We are planning to conceive , im 29! we are trying ,sex without penetration, depositing seprm into vaginal opening . what are the chances to conceive?

Why? Prob won't work: You might conceive with ejaculation into the vaginal opening, but much more likely with penetration and ejaculation well inside the vagina. Even with normal intercourse and ejaculation high in the vagina, it usually takes several menstrual cycles before success. Why no penetration??

The basics: To conceive,a healthy sperm must enter your womb & travel to the Fallopian tubes at the proper time when a fertile egg is there.Not placing the sperm near the womb, not being on time, not having fertile sperm or egg will prevent success. The cited average wait for a desired pregnancy is 6 mo,range wks to a year or more. Regular sex gives you the best chance. What you are doing will hinder not help
