In females most common problems are related to endometriosis, ovulation problems, poor egg quality, PCOS (polycystic ovarian syndrome) and female tube blockages, while in males the problem of infertility is referred to male tube blockages, sperm motility, quantity and quantity problems and sperm problems that relate to sperm allergy. There is also a possibility of unexplained infertility or combination infertility which accounts of 20-35% of all infertility problems.
In cases of endometriosis surgery can be applied: in that case 40-60% of women conceive in a period of a year and a half after the procedure. In vitro fertilization is also a method that is often applied and also has relatively high success rate. In cases of ovulation problems ovulation-stimulating drugs are used. These drugs include clomiphene, follicle-stimulating hormones, human chorionic gonadotrophin (HCG). In cases with problematic ovulation in vitro fertilization (IVF) can also be applied. Women that have problems with poor egg quality can be treated either with option of egg donation or surrogacy. The statistics are also encouraging since more than 40% of women who have received fertilized donor egg do become pregnant.
Women who suffer from PCOS (polycystic ovary symptom) can be treated with drugs that stimulate ovulation or with the help of in vitro fertilization. Women who suffer from tube blockages can undergo laparoscopic surgery to open tubes. Laparoscopic surgery is possible in cases of small area blockage, while there is still an option of in vitro fertilization.
