Introduction

Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women of reproductive age, with a prevalence of up to 10%. Various diagnostic criteria have been proposed, generally centered on the features of hyperandrogenism and/or hyperandrogenemia, oligo-ovulation and polycystic ovarian morphology [1]. Despite being heterogeneous in nature, the hallmarks of the disease are hyperandrogenism and chronic anovulation. Since it’s description in 1935 by Stein and Leventha [2,3]. Much has been learned about the pathophysiology of PCOS from its neuroendocrine underpinnings to an ever-growing understanding of the link between obesity, Insulin Resistance (IR) and PCOS [4]. Chronic anovulation often presents as oligomenorrhea, amenorrhea, dysfunctional uterine bleeding, and/or infertility. Interestingly, however, around 20% of patients with PCOS may describe normal menstrual cycle [5]. When clinically evaluating a patient for the possibility of PCOS, it is also important to search for signs of IR. Upper-body obesity is a key component of the IR syndrome [6]. However, obesity is not required for the diagnosis of PCOS with perhaps only 35% to 50% of these patients being obese [7-10].

The number of follicles and ovary volume are both important in the ultrasound evaluation. The criteria for PCOS put forth by Adams et al. are the most often cited: the presence of ≥ 10 cysts measuring 2-8 mm around a dense core of stroma or scattered within an increased amount of stroma [11]. A recent proposal to modify these criteria has been put forth by Jonard et al., [12] “increased ovarian area (>5.5 cm2) or volume (>11 mL) and/or presence of ≥ 12 follicles measuring 2 to 9 mm in diameter (mean of both ovaries)” [13]. These criteria had a specificity of 99% and a sensitivity of 75% for the diagnosis of PCOS. If the ovarian morphology is normal, then biochemical testing is undertaken. If any one or more of the following are noted, the diagnosis is confirmed: elevated LH, fasting glucose/insulin <4.5, and/or elevated testosterone or free androgen index (in the absence of late-onset congenital adrenal hyperplasia [14].

Agnucaston

Composition

Each film-coated tablet 120.5 mg contains: Active Ingredient Dry extract of the fruit of the chaste tree extract..........20 mg Excipients.

Povidone, lactose 1 H2O, magensium stearate, macrogol, tacl, ammonium methacrylate copolymer, titanium (IV) oxide (E171), yellow iron oxide (E172), indigone lacquer (E132).

1 film-coated tablet contains: 4.0 mg dry extract of chaste tree fruits (Special extract BNO 1095) (7-11:1); extracting agent: ethanol 70 % (v/v) other ingredients: Lactose-monohydrate 25.0 mg.

Pharmacological action

Pharmacological investigations suggest that aqueous alcoholic Agnus castus extracts exerts their effects via a dopaminergic principle of action thereby inhibiting prolactin release.

Bicyclic diterpenes have been shown to contribute to the dopaminergic effects of Agnus castus extract BNO 1095. These substances bind to the human dopamine receptor subtype 2 and dosedependently lower the prolactin release in cultured rat pituitary cells. Several clinical investigations show that administration of Agnus castus extract to women displaying latent hyperprolactinemia or increased prolactin resulted in a reduction of prolactin levels.

The prolactin-suppressive effect of Agnucaston has shown to be an effective treatment for PMS (premenstrual syndrome) and associated symptoms.

Indications

For the treatment of premenstrual syndrome and associated symptoms such as breast tenderness and mood changes.

Contra-indications

- In case of known allergy against chaste tree fruit or any other component of the medicine

- In case of pituitary tumors

- In case of mastocarcinoma.

Warnings

A regulation of the menstrual cycle also increases the probability of becoming pregnant. Patients with the rare hereditary galactose intolerance, lactase deficiency or glucose-galactose malabsorption should not take Agnucaston® Film-Coated Tablets.

Discussion

Polycystic ovaries are a common disorder in infertile patients .many drugs used for induction of ovulation in combination with clomiphen citrate in polycystic ovaries. There is currently no ideal medical PCOS therapy that fully reverses underlying hormonal disturbances and treats all clinical features. Metformin has had an increasing role in PCOS management, improving clinical features (ovulation, cycle regulation, and potentially hirsutism) with positive cardiometabolic effects. It does not appear to induce weight loss, although based on studies in DM2 it may assist in preventing future weight gain. In infertility, the role of metformin remains controversial. It does reduce hyperstimulation in those on other fertility therapies; however more research here is important. When using metformin it is better tolerated if started at 500 mg of slow release daily and increased over weeks to months to reach 2 g daily. Lactic acidosis is a rare side effect in those with other significant illnesses including renal impairment. It is important to note that neither metformin nor the OCP are approved by most regulatory authorities specifically for PCOS. About 30% of patients with polycystic ovaries have hyperprolactinemia therefore addition of anti hyperprolactinemic drugs in combination with clomiphen citrate may improve induction results and reduce also the miscarriage rate. Agnucaston (agnus castus) is an herbal compound with dopaminergic properties so reduce the level of prolactin and enhance the response of ovaries to stimulation by clomiphen citrate. The current work studied the effect of agnucaston in combination with clomiphen citrate in infertile patients with polycystic ovaries and the results showed that addition of agnucaston doubled the pregnancy rate when given with clomiphen citrate. This work gives a hope for infertile patients before ICSI procedure as a final resolution with cost benefit.
