Diagnostic laparoscopy helps in identifying the hidden aetiology
of infertility so that a therapeutic intervention can be initiated, by avoiding
unnecessary empiric medical treatment for ovulation induction. In some
patients, diagnostic laparoscopy alters treatment plans, including earlier
utilisation of assisted reproductive technology.
Ovarian pathology and tubal blockage are found to be the
most common cause of infertility followed by pelvic adhesions in infertile
patients undergoing laparoscopy. Cystic ovaries, endometriosis, chocolate cyst,
adhesion, or endometriotic implants are also seen.
Polycystic ovary syndrome (PCOS) is a more common disorder,
affecting approximately 5–10% of infertile women. Polycystic ovarian disease
causes hormonal imbalance in women that is thought to be one of the leading
causes of female infertility. It contributes to more than 75% of cases of anovulatory
infertility. The main goal of treatment is the induction of single mature egg
in a cycle. A judicious management of infertility in PCOS will allow most
patients to conceive. Weight loss and clomiphene citrate (CC) are the
first-line components of patient’s treatment before gonadotrophins are used.
However, during gonadotrophin administration, there is a high risk of ovarian
hyper-stimulation and multiple pregnancies. So, surgery with laparoscopic
ovarian drilling is often used before gonadotrophins in order to obtain normal
ovulatory cycles. Ovarian drilling have the advantage of improving the hormonal
milieu, inducing mono-follicular growth, avoiding the risk of ovarian hyper
stimulation syndrome and minimizing the rate of multiple pregnancy.
Generally, laparoscopy should be reserved for couples who have already completed a more basic infertility evaluation including assessing for ovulation, ovarian reserve, ultrasound and
hysterosalpingogram for the female and semen analysis for the male. Some couples may choose to skip laparoscopy and proceed to other fertility treatments such as superovulation with fertility
medications combined with intrauterine insemination or in vitro fertilization.
Operative procedures, such as adhesiolysis, ablation of endometriosis, tuboplasty and salpingectomy for hydrosalpinx or pyosalpinx at the time of laparoscopy can enhance
conception, naturally or with intra uterine insemination or in vitro fertilization.
