Chromosomal abnormalities can occur during fertilization impacting the development of the male reproductive system. The genotype of the male consists of a Y chromosome paired with an X chromosome. Female sex is determined by the absence of a Y chromosome. Some individuals are male who have the XX male syndrome and androgen insensitivity ...
Male reproductive system. The male reproductive system is a series of organs located outside the body and around the pelvis region of a male that contribute towards the reproduction process. The primary direct function of the male reproductive system is to provide the male sperm for fertilization of the ovum. [3] Penile shrinkage due to low ...
This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females.
The female reproductive system has two functions: The first is to produce egg cells, and the second is to protect and nourish the offspring until birth. The male reproductive system has one function, and it is to produce and deposit sperm. Humans have a high level of sexual differentiation.
The ejaculatory ducts (ductus ejaculatorii) are paired structures in the male reproductive system. [1] Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle. [2] They pass through the prostate, and open into the urethra above the seminal colliculus.
Successful reproduction typically involves sexual intercourse between a healthy, sexually mature and fertile male and female. [1] Because of ejaculation during intercourse, the male reproductive system deposits semen containing sperm into the female reproductive system, which can result in the fertilization of an ovum, to form a zygote.

Each crus represents the tapering, posterior fourth of each corpora cavernosa penis; the two corpora cavernosa are situated alongside each other along the length of the body of penis while the two crura diverge laterally in the root of penis before attaching firmly onto either ischial ramus at their proximal end.
A sex organ, also known as a reproductive organ, is a part of an organism that is involved in sexual reproduction. Sex organs constitute the primary sex characteristics of an organism. Sex organs are responsible for producing and transporting gametes , as well as facilitating fertilization and supporting the development and birth of offspring.
