Introduction to Reproductive Systems

The reproductive systems are essential for the continuation of life, responsible for producing offspring. They also play a crucial role in hormone production, influencing many other bodily functions. This guide explores the structures and functions of the male and female reproductive systems, common menstrual cycle disorders, and pelvic inflammatory disease (PID).

Male System

Focuses on sperm and hormone production and delivery.

Female System

Focuses on egg production, fertilization, pregnancy, and birth.

Male Reproductive System

Testes

Oval-shaped organs located in the scrotum. Primary function: produce sperm (spermatogenesis) and male hormones (androgens, mainly testosterone).

Epididymis

A coiled tube located on the back of the testis. Function: where sperm mature and are stored before ejaculation.

Vas Deferens

A tube that carries sperm from the epididymis to the ejaculatory duct. Function: rapid transport of sperm during ejaculation.

Accessory Glands: Prostate Gland, Seminal Vesicles, Bulbourethral Glands

These glands produce fluids that mix with sperm to form semen. Seminal vesicles contribute fructose (energy for sperm) and clotting factors. The prostate gland contributes a milky fluid that helps sperm motility. Bulbourethral (Cowper's) glands produce a pre-ejaculatory fluid that lubricates the urethra and neutralizes acidity.

Urethra

The tube that carries urine from the bladder out of the body. In males, it also carries semen during ejaculation. It extends from the bladder through the prostate gland and the penis.

Female Reproductive System

Ovaries

Two almond-sized organs located in the pelvic cavity. Primary function: produce eggs (ova) and female hormones (estrogen and progesterone).

Fallopian Tubes (Uterine Tubes)

Tubes that extend from the uterus towards the ovaries. Function: transport the egg from the ovary to the uterus. Fertilization typically occurs in the fallopian tubes.

Uterus

A hollow, pear-shaped muscular organ located in the pelvic cavity. Function: receives a fertilized egg and supports the development of a fetus during pregnancy. Has layers like the endometrium (inner lining, sheds during menstruation).

Cervix

The lower, narrow part of the uterus that opens into the vagina. Function: acts as a gateway, allowing menstrual blood to exit and sperm to enter the uterus. During pregnancy, it remains closed to protect the fetus and dilates during labor for birth. It also produces mucus that changes consistency throughout the menstrual cycle.

Menstrual Cycle Disorders

Various conditions can affect the regular menstrual cycle.

Amenorrhea

Description: Absence of menstruation.

Primary Amenorrhea: Menstruation has not started by age 15 or 16, even with normal secondary sexual development, or by age 13 without secondary sexual development.

Causes (Primary): Genetic or chromosomal abnormalities (e.g., Turner syndrome), structural problems with reproductive organs (e.g., absent uterus or vagina), hormonal imbalances (pituitary or hypothalamic problems), extreme exercise or weight loss.

Secondary Amenorrhea: Menstruation stops for 3 or more consecutive cycles (or 6 months) after cycles were previously established.

Causes (Secondary): Pregnancy (most common), breastfeeding, menopause, stress, significant weight loss or gain, excessive exercise, hormonal imbalances (PCOS, thyroid problems, pituitary tumors), certain medications.

Oligomenorrhea

Description: Infrequent menstruation, cycles longer than 35 days but less than 6 months apart.

Causes: Hormonal imbalances (common in adolescence or perimenopause), excessive exercise, stress, weight changes, certain medical conditions (e.g., PCOS, thyroid disorders).

Hypomenorrhea

Description: Very light menstrual bleeding.

Causes: Hormonal birth control pills, structural issues (e.g., Asherman's syndrome - scarring of the uterus), excessive exercise, stress, weight changes, hormonal imbalances.

Menorrhagia

Description: Abnormally heavy or prolonged menstrual bleeding.

Causes: Hormonal imbalances, uterine fibroids (non-cancerous growths), polyps, adenomyosis (uterine lining tissue grows into muscle wall), IUDs (especially non-hormonal), bleeding disorders, certain medications, uterine or cervical cancer (less common).

Metrorrhagia

Description: Irregular bleeding between periods.

Causes: Hormonal fluctuations (especially around ovulation or perimenopause), hormonal birth control, uterine fibroids or polyps, infections (cervical or uterine), pregnancy complications (e.g., ectopic pregnancy), cervical erosion, certain medical conditions, cancer (less common).

Dysmenorrhea

Description: Painful menstruation (menstrual cramps).

Primary Dysmenorrhea: Common menstrual cramps caused by prostaglandins (chemicals in the uterus that cause muscle contractions). Not due to an underlying condition.

Secondary Dysmenorrhea: Painful periods caused by an underlying medical condition affecting the reproductive organs.

Causes (Secondary): Endometriosis (tissue similar to uterine lining grows outside the uterus), uterine fibroids, adenomyosis, PID, ovarian cysts, cervical stenosis.

Premenstrual Syndrome (PMS)

Description: A group of physical, emotional, and behavioral symptoms that occur in the week or two before menstruation and usually resolve shortly after the period starts.

Symptoms: Mood swings, irritability, anxiety, depression, fatigue, bloating, breast tenderness, headaches, food cravings, trouble concentrating.

Premenstrual Dysphoric Disorder (PMDD)

Description: A more severe and debilitating form of PMS, characterized by significant mood disturbances.

Symptoms: Severe depression, anxiety, irritability, panic attacks, intense mood swings, persistent sadness or hopelessness, lack of interest in activities, fatigue, physical symptoms similar to PMS.

Polycystic Ovary Syndrome (PCOS)

Description: A complex hormonal disorder common among women of reproductive age. Characterized by hormonal imbalance (often high androgens), irregular or absent periods, and often small cysts on the ovaries (though cysts are not always present).

Symptoms: Irregular or absent periods, excess facial/body hair (hirsutism), acne, weight gain or difficulty losing weight, thinning scalp hair, difficulty getting pregnant.

Diagnosis and Treatment of Menstrual Disorders

Diagnosis involves understanding the pattern and severity of symptoms and identifying underlying causes.

Medical History and Physical Examination: Detailed questions about symptoms, menstrual history, sexual activity, and a pelvic exam.
Hormone Testing: Blood tests to check levels of various hormones (estrogen, progesterone, FSH, LH, androgens, thyroid hormones, prolactin).
Imaging Studies: Ultrasound (pelvic or transvaginal) to visualize reproductive organs and check for fibroids, cysts, polyps, or structural issues. MRI or CT may be used in specific cases.
Endometrial Biopsy: A small sample of the uterine lining is taken to examine under a microscope, especially in cases of abnormal bleeding to check for hyperplasia or cancer.
Treatment: Varies greatly depending on the specific disorder and its cause. Options include:
- Medications: Pain relievers (NSAIDs), hormonal birth control (pills, patches, rings, IUDs) to regulate cycles and reduce bleeding/pain, GnRH agonists, anti-fibrinolytics, progestins.
- Lifestyle Modifications: Diet, exercise, stress management.
- Surgery: For structural issues like fibroids, polyps, or severe endometriosis.
- Treatment of underlying conditions (e.g., thyroid medication for thyroid disorders, specific treatments for PCOS).

Pelvic Inflammatory Disease (PID)

An infection of the female reproductive organs, often caused by sexually transmitted bacteria.

Symptoms

Can be mild or severe. Some women have no symptoms. Common symptoms include:

Pelvic Pain: Often dull ache in the lower abdomen, can be constant or intermittent.
Abnormal Vaginal Discharge: Increased discharge, often with a foul odor.
Painful Urination: Burning sensation or difficulty urinating.
Irregular Menstrual Bleeding: Bleeding between periods or after sex.
Pain during sex, fever, chills, nausea, vomiting.

Causes

Usually caused by bacterial infection that travels up from the vagina or cervix into the uterus, fallopian tubes, or ovaries. The most common cause is sexually transmitted infections (STIs), particularly Chlamydia and Gonorrhea. Other bacteria can also cause PID.

Diagnosis and Treatment

Medical History and Physical Examination: Detailed history of symptoms, sexual activity, and a pelvic exam to check for tenderness and discharge.
Laboratory Tests: Swabs from the cervix/vagina to test for Gonorrhea, Chlamydia, and other bacteria. Blood tests may check for signs of infection or inflammation.
Ultrasound: Pelvic ultrasound to visualize reproductive organs and check for abscesses.
Treatment: Prompt treatment is essential to prevent long-term complications like infertility or chronic pain.
- Antibiotics: The primary treatment. Often a combination of antibiotics is given to cover various types of bacteria. It is crucial to complete the entire course of antibiotics.
- Treatment of Partner(s): Sexual partner(s) must also be tested and treated to prevent reinfection.
- Hospitalization: May be required for severe cases, pregnant women, those who don't respond to oral antibiotics, or if an abscess is suspected.
- Pain Management: Over-the-counter or prescription pain relievers.
- Avoidance of sexual intercourse during treatment.
