Abstract
Introduction: Physiologic & functional Ovarian Cysts are most commonly seen in reproductive age group
but also to be seen in any age group from infancy to postmenopausal period. Incidence of Ovarian Cyst in
gynaec OPD at attending OPD in Dr.V.R.K Hospital is 0.6%. The study was conducted to evaluate the
percentage of regression of ovarian cyst with 3 months OCPs (Category II 3 menstrual cycles — either
underwent ultrasound follow-up for 3 months or administration of OCP (oral combined pills for 3 months).
Methodology: A prospective study was conducted in which women presenting with complaints such as
abdominal pain, bloating, menstrual irregularities, or those found to be asymptomatic but diagnosed wit h
ovarian cysts were evaluated. Diagnosis was established using pelvic ultrasonography (USG) and serum
CA-125 levels. Women with ovarian cysts identified on USG were further assessed with CA -125 to
exclude pathological conditions. Patients diagnosed with f unctional ovarian cysts were administered oral
contraceptive pills (OCPs) for a period of three months, after which follow -up pelvic USG was performed
to assess regression.
Results
Out of about 32 women studied for 3 months: CA125 levels were normal in fu nctional cysts.
Ovarian cyst in all 32 cases were of functional type. CA125 levels were raised in Endometriotic cysts. The
abnormal cases were ruled out. Regression of functional ovarian cysts was seen with OCP administration.

visually.
Conclusion
Combined oral contraceptives significantly promote regression of functional ovarian cysts by
suppressing ovulation. CA -125 evaluation is essential to differentia te benign from malignant or complex
cysts. Conservative management with OCPs remains an effective first -line option in reproductive -age
women.

Introduction
Among the most common gynecological disorders seen in women of all ages, from childhood to
postmenopause, ovarian cysts rank high. They can be physiological, functional, or pathological,
and the y depict sacs filled with fluid either inside or outside the ovary. Cysts in women of
childbearing age often develop normally during the ovulatory cycle and serve a useful purpose [1,
2].
Follicle cysts and corpus luteal cysts are the two main types of fu nctional ovarian cysts. If the
follicle doesn't burst or the sac doesn't disintegrate after ovulation, a follicular cyst will form.
Common characteristics of these cysts include thin walls, lack of eyes, and a diameter of 3 -5 cm.
Corpus luteal cysts, on th e other hand, are often bigger, have thicker walls, and can often be
associated with bleeding. While the majority of functional cysts do not cause any symptoms and
disappear on their own, a small percentage of women may have dysmenorrhea, bloating,
abdominal pain, or irregular periods. Women who visited the gynecology outpatient department
(OPD) at Dr. V.R.K. Hospital had a 0.6% incidence of ovarian cysts [3-5].
Although most cysts are harmless, it is important to distinguish them from endometriotic,
hemorrhagic, or malignant cysts. To this day, ultrasonography and serum CA -125 estimate are
the diagnostic evaluation's lynchpins, helping to differentiate between functional and abnormal
cysts. Medications or close observation are typically the first lines of d efense against functioning
ovarian cysts [6-8]. Because they reduce gonadotropin secretion, which in turn suppresses
ovulation, combined oral contraceptive pills (OCPs) are quite popular because they help existing
cysts to recede and prevent new cysts from forming. Despite mixed results from earlier research,
the use of OCPs to resolve cysts remains a topic of active clinical interest [9-11].

This study aimed to examine the correlation between clinical
presentation, sonographic findings, and CA -125 level s in order
to assess the regression of functional ovarian cysts after OCP
treatment in reproductive-aged women.
Materials and methods
A prospective, randomized study was conducted in the
Department of Gynecology, Dr. V.R.K. Hospital, from January
2023 to December 2023. The study population included women
presenting to the gynecology outpatient department (OPD) with
symptoms suggestive of ovarian cysts or those diagnosed
incidentally on ultrasonography (USG). A total of 6,527 women
attended the gynecology OPD during the study period. Out of
these, 110 patients were diagnosed with ovarian cysts based on
pelvic USG.
Inclusion Criteria
Women of reproductive age (adolescent to premenopausal).
Functional ovarian cysts measuring <7 cm in diameter.
Cysts with thin walls, unilocular structure, and clear fluid
content.
Serum CA-125 levels 7 cm).
Postmenopausal ovarian cysts.
Suspected malignant ovarian masses.
Diagnostic Evaluation
All patients underwent pelvic USG to assess cyst size, wall
thickness, septations, and internal echoes. Measured in all
patients to differentiate functional cysts from endometriotic or
neoplastic cysts. Patients with elevated CA -125 (>300 I U/ml)
were excluded from the functional cyst group.
Intervention
Patients with functional ovarian cysts (n = 96) were divided into
two groups:
1. OCP group (n = 48): Received combined oral contraceptive
pills for three consecutive menstrual cycles.
2. Control group (n = 48): Kept under conservative
observation without medical therapy.
Follow-up USG was performed after three months to evaluate
cyst regression.
Outcome Measures
Regression or persistence of ovarian cysts on follow -up
USG.
Correlation of CA-125 levels with different types of ovarian
cysts.
Age-wise distribution of ovarian cysts.
Results
During the study period (January -December 2023), 110 patients
were assessed for ovarian cysts. Outpatient gynecology patients
had a 0.6% overall incidence of ova rian cysts. Although fewer
occurrences were found in adolescents and postmenopausal
women, the reproductive age group (21 -40 years) accounted for
the bulk of ovarian cyst diagnoses.
Age Distribution
The age group of 31 -40 years old women had the highest
frequency of ovarian cysts, followed by the 21 -30 year old
women. In women under the age of 20 and above the age of 50,
only a small number of cases were identified.

Ovarian cysts are more prevalent in women of childbearing age,
as the age group between 31 and 40 years old had the highest
number of cases (45 patients).
Distribution of Ovarian Cysts by Age
Women between the ages of 21 and 30 had the greatest
frequency of ovarian cysts (54 cases), followed by those
between the ages of 31 and 40 (51 cases). Women who had gone
through menopause had the lowest incidence.

Ovarian cysts are most common in women between the ages of
21 and 40, which is close to the reproduct ive age, according to
the study's authors.
Monthly Distribution of Cases
The majority of cases concentrated in the 21 -40 year old age
category, as also shown in the monthly analysis.

The age range of 31 -40 years old continued to have the highest
number of reported cases, demonstrating that this is the
demographic most impacted by the disease.

Additionally, the pattern that was present in June showed that
the 21 -40-year age group had the gr eatest number of cases,
while women who were above the age of 50 had very few
occurrences.
Correlation with CA-125 Levels
CA-125 estimation was performed for all patients to differentiate
functional from pathological cysts. The findings were as
follows:
Fig 1: Distribution of ovarian cysts among study participants
Functional ovarian cysts: Normal or slightly reduced CA -
125 levels.
Adolescent age group: Predominantly normal CA-125.
Perimenopausal age group: Normal to mildly raised CA -
125.
Endometriotic cysts: Significantly raised CA-125.
Hemorrhagic cysts: Mild elevation of CA-125.
Malignant cysts: Markedly elevated CA-125 (>300 IU/ml).
Functional cysts were consistently associated with normal CA -
125 levels, while raised CA-125 was indicative of endometriotic,
hemorrhagic, or malignant cysts.
Discussion
Gynecological conditions including ovarian cysts are common in
reproductive-age women. The gynecology OPD had 0.6%
ovarian cysts, which is similar to other hospital -based research.
Most of the 110 c ases (87%) were functioning ovarian cysts,
while complicated, torsion, and postmenopausal cysts were rare.
One case of ovarian cystadenocarcinoma was also found,
reinforcing the significance of rigorous evaluation and
discrimination between benign and mali gnant ovarian tumors [12-
14].
Functional ovarian cysts result from follicular rupture failure or
corpus luteum persistence following ovulation. Though thin -
walled, unilocular, and self -limiting, these cysts can cause pain,
bloating, and menstrual abnormal ities. Our study found that
functional cysts were more common in women aged 21 -40,
when ovulatory activity is highest. The lower number of
instances in teens and postmenopausal women supports the
hormonal theory of functional cysts [15-17].
In this trial, 48 women with functioning ovarian cysts got
combination OCPs for three menstrual cycles and 48 were
conservatively handled. OCP patients had higher cyst regression.
This supports the well -established mechanism of OCPs, which
restrict ovulation by blocking GnRH secretion and lowering
FSH and LH. The absence of the LH surge precludes ovulation
and subsequent cyst production, therefore aiding regression of
existing functional cysts. In our study, the 21 -30-year age group
had the most cysts, which correlates w ith peak reproductive
activity. Unmarried women (30%) also had ovarian cysts,
demonstrating that marital status does not protect against them.
Women with parity 3 had the highest incidence (35%). Parity
did not directly affect functional ovarian cysts [18-20].
The serum CA -125 test helped identify functional cysts from
unhealthy ones. Our investigation found normal CA -125 levels
in functioning ovarian cysts but increased levels in 8 individuals.
Cystadenocarcinoma (3 instances) had markedly elevated CA -
125 values, while endometriotic and hemorrhagic cysts had
modest elevations. This suggests that CA -125 should be
included in ovarian cyst diagnostics to rule out malignancy and
other complex disorders [21-23].
Most reproductive -age ovarian cysts are function al and
disappear naturally or with OCP, according to previous studies.
These data support OCPs as an effective and conservative
treatment method, as do our results. We found that complicated
cysts, endometriotic cysts, and malignancies can appear as

functional cysts on imaging, highlighting the necessity for USG
and CA-125 screening [24-26].
Conclusion
This study shows that ovarian cysts, both functional and
physiological, can be regressed after three menstrual cycles of
taking combined oral contraceptiv e pills. The effectiveness of
OCPs as a non -invasive, conservative treatment choice was
demonstrated by the large number of patients who had full or
partial remission. Suppressing the hypothalamic -pituitary-
ovarian (HPO) axis, which stops ovulation and low ers the
chance of cyst development and persistence, is the mechanism
by which it helps. In addition, the study highlights the
significance of serum CA -125 estimation in distinguishing
benign functional cysts from pathological or cancerous versions,
which s hould be done in all women who report with ovarian
cysts. Better patient outcomes and fewer needless surgical
procedures are possible results of early detection and proper
care. As long as the possibility of malignancy is ruled out
through proper diagnostic examination, functional ovarian cysts,
which are prevalent in reproductive -age women, can be
conservatively treated with OCPs.
