Penis

The penis serves a dual role in sexual reproduction and urination. It consists of three main regions: the glans penis, the body, and the root, each with distinct functions and unique anatomical features.
Anatomy of the Penis
The glans penis, or the head, is the terminal part of the penis and houses the external urethral orifice, the exit point for urine and semen. Covered by the prepuce, or foreskin, the glans is noted for its sensitivity and plays a key role in sexual pleasure. The body of the...

Development of the Sexual Organs in the Embryo and Fetus

Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the male...
Gene Duplication and Divergence02:37

Gene Duplication and Divergence

The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was  generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are characterized.
