AI Article Synopsis
- * Male sterility, while not beneficial for individual plants, is essential in hybrid rice breeding systems, including the three-line and two-line methods.
- * Studying male sterility enhances insights into male reproductive processes and aids in the genetic enhancement of rice hybrids, making it crucial for both basic research and agricultural advancement.
Article Abstract
Male reproductive development is a complex and highly ordered phenomenon which demands comprehensive understandings of underlying molecular mechanisms to expand its scope for crop improvement. Genetic manipulation of male fertility/sterility is critical for crop hybrid breeding. Although male sterility is not a good trait for the plant itself, its wider application in hybrid rice breeding has made it valuable. The currently widely used male sterile line breeding systems mainly include the following: three-line hybrid rice based on cytoplasmic male sterility and two-line hybrid rice based on environmentally sensitive gene male sterility. The study of male sterility is an excellent thoroughfare to critically understand the regulatory mechanisms essential for the complicated male reproductive developmental process. The unique trait of male sterility also provides valuable resources and convenience for the genetic improvement of rice hybrids. Therefore, deeper and broader understandings about the genetic causes of male sterility are necessary for both basic studies and rice genetic improvement.

Background: The present study is a systematic review and meta-analysis aiming to investigate the effects of alcohol consumption on male sex hormones in humans.
Methods: We conducted searches on PubMed, Scopus, Science Direct, and Google Scholar from June 2020 to June 2022. We included observational studies (cohorts, case-controls, and cross-sectional studies) comparing FSH, LH, or testosterone levels in alcohol consumers versus non-consumers.

Background: Many studies in India and all over the world have focused on the psychological aspect of infertility in women, but only a few have explored it among men. To deal with psychological distress, sometimes, individuals may use maladaptive coping strategies which can further worsen the stress instead of reducing it.
Aim: To assess symptoms of depression, anxiety, stress, and various coping strategies adopted by men with infertility along with exploring their coping experiences.

Estrogen through its receptors, ERα and ERβ, regulate various aspects of spermatogenesis and male fertility. Since the sperm epigenome is an important contributing factor to male fertility, we evaluated the effects of estrogen signaling activation through the ERs on sperm DNA methylome in adult rats. Whole genome-bisulfite sequencing (WGBS) in caudal sperm DNA was performed.
