Androgen binding protein provides a mechanism for the accumulation of androgens within the Sertoli cells and its release into the lumen of the seminiferous tubules. From the lumen, ABP transports testosterone to the epididymis, where they mature and develop the potential for fertilization and motility. Physiological Functions of Estrogens:
Male and Female Reproductive System!
Changes in the human body: When a baby begins to grow, the different parts of its body such as the head, arms, legs and chest grow at different rates. For about the first 12 years of its life it goes through a phase of body enlargement and mental development.
During this phase its reproductive organs develop at a slower rate. At about 12 years of age, body enlargement slows down and certain other changes begin to appear. These changes prepare the body for sexual reproduction.
This phase is known as adolescence. During this phase, certain parts of the body change in appearance and the person also experiences new sensations such as extreme happiness, sadness, anger, insecurity, and so on.
All this is due to the beginning of the secretion of hormones from the ovary and testis. The age when this begins is called the age of sexual maturity puberty.
It varies from person to person. It is marked by the growth of thick hair in the armpits and pubic area. In males, facial hair begins to grow. The vocal cords become wide.
Therefore, the voice begins to deepen. The testes become active and begin to produce sperms. The penis and scrotim become larger.
In females the menstrual cycle begins and the breasts become enlarged. These changes are slow and take place over six years or so. They serve as signals identifiable by other individuals that sexual maturation is taking place.
From this period onwards sexual reproduction becomes a possibility as the body becomes capable of producing the specialized germ cells that are needed for sexual reproduction.
But childbearing and lactation milk secretion need the female reproductive organs and breasts to be fully developed. The male reproductive organs include the testes, seminal vesicles, penis and some associated glands such as the prostate gland.
The most important male reproductive organ is the testis, which produces sperms. There are two oval testes, each contained in a protective bag called scrotum or scrotal saclying outside the abdominal cavity. The scrotal sac can elongate and contract depending upon the body temperature and external temperature.
This is necessary because sperm formation occurs at a temperature lower than normal body temperature.
The testes produce sperms continuously from the stage of puberty onwards. Sperms from the testis pass through the sperm duct, known as vas deferens. The vas deferens runs interiorly up to the urinary bladder, from where it leads downward and is joined by a duct from the seminal vesicle.
The seminal vesicle is an elongated sac at the base of the urinary bladder. For each testis, there is one vas deferens and one seminal vesicle. The functions of a seminal vesicle are to store the sperms that have come from the testis and to secrete seminal fluid, or semen, in which the sperms float.
The sperm ducts from both sides join near the base of the urinary bladder, opening into a single tube called urethra Figure 6. This junction occurs inside the prostate gland.
The prostate gland adds its secretion to the seminal fluid.Reproductive System. The purpose of the reproductive system is to produce a new life.
Human bodies are made in a way that requires two partners, male and female, to participate in the act of conception. However, the most recent advancements in medical science can make this system obsolete, which can help humanity move onto the next step of evolution. We will now describe the human male reproductive system and female reproductive system in detail, one by one.
The Male Reproductive System: The human male reproductive system consists of the following organs: Testes, Scrotum, Epididymis, Vas deferens (or .
Reproductive System Research Essay Between the two reproductive systems, each contain their own function to provide for the human body. In the female reproductive system, the different parts include: the ovary, ovum, fallopian tube, uterus, cervix, vulva, and the vagina.
- The Reproductive System The male and female reproductive systems are different with both having specific roles. The Male Reproductive System ===== The main structures of the male reproductive system are the testes, the penis and several glands.
Human Reproductive System: Male and Female Reproductive System! Changes in the human body: When a baby begins to grow, the different parts of its body such as the head, arms, legs and chest grow at different rates.
For about the first 12 years of its life it goes through a phase of body enlargement and mental development.
The reproductive system involves a number of organs that work together to reproduce new life. There are a number of differences between the two systems within the genders, which will be addressed. Genetic material allows for a greater genetic fitness of the offspring in the reproductive system.
