[165] Other adverse effects associated with CC are hot flashes, scotomas, dryness of the vagina, headache, and ovarian hyperstimulation, which, although rare, has been reported in patients who are sensitive to CC. [166, 167] Whether the use of CC increases the risk of ovarian cancer is unknown, although 2 articles illustrate a potential risk. [168] Other authorities disagree with this assumption.

Common symptoms of infertility include the following. When used in the early follicular phase, letrozole inhibits estrogen synthesis, thereby causing enhanced GnRH pulsatility and consequent FSH and inhibin stimulation. BMI (body mass index) may be a significant factor in fertility, as an increase in BMI in the male by as little as three units can be associated with infertility. Normal cervical mucus to allow passage of the sperm to the upper genital tract. Happily, many couples treated for infertility are able to have babies. A high serum estradiol level (greater than 60 to 80 pg per mL [220 to 294 pmol per L]) in conjunction with a normal FSH level has also been associated with lower pregnancy rates. As the major causes of infertility are sperm abnormalities, ovulation dysfunction, and fallopian tube obstruction, the preliminary adviced investigations for the infertile couple should be focused on semen analysis (to be compared with the WHO reference values [27]), detection of ovarian function by hormonal assay (early follicular FSH and LH levels, and mid-luteal progesterone), and evaluation of tubal patency by hysterosalpingography (HSG) [17-32], (Appendix 3). A decreased testosterone level with an increased FSH level points to primary hypogonadism. These numbers are comparable to those of other industrialized nations.
