Hormones. Progesterone and estrogen are the two main sexual hormones in a female dog and can be produced from the ovaries or the adrenal glands. Estrogen prepares the reproductive tract for breeding, assists in the motility of the female and male gametes, and affects her behavior to make her more attractive to males.
What are three accessory glands of the male reproductive system?
They are:
- the seminal vesicles
- the prostate gland
- the bulbourethral glands
Which glands start puberty in males?
Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction.It is initiated by hormonal signals from the brain to the gonads: the ovaries in a girl, the testes in a boy. In response to the signals, the gonads produce hormones that stimulate libido and the growth, function, and transformation of the brain, bones, muscle ...

Which glands are present only in males or females name them?
The testes are found in the male reproductive system only. This endocrine gland occurs in them in a pair and is oval-shaped, it produces sperms and the testosterone hormone. This gland is absent in females. Another gland found only in men are the prostate glands, which is functional in producing some part of the semen.
Which hormone is common in both male and female?
1.2. Generally, females and males have the same hormones (i.e., estrogens, progesterone, and testosterone), but their production sites, their blood concentrations, and their interactions with different organs, systems, and apparatus are different [29].
What are the similarities of male and female endocrine glands?
In humans, all of the endocrine glands in the body are very similar in size and shape between males and females. These glands include the pineal gland, the hypothalamus, the pituitary gland, the thyroid gland, the thymus gland, the pancreas, and the adrenal glands.
Which gland is different in males and females?
All the endocrine glands that are present in males and females are the same except for the gonads. In males, it is the testis and in females, it is the ovaries.
Which gland is also called the master gland?
The pituitary glandThe pituitary gland is sometimes called the "master" gland of the endocrine system because it controls the functions of many of the other endocrine glands. The pituitary gland is no larger than a pea, and is located at the base of the brain.
Is oxytocin a female hormone?
Oxytocin is a natural hormone that manages key aspects of the female and male reproductive systems, including labor and delivery and lactation, as well as aspects of human behavior. Your hypothalamus makes oxytocin, but your posterior pituitary gland stores and releases it into your bloodstream.
Which gland is both endocrine and exocrine?
The pancreasThe pancreas has both an endocrine and an exocrine function.
Is the endocrine system the same in the male and female?
The endocrine glands are the same in both male and females except for the reproductive glands, the testes in males and ovaries in females.
Do females have a pituitary gland?
In cranial magnetic resonance imaging (MRI), the pituitary gland of women is greater in size compared to men [1]. This may be due to the hypertrophy and hyperplasia of lactotroph cells of the anterior pituitary gland during pregnancy.
Why do hormones involve in the male and female reproductive system?
They help develop and maintain female sex characteristics and play an important role in fertility, pregnancy, and the menstrual cycle. Male reproductive hormones, such as testosterone, help develop and maintain male sex characteristics and help make sperm in the testes.
Which of these reproductive hormones plays a role in the production of both female and male gametes?
In both males and females, FSH stimulates gamete production and LH stimulates production of hormones by the gonads.
What are the hormones involved in the male and female reproductive system explain each of its function?
The main reproductive hormones are oestrogen and testosterone. Oestrogen causes eggs to mature in ovaries once a girl hits puberty. These are then released at regular intervals during the menstrual cycle. Testosterone stimulates sperm production in males.
Are reproductive hormones in male similar to the reproductive hormones present in female?
Male hormones The sex hormones of the male follow a much simpler pattern than do those of the female, although the same principle of interaction exists between the pituitary gland and the gonads.
What are the reproductive structures of males and females?
Male and female reproductive structures and their functions. The gonads are the precursors of the genitalia in males that mostly include external (penis, scrotum, epididymis, and testes) and in females that mainly include internal (vagina, uterus, fallopian tubes, cervix, and ovary) organs; genitalia allow males and females to mate, ...
What are the internal structures of the female reproductive system?
Internal female reproductive structures include ovaries, oviducts, the uterus, and the vagina. Mons pubis: A round, fatty area that overlies the pubic symphysis. Clitoris: A structure with erectile tissue that contains a large number of sensory nerves and serves as a source of stimulation during intercourse.
What are the functions of the male reproductive system?
The functions of the male reproductive system include producing and transporting sperm, ejaculating sperm into the female reproductive tract, and producing and secreting male hormones. The organs of the male reproductive system are specialized for three primary ...
What is the structure of the uterus?
Uterus: A structure about the size of a woman’s fist. It supports the developing embryo and fetus during gestation. The cervix is the lowermost portion of the uterus. Vagina: A muscular tube that serves as a common tube for intercourse, birth canal, and passing menstrual flow.
Where is the epididymis located?
Epididymis: Located at the back of the testis and connects it to the vas deferens. This is where the sperm fully matures and becomes motile, and it functions to store and carry sperm. Testis: The location for testosterone production. The coiled collection of tubes within the testes are the seminiferous tubules.
Which hormone is produced primarily in the male testes and responsible for the development of male secondary sex characteristics?
It also provides a medium for sperm motility. Testosterone: a steroid hormone produced primarily in the male testes and responsible for the development of male secondary sex characteristics. Vulva: consists of the female external genital organs. Primitive Gonads: formed by the proliferation of germ cells.
Where are the vestibular glands located?
Greater vestibular glands: Found at the sides of the vaginal opening and provide lubrication during intercourse. Breast: Consists of mammary glands and fat. It produces and delivers milk. Internal structures:
What are the internal and external reproductive organs?
The female reproductive system is comprised of both internal and external reproductive organs that both enable fertilization and support embryonic development. Structures of the female reproductive system include: Labia majora: Larger lip-like external structures that cover and protect other reproductive structures.
What are the reproductive systems?
The reproductive system is susceptible to a number of diseases and disorders. These are of varying degrees of detriment to the body. This includes cancer that can develop in reproductive organs such as the uterus, ovaries, testicles, and prostate.
What are the internal and external structures of the reproductive system?
The primary reproductive organs of either system are called gonads (ovaries and testes) and these are responsible for gamete (sperm and egg cell) and hormone production. Other reproductive structures and organs are considered secondary reproductive structures and they aid in the growth and maturation of gametes and offspring.
What is the function of the epididymis?
Epididymis: System of ducts that receive immature sperm from the testes. The epididymis functions to develop immature sperm and house mature sperm.
How are gametes produced?
Gametes are produced by a two-part cell division process called meiosis. Through a sequence of steps, replicated DNA in a parent cell is distributed among four daughter cells. Meiosis produces gametes that are considered haploid because they have half the number of chromosomes as the parent cell.
What is the process of producing sperm cells?
Spermatogenesis. The production of sperm cells is known as spermatogenesis . Stem cells develop into mature sperm cells by first dividing mitotically to produce identical copies of themselves and then meiotically to create unique daughter cells called spermatids.
What are the disorders of the female reproductive system?
Disorders of the female reproductive system include endometriosis —a painful condition in which endometrial tissue develops outside of the uterus—ovarian cysts, uterine polyps, and uterine prolapse.
