There has been some research done on yoga postures, which suggest that specific poses can increase fertility.  Because yoga poses increase blood flow to certain organs, yoga may help to stimulate ovulation and make the uterus more conducive to conception. Additionally, it has been found that couples undergoing IVF treatment who are also practicing yoga regularly are more likely have successful results. For this reason, many fertility clinics have begun to offer yoga courses, along with other complimentary forms of treatment.
