Periodic discharge of blood, mucus, and epithelia cell from the uterus
Menstruation
Is the beginning of menstruation to the beginning of the next menstruation
Menstrual cycle
Is the first menstruation in women
Menarche
Is a severe pain during menstruation
Dysmenorrhea
Is the complete bleeding at completely irregular interval
Metrorrhagia
Is the excessive bleeding during menstruation
Menorrhagia
Is the absence of menstruation leading to pregnancy
Amenorrhea
Is the end of menstruation/cessation of menstruation
A
Menopause
A female hormone that is produced by the ovaries. It helps control and guide sexual development, including the physical changes associated with puberty
Estrogen
A hormone that helps to regulate your cycle. But its main function is to help thicken the lining of the uterus to prepare for a fertilized egg.
Progesterone
The mean age for menarche
12.87 years or 1-3 years after breast budding
is actually the end of an arbitrary defined menstrual cycle
Menses
The menstrual phase varies in length for most women
Ave period: 5 days
Ave cycle: 28 days
Normal blood loss: 50cc
Is the hormonal process a woman’s body goes through each month to prepare for a possible pregnancy
Menstrual cycle
a sign that your body is working normally
Regular menstrual periods in the years between puberty and menopause
For menstrual cycle to be complete, all four structures must contribute their part. Therefore, inactivity of any parts results in an incomplete or ineffective cycle
-hypothalamus
-pituitary gland
-ovaries
-uterus
Produces GnRH or Gonadotropin Releasing Hormone to stimulate the anterior Pituitary gland
Hypothalamus
Secretes gonadotropins (FSH and LH): stimulates the ovary (estrogen and progesterone) - if estrogen/progesterone increase in blood vessels, this gives positive feedback to the hypothalamus to decrease all hormones
Anterior Pituitary Gland
After an upsurge of LH, the graafian follicle raptures and the ovum is set free from the ovary
Ovulation
After an upsurge of LH, the graafian follicle raptures and the ovum is set free from the ovary called ovulation and swept into an open end of a fallopian tube, the FSH has done its work and now decreases its amount. It occurs approximately on the 14th day before the onset of the next menstrual cycle.
Ovaries
The ovulation happens at the midpoint of a 28-day cycle
If the cycle is only 20 days long 20-14=6 day of ovulation not the 10th or middle day
What happens if conception does not occur?
the unfertilized ovum atrophies after 4 days and the corpus luteum remain for only 8-10 days and regresses. Stimulation from the hormones produced by the ovaries causes specific monthly effects on the uterus and uterine changes occur during the menstrual cycle
If conception occurs, the fertilized ovum implants on the endometrium of the uterus, the corpus luteum remains throughout
Uterus
Menstrual flow is composed of:
-blood from ruptured capillaries
-mucin from the glands
-fragments of the endometrial tissue
- the microscopic, atrophied, unfertilized ovum
Indications of Ovulation
There is a slight drop in temperature one day prior to ovulation with a one-half to one degree rise in temperature at ovulation that remains elevated for 12-14 days.
Cervical mucus is abundant, watery, clear, and more alkaline. Cervical Os dilates slightly, softens and rises in the vagina
Presence of Spinnbarkeit and ferning under microscope
Egg-white stretchiness of cervical mucus
Spinnbarkeit
is the monthly hormonal cycle a female’s body goes through to prepare for preganancy
Menstrual cycle
is counted from the first day of your period up to the first day of your next period. Your hormone levels usually change throughout the menstrual cycle and can cause menstrual symptoms
menstrual cycle
Four main phases of the menstrual cycle
- menstruation
- follicular phase
- ovulation
- luteal phase
is the elimination of the thickened lining of the uterus (endometrium) from the body through the vagina
Menstruation
contains blood, cells from the lining of the uterus (endometrial cells) and mucus
menstrual fluid
What is the average length of a period?
between three days and one week
starts on the first day of menstruation and ends with ovulation. Prompted by the hypothalamus, the pituitary gland releases follicle stimulating hormone (FSH)
Proliferative/ follicular phase
This hormone stimulates the ovary to produce around five to 20 follicles (tiny nodules or cysts) which bead on the surface
Follicle stimulating hormone (FSH)
This can occur around day 10 of a 28 day cycle
Proliferative/ follicular phase
The growth of the follicles stimulates______ to thicken in preparation for possible pregnancy
lining of the uterus
is the release of a mature egg from the surface of the ovary. This usually occurs mid-cycle, around two weeks or so before menstruation start
Ovulation
During this phase, the developing follicle causes a rise in the level of estrogen. The hypothalamus in the brain recognizes these rising levels and releases a chemical called gonadotrophin-releasing hormone (GnRH)
follicular phase
This hormone prompts the pituitary gland to produce raised levels of luteinising hormone (LH) and FSH
gonadotrophin-releasing hormone (GnRH)
The life span of the typical egg is only around ____ Unless it meets a sperm during this time, it will die.
24 hours.
During ovulation, the egg bursts from its follicle, but the ruptured follicle stays on the surface of the ovary. For the next two weeks or so, the follicle transforms into a structure known as the CORPUS LUTEUM. This structure starts releasing progesterone, along with small amounts of estrogen. This combination of hormones maintains the thickened lining of the uterus, waiting for a fertilized egg to implant
Luteal Phase
A hormone that is detected in a urine test for pregnancy
Human Chorionic Gonadotrophin
keeps producing the raised levels of progesterone that are needed to maintain the thickened lining of the uterus
corpus luteum
explain luteal phase
During ovulation, the egg bursts from its follicle, but the ruptured follicle stays on the surface of the ovary. For the next two weeks or so, the follicle transforms into a structure known as the CORPUS LUTEUM. This structure starts releasing progesterone, along with small amounts of estrogen. This combination of hormones maintains the thickened lining of the uterus, waiting for a fertilized egg to implant
if the pregnancy does not occur, the corpus luteum withers and dies, usually around ____
day 22 in a 28-day cycle
What causes the lining of the uterus to fall away. This is known as menstruation. The cycle then repeats
Drop in progesterone levels
Days 1-5 cycle
Shedding of the endometrium occurs as uterine bleeding, approximately 50 to 60 ml (<2 ounces)
Menstrual phase
Day 5 of ovulation. Endometrium is restored under primary hormone influence of estrogen. In this preovulationary phase, FSH is secreted by the anterior pituitary. Preovulatory surge of LH affects one follicle and ovulation occurs
Proliferative (follicular) phase
(Ovulation) ovulation to approximately 3 days before menstrual cycle. Estrogen levels off and progesterone level increase
Secretory Phase
(Luteal) If fertilization did not occur, the corpus luteum degenerated and estrogen and progesterone levels drop off causing the endometrium to become “blood starved” leading to menstruation
Ischemic Phase
Two common causes of irregular menstrual periods are
-polycystic ovary syndrome (PCOS)
-Hypothyroidism
Is a hormone imbalance that can affect ovulation, and make it more difficult to get pregnant
PCOS
is a man or woman who is able and willing to give the proper response to the demands of a given situation with specific reference to marriage and family life
responsible person
is one who gives the proper responses to the needs of his/her spouse, as well as his own, and of their life together
responsible spouse
Give proper responses to the needs of their children
Responsible parents
Refers more specifically to the voluntary and positive action of a couple to plan and decide the number of children they want to have and when to have them
Family planning
