FSH male target Testes (sertoli cells)
FSH male primary action Sertoli cell formation
FSH release is controlled by the feedback of inhibin from the testicle. The target organs for FSH ;;;FSH participates in protein synthesis and the initiation of spermatogenesis at the level of the seminiferous tubules.FSH binds to the Sertoli cells of the seminiferous tubules, increases cAMP and protein synthesis, androgen binding in the tubules, etc. Regulated by inhibin produced by the Sertoli cells. Sertoli cells secrete proteins that are important to spermatogenesis and have been called the director cells of spermatogenesis. They comprise the blood-testis barrier.

Testosterone and other androgens are secreted by the
http://www.urology-textbook.com/male-hormones-testosterone.html
Testosterone is a steroid hormone from the androgen group that is primarily secreted in the testes. It is the principal male sex hormone and is largely responsible for male growth and development. Men care about testosterone because deficiencies in the hormone can lead to muscle weakness or sexual disorders, such as erectile dysfunction. While testosterone replacement therapy is possible, it is not an option for all men, and should only be considered under the guide of a health-care professional

7;average cycle of 28 days, describe each of the three phases of the uterine cycle
gynaeonline.com/uterine_cycle.htm
Phases of Menstrual cycle
The day count for menstrual cycle begins on the first day of menstruation when blood starts to come out of the vagina. In this section, the length of menstrual cycle has been assumed to be 28 days (which is the average among women). The entire duration of a Menstrual cycle can be divided into four main phases:

1.Menstrual phase (From day 1 to 5)
2.Follicular phase (From day 1 to 13)
3.Ovulation phase (Day 14)
4.Luteal phase (From day 15 to 28)

Menstrual phase (day 1-5)
Menstrual phase begins on the first day of menstruation and lasts till the 5th day of the menstrual cycle. The following events occur during this phase:

•The uterus sheds its inner lining of soft tissue and blood vessels which exits the body from the vagina in the form of menstrual fluid.
•Blood loss of 10 ml to 80 ml is considered normal.
•You may experience abdominal cramps. These cramps are caused by the contraction of the uterine and the abdominal muscles to expel the menstrual fluid.
Ovulation phase (day 14)
On the 14th day of the cycle, the pituitary gland secretes a hormone that causes the ovary to release the matured egg cell. The released egg cell is swept into the fallopian tube by the cilia of the fimbriae. Fimbriae are finger like projections located at the end of the fallopian tube close to the ovaries and cilia are slender hair like projections on each Fimbria.
Luteal phase (day 15-28)
This phase begins on the 15th day and lasts till the end of the cycle. The following events occur during this phase:

•The egg cell released during the ovulation phase stays in the fallopian tube for 24 hours.
•If a sperm cell does not impregnate the egg cell within that time, the egg cell disintegrates.
•The hormone that causes the uterus to retain its endometrium gets used up by the end of the menstrual cycle. This causes the menstrual phase of the next cycle to begin.

5 Events of the Menstrual Cycle
http://www.livestrong.com/article/208669-what-are-the-5-events-of-the-menstrual-

The ovarian cycle is regulated by the interaction of hormones produced by the hypothalamic-pituitary-gonad. There are five main hormones involved in this process: GnRH, FSH, LH, estradiol and progesterone.

The cycle is divided into three phases: follicular, ovulation, luteal phase.

Describe the cycle, day 1 designating the first day of bleeding. Throughout the cycle will produce a series of changes in levels of gonadotropins and ovarian hormones 1 .. Each hormone has a different function.

- The FSH is the hormone that makes the recruitment and growth of ovarian follicles and the willLesson of the dominant follicle. Acts on the granulosa cells and has a half life of 4 hours.
- The LH acts on interstitial cells and stromal way that induces the production of steroids and triggers ovulation. It has a half-hour half-life.

The steroids synthesized by the action of gonadotropins are estradiol and progesterone. Occur at the level of hair and body lúteo. 3 .

Cycle regulation

During the first week of the cycle begins recruitment of the cohort of follicles. FSH in the first week gradually increases, the follicles are growing at the same time that increase the number of receptors on the granulosa to this hormone, the same is true for the LH receptor level teca. 2 .cells The follicles produce estradiol at this time in small quantities.

In the second week all of the cohort follicles continue to grow, the FSH receptors of granulosa increase so that the granulosa is transforming androgens into estradiol resulting in a significant increase this. This increase produces a negative feedback onFSH decreased significantly. Thus the dominant follicle is selected. The remaining follicles will degenerate by a process called atresia.

After selecting the dominant follicle, the concentration of Estradiol is increasing, so that is a peak 72 hours before the ovulación. 1 .This high concentration of estradiol produces a positive feed back which leads to the occurrence of increased production of FSH and LH leading to a peak of both hormones.
36 hours after the LH peak occurs ruptured Graafian follicle releases the oocyte and resulting in ovulation.

Produced once ovulation the granulosa cells are arranged to form a new gland the corpus luteum. The corpus luteum will 3 .different ways depending on whether or not fertilization occurs.

While the stages are produced ovary, the endometrium undergoes cyclic changes in thickness and texture, related to levels of estrogen and progesterone. 5 .

Cyclical changes of the endometrium during the menstrual cycle result in several phases: proliferative, secretory andmenstrual. These stages are developed continuously, so that no sudden change between ellas 6 ..
