Ovulation induction with the antiestrogen clomiphene citrate, followed by follicle-stimulating hormone, is the standard treatment for norm gonadotropic an ovulatory infertility. Multiple follicle formation, which is linked to ovarian hyper stimulation and multiple pregnancies are the most serious side effects. Data on cumulative singleton and multiple pregnancy rates following various induction therapies is required. Insulin sensitising medications, aromatase inhibitors, and laparoscopic ovarian electrocoagulation are examples of newer ovulation induction techniques that should be compared to traditional treatments. If patient subgroups with different possibilities of success or difficulties with novel or traditional approaches could be identified using multivariate prediction models based on initial screening parameters, ovulation induction efficiency could improve. This would make ovulation induction more cost-efficient, safe, and convenient, allowing doctors to choose the most successful and patient-tailored therapy options.

Anovulation disorders cause about 30% of infertility and are characterised by irregular periods (Oligomenorrhoea) or the absence of menstruation (Amenorrhoea). Because many of the therapies are simple and effective, couples may only need to see doctors on a limited basis. In contrast to the stressful, more scientific setting of assisted conception, this makes it easier for a couple to preserve a private love relationship. However, ovulation induction is not effective for all causes of anovulation. Anovulation can occasionally be addressed by medicinal or surgical induction, although whether or not this is possible depends on the reason of the anovulation [1,2].

Causes are hypothalamic-pituitary. Hypo gonadotropic hypogonadism is defined by the pituitary gland's selective failure to generate FSH and LH. Excessive activity, being underweight, or both are the most typical causes. Because of a natural reduction in the hypothalamic production of gonadotropin releasing hormone, women with a low Body Mass Index (BMI), such as 18kg/m2, or who exercise extensively, such as gymnasts, marathon runners, and ballerinas, may develop amenorrhoea. When it comes to pregnancy, women who are underweight for their height are more likely to have. Small for dates infants, and children of women with eating disorders are more likely to be admitted to the hospital with failure to thrive. Sheehan's syndrome (Pan Hypopituitarism) and Kallman's syndrome (Amenorrhoea with anosmia caused by congenital lack of hypothalamic gonadotropin releasing hormone production) are uncommon. Children with a craniopharyngioma or some types of leukaemia may experience hypo gonadotropic hypogonadism as a result of brain irradiation, which can impact the hypothalamus or pituitary [3,4].

A pituitary micro adenoma is the most common cause of hyperprolactinemia. Pituitary FSH and LH production is reduced as a result of this. Although secondary amenorrhoea is the most prevalent symptom, some women may also experience galactorrhoea. A lesser percentage may experience headaches or blurred vision, which could suggest a macro adenoma that requires immediate diagnosis and treatment. A micro adenoma is easily treated with medications, resulting in the return of menstruation and fertility [5,6].

Ovarian disorders an ovulatory infertility is most commonly caused by polycystic ovary syndrome (70 percent). The fundamental anomaly appears to be an increase in androgen synthesis in the ovary, which results in the recruitment of a significant number of tiny preovulatory follicles that do not respond to normal follicle stimulating hormone concentrations. As a result, dominating follicles are uncommon. Women with polycystic ovarian syndrome often have hirsutism, acne, or irregular periods (cycle length > 35 days) in their late teens or early 20s. Even if they ovulate, these women have a lower likelihood of pregnancy since there are fewer ovulatory episodes in a particular time frame. Obesity affects women with the condition in varied degrees (30% to 70%) and is typically of the central type. Increased peripheral insulin resistance is directly connected to central obesity, which is a key hallmark of the so-called Metabolic Syndrome (IR). Furthermore, PCOS has been linked to an increased risk of insulin resistance, which is independent of obesity [7,8].

Age, BMI, hyper-androgenism, and insulin resistance were the most important determinants of treatment outcome. These predictors, on the other hand, are only applicable to the research population and may only be used clinically after being validated in several patient populations [9,10].

Although the results of the traditional ovulation induction protocol may be acceptable, with a cumulative singleton live birth rate as high as 71% before IVF61, new modalities in the classic treatment algorithm, such as insulin sensitizers, aromatase inhibitors, or laparoscopic electrocoagulation of the ovaries, may improve the outcome even more. Furthermore, the cost-effectiveness of various personalised treatment protocols should be considered, as it may help to improve the individualised ovulation induction treatment algorithm.
