MENSTRUAL

CYCLE

Group 1

Menstrual Cycle

 Menstrual cycle is regulated by fluctuating levels of sex hormones

 These hormones produce certain changes in the ovaries and uterus

 Humans are nearly unique among species in having a menstrual cycle

 Other species of mammals have estrous cycles

Basic terms

 Endometrium: Lining of the uterus

 Oocyte: Developing reproductive cell

 Ovum: Mature egg after meiosis

 Menopause: Last menstrual cycle, afterwhich egg production stops

4 phases of menstrual cycle

Menstrual flow

Proliferative

Ovulation

Luteal

• Menstruation

• This is the first, but also in some ways the last, phase of your menstrual cycle. It’s when the thickened lining of your uterus sheds during your monthly period. Menstruation can last from three to seven days, depending on the length of your cycle.

• Follicular phase

• This starts on the first day of your menstrual period and ends when you start to ovulate.

During this phase, the egg-containing pods called follicles ripen and one of the eggs matures.

• Ovulation

• This phase happens when the ovary releases that mature egg down the fallopian tube on its way to fertilization. This is the shortest phase of the cycle , lasting just 24 hours.

• Luteal phase

• In this phase, the follicle that released the egg produces hormones that thicken and ripen the uterus to ready it for pregnancy.

During which days of the cycle is FSH at its lowest?

 FSH: follicle stimulating hormones is at its lowest during the last days of the cycle

When FSH levels are low what is the size of the follicle

• It is shrinking and disappearing while a new set is growing.

What is happening to estrogen during the follicle phase?

- It dips then rises

- In response the uterus lining dips then rises

Ovulation

 Day 14 of the cycle usually marks an event called ovulation

 Follicle ruptures open and releases the ripened egg

 Pituitary hormones: LH and

FSH are peaking

 Estrogen is also released from follicle

Hormones and What Happens in the Ovaries

• Luteal phase - after releasing an egg, the follicle turns into the corpus luteum

– The corpus luteum manufactures progesterone

• Menstruation - shedding of the inner lining of the uterus

Length and Timing of the Cycle

Normal menstrual cycle = 20 to 36 to 40 days; average is about 28 days

– Menstruation begins on day 1 and continues until about day 4 or 5

– Follicular phase extends from about day 5 to about day

13

– Ovulation occurs on day 14

– Luteal phase extends from day 15 to the end of the cycle, day 28

Other Cyclic Changes

Two other physiological processes fluctuate with the menstrual cycle:

– The cervical mucus cycle

– The basal body temperature cycle

Fluctuations in Performance

• Research on intellectual or athletic performance generally shows no fluctuations over the cycle

• Research on academic performance, problem solving, memory, or creative thinking shows no fluctuations over the cycle

What Causes the Fluctuations in

Mood

Biological factors

– Fluctuations in levels of hormones

• Environmental factors

– Menstrual taboos and cultural expectations

MENSTRUAL DISORDERS,

SYMPTOMS, CAUSES &

CURE

Abnormal Uterine

Bleeding

Symptoms:

 Menorrhagia

(heavy menstrual bleeding)

 Bleeding at unusual times

(between periods, after sex, during menopause)

 Unusually long periods

(seven days or longer)

 Inconsistent menstrual cycles

Abnormal Uterine Bleeding

(AUB)

Cure/Treatment

Causes

• Medication

• Structural abnormalities in the uterus, including:

• Birth control pills or hormonereleasing intrauterine devices.

• Fibroids (non-cancerous growths of muscle in the uterus)

• Polyps (non-cancerous growths on the lining of the uterus and cervix)

• Uterine fibroid embolization (UFE) . In this minimally invasive procedure guided by an x-ray camera called a fluoroscope, tiny particles are injected through a catheter into uterine arteries that are delivering blood to fibroids, blocking blood flow and causing the fibroids to shrink.

• Uterine cancer

• Cervical cancer

• Blood thinners for anticoagulation

(medications that reduce the risk of blood clots)

• Endometrial ablation . Guided by a narrow lighted tube with a viewing device on the end (called a hysteroscope), the lining of the uterus is destroyed using a laser or other specialized instruments that produce heat, freezing, microwave energy or electrical currents.

• Myomectomy , the surgical removal of fibroids.

• Platelet dysfunction

• Dilation and curettage (D&C) . A procedure in which endometrial tissue is gently scraped or suctioned from the uterus.

• Early pregnancy

• Hormonal changes

• Hysterectomy . A surgical procedure in which the uterus is removed.

Symptoms:

Dysmenorrhea

/Menstrual

Cramps

 Aching pain in the abdomen (pain may be severe at times)

 Feeling of pressure in the abdomen

 Pain in the hips, lower back, and inner thighs

Dysmenorrhea

Causes:

• Menstrual cramps are caused by contractions

(tightening) in the uterus (which is a muscle) by a chemical called prostaglandin. The uterus, where a baby grows, contracts throughout a woman's menstrual cycle.

During menstruation, the uterus contracts more strongly. If the uterus contracts too strongly, it can press against nearby blood vessels, cutting off the supply of oxygen to the muscle tissue of the uterus. Pain results when part of the muscle briefly loses its supply of oxygen.

Cure:

• For best relief, you should take ibuprofen as soon as bleeding or cramping starts. You may take aspirin or another pain reliever such as acetaminophen.

• Place a heating pad or hot water bottle on your lower back or abdomen.

• Rest when needed.

• Avoid foods that contain caffeine .

• Avoid smoking and drinking alcohol .

• Massage your lower back and abdomen.

Premenstrual

Syndrome (PMS)

Symptoms:

 Mood swings

 Marked anger

 Irritability

 Tension

 Decreased interest in usual activities

 Fatigue

 Change in appetite

 Sleep problems

 Physical problems, such as bloating

Premenstrual Syndrome (PMS)

Causes:

• The exact cause of PMS is unknown, but it seems to be related to the fluctuating levels of hormones (including estrogen and progesterone) that occur in preparation for menstruation.

Cure:

• Over-the-counter pain relievers.

• Balanced Diet & Exercise

2 Types of

Amenorrhea

• Primary

• Secondary

Symptoms:

The main sign of amenorrhea is the absence of menstrual periods. Depending on the cause of amenorrhea, you might experience other signs or symptoms along with the absence of periods, such as:

• Milky nipple discharge

• Hair loss

• Headache

• Vision changes

• Excess facial hair

• Pelvic pain

• Acne

Primary:

Amenorrhea (Causes)

Secondary:

• Failure of the ovaries

(female sex organs that hold eggs).

• Problems with hormones secreted by the hypothalamus or the pituitary gland (areas in the brain that make hormones involved in menstruation.

• Poorly formed reproductive organs.

• Pregnancy.

• Breast feeding.

• No longer taking birth control pills.

• Menopause.

• Some birth control methods, such as Depo Provera.

Cure:

• Birth control pills or other types of hormonal medication.

Certain oral contraceptives may help restart the menstrual cycle.

• Medications to help relieve the symptoms of PCOS. ...

• Estrogen replacement therapy (ERT).

Menorrhagia

Symptoms:

• Soaking through one or more sanitary pads or tampons every hour for several consecutive hours

• Needing to use double sanitary protection to control your menstrual flow

• Needing to wake up to change sanitary protection during the night

• Bleeding for longer than a week

• Passing blood clots larger than a quarter

• Restricting daily activities due to heavy menstrual flow

• Symptoms of anemia, such as tiredness, fatigue or shortness of breath

Menorrhagia

Causes:

• Endometrial cancer

• Inflammation or infection of the vagina, cervix, or pelvic organs

• Polyps (small growths on the cervical or uterine wall)

• Thyroid conditions

• Liver, kidney, or blood disease, and the use of blood-thinning drugs

Cure:

• Bed rest may be recommended if bleeding is heavy.

• Record the number of pads or tampons you have used so that your doctor can determine the amount of bleeding.

Change tampons regularly, at least twice a day.

• See your gynecologist if symptoms persist.

DISEASES IN

REPRODUCTIVE

SYSTEM

Endometriosis

• Endometriosis is a problem affecting a woman’s uterus—the place where a baby grows when a woman is pregnant. Endometriosis is when the kind of tissue that normally lines the uterus grows somewhere else. It can grow on the ovaries, behind the uterus, on the bowels, or on the bladder.

Rarely, it grows in other parts of the body.

Symptoms:

 Severe menstrual cramps, unrelieved with NSAIDS

( Nonsteroidal antiinflammatory drugs)

 Long-term lower-back and pelvic pain

 Periods lasting longer than 7 days

 Heavy menstrual bleeding where the pad or tampon needs changing every 1 to 2 hours

 Bowel and urinary problems including pain, diarrhea , constipation , and bloating

 Bloody stool or urine

 Nausea and vomiting

 Fatigue

 Pain during intercourse

 Spotting or bleeding between periods

Causes:

1. Problems with menstrual flow

2. Embryonic cell growth

3. Fetal development

4. Surgical scar

5. Endometrial cell transport

6. Genetics

7. Hormones

8. Immune system

Cures:

 Surgery

 Pain medications

 Hormonal Therapies

 Fertility Treatment

Uterine Fibroids

• Uterine fibroids are the most common noncancerous tumors in women of childbearing age. Fibroids are made of muscle cells and other tissues that grow in and around the wall of the uterus, or womb. The cause of fibroids is unknown.

Risk factors include being African-

American or being overweight.

Symptoms:

 Heavy or painful periods or bleeding between periods.

 Feeling “full” in the lower abdomen.

 Urinating often.

 Pain during sex.

 Lower back pain.

 Reproductive problems, such as infertility, multiple miscarriages, or early labor.

Causes:

1. Genetic changes

2. Hormones

3. Other growth factors

4. Extracellular matrix (ECM is a threedimensional network of extracellular macromol ecules , such as collagen , enzymes , and glycoproteins , that provide structural and biochemical support of surrounding cells. Because multicellul arity evolved)

Cures:

 Gonadotropin-releasing hormone (GnRH) agonists

 Progestin-releasing intrauterine device (IUD – a device inserted to the uterus to prevent pregnancy )

 Tranexamic acid (Lysteda,

Cyklokapron)

 Other medications

Gynecologic

Cancer

• Gynecologic cancer is any cancer that starts in a woman's reproductive organs. Five main types of cancer affect a woman's reproductive organs are cervical, ovarian, uterine, vaginal and vulvar. As a group, they are referred to as gynecologic cancer. A sixth type of gynecologic cancer is the very rare fallopian tube cancer.

Symptoms

Causes:

 Reproductive and menstrual history including never having children, starting your menstruation before age 12 and/or going through menopause after age 55

 Diabetes

 Human papillomavirus (HPV) infection

 Smoking

 HIV infection or a weak immune system

 Obesity

 Previous history of breast or gynecologic cancer

 Older age

 Family history

 Use of oral birth control and/or fertility drugs

 Estrogen therapy

 High-fat diet

 Prior radiation to pelvic area

Cures:

 Surgeries

 Chemotherapies

 Radiations

HIV/AIDS

There are 3 stages: stage 1: acute stage , the first few weeks after transmission

stage 2: clinical latency, or chronic stage

stage 3: AIDS

• HIV is the human immunodeficiency virus.

HIV affects specific cells of the immune system (called CD4 cells). Over time, HIV can destroy so many of these cells that the body can’t fight off infection anymore. The human body cannot get rid of HIV—that means once a person has HIV, he or she has it for life. There is no cure at this time, but with proper medical care, the virus can be controlled. HIV is the virus that can lead to acquired immune deficiency syndrome, or

AIDS. AIDS is the late stage of HIV infection, when a person’s immune system is severely damaged.

Causes:

 Infected Blood

 Sharing drug needles

 Unprotected Sex (semen, vaginal fluids)

 Breast milk

 Sharing tattoo equipments

 Oral sex

 Contact between open wounds/ skin

 Etc.

Cure:

 There is no cure for HIV, although antiretroviral treatment can control the virus, meaning that people with HIV can live long and healthy lives.

 Most research is looking for a functional

cure where HIV is reduced to undetectable and harmless levels in the body permanently, but some residual virus may remain.

 Other research is looking for a sterilising

cure where HIV is eradicated from the body completely, but this is more complex and risky.

 Trials of HIV vaccines are encouraging, but so far offer partial protection only.

Interstitial Cystitis

• Interstitial cystitis (IC) is a chronic bladder condition resulting in recurring discomfort or pain in the bladder or surrounding pelvic region. People with IC usually have inflamed or irritated bladder walls that can cause scarring and stiffening of the bladder. IC can affect anyone; however, it is more common in women than men.

Symptoms:

 Abdominal or pelvic mild discomfort.

 Frequent urination.

 A feeling of urgency to urinate.

 Feeling of abdominal or pelvic pressure.

 Tenderness.

 Intense pain in the bladder or pelvic region.

 Severe lower abdominal pain that intensifies as the urinary bladder fills or empties.

Causes:

 Defects in the lining of the urinary bladder that cause irritation.

 Bladder trauma or overstretching.

 Pelvic floor muscle dysfunction.

 Autoimmune disorders.

 Primary neurogenic inflammation.

 Spinal cord trauma.

 Genetics.

 Allergy.

Cures:

 Lifestyle changes

 Bladder training

 Physical therapy

 Medicines

 Bladder procedures

Polycystic Ovary Syndrome (PCOS)

• Polycystic ovary syndrome happens when a woman’s ovaries or adrenal glands produce more male hormones than normal. One result is that cysts (fluid-filled sacs) develop on the ovaries. Women who are obese are more likely to have

PCOS. Women with PCOS are at increased risk of developing diabetes and heart disease.

Symptoms: Causes:

• Infertility.

• Pelvic pain.

• Excess hair growth on the face, chest, stomach, thumbs, or toes.

• Baldness or thinning hair.

• Acne, oily skin, or dandruff.

• Patches of thickened dark brown or black skin.

• Genes

• Insulin resistance

• Inflammation

Cure:

• Lifestyle change

• Combination birth control pills

• Progestin therapy

• Etc.

Sexually Transmitted Diseases (STDs)

• STDs are infections that you can get from having sex with someone who has the infection. The causes of STDs are bacteria, parasites, and viruses. There are more than

20 types of STDs.

• Most STDs affect both men and women, but in many cases the health problems they cause can be more severe for women. If a pregnant woman has an STD, it can cause serious health problems for the baby.

Symptoms: Causes:

 Sores or bumps on the genitals or in the oral or rectal area

 Painful or burning urination

 Discharge from the penis

 Unusual or odd-smelling vaginal discharge

 Unusual vaginal bleeding

 Pain during sex

 Sore, swollen lymph nodes, particularly in the groin but sometimes more widespread

 Lower abdominal pain

 Fever

 Rash over the trunk, hands or feet

The germs that cause STDs hide in semen, blood , vaginal secretions, and sometimes saliva . Most of the organisms are spread by vaginal, anal, or oral sex, but some, such as those that cause genital herpes and genital warts, may be spread through skin contact. You can get hepatitis B by sharing personal items, such as toothbrushes or razors, with someone who has it.

Cure:

 Abstain

 Stay with one uninfected partner

 Wait & test

 Get vaccinated

 Use condoms and other protective items.

 Don't drink alcohol excessively or use drugs

 Communicate

 Consider male circumcision

 Etc.

Keeping the Reproductive System

Healthy

• Eat a balanced diet that is high in fiber and low in fat.

• Drink plenty of water.

• Get regular exercise.

• Maintain a healthy weight.

• Get enough sleep.

• Avoid using tobacco, alcohol, or other drugs.

• Manage stress in healthy ways.

• Use condoms or any other object that can and will protect you from being pregnant and having STDs
