π©Ί FEMALE INFERTILITY β CAUSES, EVALUATION & TREATMENT
Looking to learn about female infertility for an exam or in practice? Here's a high-yield summary of the causes, investigation and management all in one place.
πΉ WHEN SHOULD INFERTILITY BE EVALUATED?
Under 35 years: after 12 months of regular unprotected in*******se.
35 years or older: after 6 months.
Earlier assessment may be appropriate when there are risk factors such as amenorrhea, suspected tubal disease, endometriosis, previous pelvic surgery or other known reproductive problems.
𧬠MAJOR CAUSES OF FEMALE INFERTILITY
1β£ Ovulatory dysfunction
β’ PCOS
β’ Hypothalamic dysfunction
β’ Hyperprolactinemia
β’ Thyroid disorders
β’ Primary ovarian insufficiency
2β£ Tubal & peritoneal factors
β’ Previous PID
β’ Ge***al tuberculosis
β’ Previous pelvic surgery
β’ Endometriosis
β’ Tubal occlusion
3β£ Uterine factors
β’ Submucosal fibroids
β’ Endometrial polyps
β’ Intrauterine adhesions
β’ Congenital uterine anomalies
4β£ Age & ovarian reserve
Advancing maternal age is associated with declining ovarian reserve and, importantly, declining oocyte quality.
5β£ Cervical factors
Usually uncommon as an isolated cause.
6β£ Unexplained infertility
No identifiable cause despite a standard infertility evaluation.
π§ͺ HOW IS FEMALE INFERTILITY EVALUATED?
Think:
OVULATION + TUBES + UTERUS + OVARIAN RESERVE + MALE PARTNER
π©Έ Ovulation
β’ Menstrual history
β’ Appropriately timed serum progesterone
β’ TSH/prolactin when clinically indicated
β’ Additional hormonal testing depending on the presentation
π₯ Ovarian reserve
β’ AMH
β’ Antral follicle count (AFC)
β’ FSH/estradiol in selected cases
β οΈ Important: ovarian-reserve tests help estimate ovarian response to stimulation but do not independently diagnose infertility.
π©» Tubal patency
β’ HSG is a commonly used test
β’ HyCoSy or laparoscopy with chromopertubation may be used in selected patients.
π« Uterus
β’ Transva**nal ultrasound
β’ Saline infusion sonography or hysteroscopy when indicated
π¨ββοΈ Male partner
The male partner should be evaluated at the same time, particularly with semen analysis.
π TREATMENT β DEPENDS ON THE CAUSE
πΉ Ovulatory dysfunction
Treat the underlying cause and use ovulation induction when appropriate.
In anovulatory infertility associated with PCOS, letrozole is generally recommended as first-line pharmacological ovulation induction when there are no other infertility factors.
πΉ Tubal disease
Selected patients may benefit from tubal surgery, while significant bilateral tubal damage may require IVF.
πΉ Endometriosis
Management is individualized according to age, severity, ovarian reserve, duration of infertility and other factors; surgery and/or assisted reproductive techniques may be considered.
πΉ Unexplained infertility
Depending on age and prognosis, ovarian stimulation with IUI may be used before proceeding to IVF in appropriate patients.
π― EXAM PEARLS
β Ovulatory dysfunction is a major cause of female infertility.
β PCOS is a common endocrine cause of anovulatory infertility.
β HSG is an important investigation for tubal patency.
β AMH is a marker of ovarian reserve β not a standalone infertility test.
β Always remember to assess the male partner simultaneously.
