosis-preventing substance (MPS) in the fetal testis by degrading ATRA and preventing STRA8 expression in the male germ cells until postnatal development. Recent genetic studies in the mouse challenge this paradigm, revealing that meiosis initiation in female germ cells can occur independently of ATRA signaling, with key roles played by other intrinsic factors like DAZL and DMRT1, and extrinsic signals such as BMPs and vitamin C.

Purpose: To compare the erectile and urinary functions of ventral and dorsal onlay buccal mucosal graft (BMG) urethroplasty in the management of proximal bulbar urethral strictures (PBUS) in sexually active men.
Patients And Methods: We retrospectively included patients with primary non-traumatic PBUS who were treated with (BMG) urethroplasty at our department between March 2019 and March 2023 either ventral or dorsal approaches. Patients were assessed at 3- and 12-months postoperatively for urinary and erectile functions.

Adult males and females have markedly different body composition, energy expenditure, and have different degrees of risk for metabolic diseases. A major aspect of metabolic regulation involves the appropriate storage and disposal of glucose and fatty acids. The use of sophisticated calorimetry, tracer, and imaging techniques have provided insight into the complex metabolism of these substrates showing that the regulation of these processes varies tremendously throughout the day, from the overnight fasting condition to meal ingestion, to the effects of physical activity.

The great diversity of specialist plant-feeding insects suggests that host plant shifts may initiate speciation, even without geographic barriers. Pheromones and kairomones mediate sexual communication and host choice, and the response to these behaviour-modifying chemicals is under sexual and natural selection, respectively. The concept that the interaction of mate signals and habitat cues facilitates reproductive isolation and ecological speciation is well established, while the traits and the underlying sensory mechanisms remain unknown.

TBC1D20 deficiency causes Warburg Micro Syndrome in humans, characterized by multiple eye abnormalities, severe intellectual disability, and abnormal sexual development, but the molecular mechanisms remain unknown. Here, we identify TBC1D20 as a novel Rab11 GTPase-activating protein that coordinates vesicle transport and actin remodeling to regulate ciliogenesis. Depletion of TBC1D20 promotes Rab11 vesicle accumulation and actin deconstruction around the centrosome, facilitating the initiation of ciliogenesis even in cycling cells.
