Abstract
Local estrogen therapy has been explored as an alternative to conventional testosterone therapy in children requiring urethroplasty for hypospadias. Our objective is to evaluate if preoperative estrogen stimulation reduces post-urethroplasty complications and enhances penile dimensions. A systematic search was conducted on various databases, selecting only randomized controlled trials (RCTs) that tested estrogen on hypospadias patients under 18 years. Articles underwent sorting following PRISMA guidelines and bias risk was assessed using the JBI clinical appraisal tool for RCTs. Out of 607 screened records, 10 underwent full-text review, and 4 randomized controlled trials (RCTs) were selected for analysis. The total patient cohort across studies was 387 with 174 in the estrogen group. All studies utilized topical estrogen, but in different formulations and timings. Prudence is necessary for interpreting results due to variations in formulation, timing, and hypospadias type across studies. Limited by a small number of studies and outcome presentation non-uniformity, the review suggests no change in penile dimensions or postoperative complications with topical estrogen. Further research is needed to explore wound-healing properties of estrogen in hypospadias through animal and human studies.Registration and protocol: Registered in Prospero CRD42024502183.

Abstract
The penis is a complex organ with a development cycle from the fetal stage to puberty. In addition, it may suffer from either congenital or acquired anomalies. Penile surgical reconstruction has been the center of interest for many researchers but is still challenging due to the complexity of its anatomy and functionality. In this review, penile anatomy, pathologies, and current treatments are described, including surgical techniques and tissue engineering approaches. The self-assembly technique currently applied is emphasized since it is considered promising for an adequate tissue-engineered penile reconstructed substitute.

Biomed Pharmacother 2018; 109:621-628.

Abstract
Aminophenols, which are widely used as components of hair dye and medicine, may function as environmental endocrine disruptors by regulating the proliferation of endocrine-related cancers. Estrogen receptor α (ERα) is a key regulator of breast cancer. Recently, it was found that ERα may also participate in the transformation and progression of thyroid tumors, but its interaction with aminophenols and its function in thyroid tumors is not clear. In this study, the transcription factor activity of ERα in BHP10-3 cells (a thyroid tumor cell line) was examined using luciferase assays. The promoter recruitment of ERα was examined using chromatin co-precipitation (ChIP). Additionally, in an in vivo study, BHP10-3 cells were transplanted into nude mice. Upon administration of aminophenols, the transcription factor activity of ERα was significantly increased in BHP10-3 cells, and the recruitment of ERα to the promoter of its target gene was increased. Aminophenols enhanced the in vitro and in vivo proliferation of BHP10-3 cells. By discovering that aminophenols induce the onco-promoting activity of ERα, our study extends the understanding of the function of aminophenols and suggests that ERα is a potential therapeutic target for the treatment of thyroid tumors.
