Delayed Puberty
-Female → no breast development by age 13
-Increased risk for inadequate skeletal development/mineralization
-Psychosocial implications'
-Often due to physiologic (constitutional delay) → maturation is happening, just very slowly.
Hormone levels are normal, HPG axis intact.
Precocious puberty
-Puberty occurs too early
-3 types:
Central precocious → GnRH dependent
Peripheral precocious → GnRH independent
Benign Precocious → neither
-Results in premature closure of growth plates in long bones → lifelong short stature → profound psychosocial consequences.
Dysmenorrhea
Primary/Secondary amenorrhea
Abnormal Uterine bleeding (AUB)
Polycystic ovary syndrome (PCOS)

Premenstrual dysphoric disorder (PMDD)
What are the hormonal and menstrual alterations of the female reproductive system?
Dysmenorrhea
Painful menstruation, typically involving abdominal cramps.
Primary Dysmenorrhea
Recurrent, Painful menstruation, NO pelvic disease.
Excessive PG in ovulatory cycles → myometrial stimulant and vasoconstrictor.
Onset → a few days before menstruation and persists 48-72 hrs.
-Risk factors:
Women > 30
Have not given birth
Hx of sexual assault, PMS, or sterilization
Heavy tobacco/alcohol users
Family history
BMI < 20
Secondary Dysmenorrhea

Manifests later in reproductive years.
May occur anytime in the menstrual cycle
Associated with endometriosis, and all the other pelvic disorders.
Primary Amenorrhea
Failure of menarche and absence of menstruation by age 14 without secondary sex characteristics.
Or absence of menstruation by 16 years of age regardless of secondary sex characteristics.
-Common causes;
Anatomic defects
Elevated FSH → ovarian failure
Hyperprolactinemia → prolactin inhibits GnRH
Hypothalamic amenorrhea → lack of GNrH secretion
PCOS
Secondary Amenorrhea
Cessation of previous menses for more than 3 months (regular cycles) or 6 months (irregular cycles)
Common during early adolescence, pregnancy, lactation, and perimenopausal period.

Hyperandrogenic state: cardinal feature
-Diagnostic criteria:
Ovulatory dysfunction (menstrual irregularity)
Hyperandrogenism

causes scaring and other issues.
May involve any or all organs in the upper genital tract → uterus, fallopian tubes, or ovaries.
Typically an ascending infection → spread from lower genital tract.
-Salpingitis → inflammation of the fallopian tubes
-Oophoritis → inflammation of the ovaries.
-Most severe form affects the entire peritoneal cavity.
-Etiology: most often caused by STI
Chlamydia - Chlamydia trachomatis
Gonorrhea - Neisseria gonorrhoeae
Vaginitis
Irritation or inflammation of the vagina caused by infection, irritants, pathologies, disruption of normal flora.
Most common causes:
Overgrowth of normal flora → candida albicans
STIs → Trichomoniasis, HSV infection
Vaginal irritation due to low E2 during menopause → atrophic vaginitis.
-Pathophysiology: Alteration in vaginal environment
Local defense mechs. → skin integrity, immune reaction
Vaginal pH affected by → semen, douches, soaps, spermicides.
Antibiotics → destroys normal vaginal flora → overgrowth of C. albicans.
Cervicitis
Inflammation of the cervix.
purulent or mucopurulent discharge from the cervical os
AND/OR endocervical bleeding
-Infectious (most common) → younger, sexually active due to STI
Chlamydia (C. trachomatis), Neisseria (N. gonorrhoeae).
-non-infectious → older women
Typically irritation from abnormal vaginal flora due to low vaginal E2

Can protrude from vaginal opening
Cystocele: Descent of portion of the posterior bladder wall and trigone into the vaginal canal.
AKA anterior compartment prolapse
Usually caused by childbirth

Benign Ovarian Cysts
-Most common during the reproductive years
Typically unilateral; random or recurrent events.
5-6cm in diameter; can be up to 8-10cm
Usually asymptomatic
-Follicular cysts: Dominant follicle fails to rupture or 1+ dominant follicles regress
Fluid-filled, may be absorbed or regressed.
-Corpus luteum cysts: Formed from the granulosa cells left behind after ovulation.
Highly vascularized, hemorrhagic cysts
Less common, cause more symptoms.
Endometrial Polyps
-A benign mass of endometrial tissue that contains a variable number of glands, stroma, and blood vessels.
Usually solitary and structurally diverse
Seen at any age, often 40-50.
-Risk Factors: Old age, Obesity, nulliparity, early menarche or late menopause, estrogenic states, HTN, diabetes.
-Common cause of intermenstrual bleeding, excessive menstrual bleeding, suboptimal fertility.

-Commonly called myomas or uterine fibroids.
Slow-growing tumor of myometrial smooth muscle
Most common benign tumor of the uterus
Most are small and asymptomatic.
-Risk factors: black, age, FH, Nulliparitiy..
-Mutation in MED12 gene common
-Tumor growth → ischemia → necrosis/degeneration → vaginal bleeding.
Adenomyosis
-Prescence of endometrial tissue within the uterine myometrium
Tissue DOES NOT respond to cyclic hormone changes.
-Risk factors: Increased estrogen exposure, Prior uterine surgery.
-unknown mech.
Adenomyosis → increased PGs → dysmenorrhea
Adenomyosis → increased vascularization, abnormal uterine contractions → heavy menstrual bleeding.
Endometriosis
-The presence of functioning endometrial tissue outside of the uterus. (ectopic endometrium)
Most common location is on the ovaries
-Most common cause of chronic pelvic pain
3rd most common reason for hysterectomy
Higher risk for infertility and cancer
-Pathology:
Growth depends on E2! Endometrial remodeling is a cyclical process affected by the E2 blood supply and the presence of glandular and stromal cells.
Stage 1: 1-5 points, superficial lesions
Stage 2: 6-15 points, some deep lesions
Stage 3: 16-40 points, minor adhesions, endometrioma.
Stage 4: >40 points, severe adhesions w/ bowel and bladder involvement. severe damage to the pouch of Douglas.
Cervical cancer
-4th most common cancer
-Caused by HPV
HPV-16, HPV-18
-HPV infects cells and causes mutation with p53 gene → uncontrolled proliferation
Endometrial cancer
-6th most common cancer.
-Risk factor: prolonged exposure to unopposed E2.
This leads to constant stimulation of the endometrium.
P4-R inhibits this, when dysfunctional → endometrial hyperplasia.
Ovarian cancer
-7th most common cancer
-5 year survival rate < 45%
-Risk factors: positive FH of breast or ovarian cancer
-Pathophys.
Most cases → sporadic acquired somatic mutations (TP53 gene)
-Tumors arise from 3 ovarian components
Can be benign or malignant
(60%) Epithelial cells →cover the ovary
(30%) Germ cells → endoderm → oocytes
(8%) Sex cord/stromal cells → hormone-producing cells.
