Progesterone, as a female hormone, plays an important role in the physiological function and pregnancy maintenance in women. Recent studies show that progesterone and its receptor are also involved in male reproduction, and its receptor mRNA exists in male sexual glands. It is believed that progesterone, binding to its receptor, can regulate spermatogenesis and improve the fertilization of sperm, while the sperm from those with oligospermia, asthenozoospermia, teratospermia or unexplained infertility exhibit a low fertility due to the deficient expression of the progesterone receptor and insensitive reaction to progesterone. This review focuses on the progress in the studies of progesterone and its receptor in male reproduction.

Breast cancer (BrCa) is a complex and heterogeneous disease with diverse molecular subtypes, leading to varied clinical outcomes and posing significant treatment challenges. The increasing global burden of BrCa, particularly in low- and middle-income countries, underscores the urgent need for more effective therapeutic strategies. The androgen receptor (AR), expressed in a substantial proportion of breast cancer cases, has emerged as a potential biomarker and therapeutic target.

Purpose: To study the association between clinicopathologic characteristics of ductal carcinoma in situ (DCIS) and risk of subsequent invasive breast cancer (IBC).
Methods: We conducted a case-control study nested in a multicenter, population-based cohort of 8175 women aged ≥ 18 years with DCIS diagnosed between 1987 and 2016 and followed for a median duration of 83 months. Cases (n = 497) were women with a first diagnosis of DCIS who developed a subsequent IBC ≥ 6 months later; controls (2/case; n = 959) were matched to cases on age at and calendar year of DCIS diagnosis.

Female sexual behavior is a naturally rewarding activity that plays an important role in reproduction and species survival. For female rats, regulating the timing of sexual interactions is essential for optimizing mating satisfaction and enhancing the physiological conditions needed for successful fertilization. So far, traditional research on female sexual behavior has relied on a limited set of behavioral parameters, which has certain shortcomings.

Breast cancer (BC) patient-derived xenografts (PDX) are relevant models for precision medicine. However, there are no collections derived from South American BC patients. Since ethnicity significantly impacts clinical outcomes, it is necessary to develop PDX models from different lineages.

The benefit of adjuvant chemotherapy (CT) for hormone receptor-negative T1a and T1bN0M0 breast cancer remains uncertain. Our study was to explore prognostic value and identify candidates of adjuvant CT for these patients. The data of hormone receptor-negative T1a and T1bN0M0 breast cancer patients were extracted from the Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2015.
