The odor, vision, touch and environment will play a role in initiation of this act. Male with erectile dysfunction will suffer with the failure to penetrate. The premature ejaculation may results with less pleasure or mental satisfaction.

Conception is fertilization. It is the fusion of sperm and ovum (egg) that produces a fertilized ovum (embryo). In human the fertilization usually occurs at the fallopian tube. This will occur in fertile period of the menstrual cycle. The sperm gives 23 chromosomes (paternal) and the ovum provides 23 chromosomes (maternal), these combination will gives 23 pairs of chromosomes.
Fertilized ovum will moves towards the uterus. The cell will divide in to two, then two cell produces four, then eight. The embryo should be implanted into the uterine cavity to produce a normal pregnancy.
By using contraception methods, the intercourse can be protected from conception. Even with an unprotected sex (not using any contraception) the chances of conception is less as the fertile period of human menstrual cycles are narrow compared with the menstrual cycle.
The couple fails to conceive naturally, can seek the doctor’s help for assisted conception or artificial conception.
