Effective public health programs, research, and policy relating to human sexuality, pregnancy, contraception, and the transmission of sexually transmitted infections depends upon knowledge of the structure (anatomy) and function (physiology) of the male and female reproductive systems.
Human reproduction is any form of sexual reproduction resulting in human fertilization. It typically involves sexual intercourse between a man and a woman. During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the woman's ovum by the man's sperm.

During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the woman's ovum by the man's sperm.
By the end of this section, you will be able to:
Describe human male and female reproductive anatomies
Describe spermatogenesis and oogenesis and discuss their differences and similarities
Describe the role of hormones in human reproduction
Describe the roles of male and female reproductive hormone
The reproductive events in humans include formation of gametes (gametogenesis), i.e., sperms in males and ovum in females, transfer of sperms into the female genital tract (insemination) and fusion of male and female gametes (fertilisation) leading to formation of zygote.
this is a long study on all aspects of human reproduction & most asked questions about human reproductive system ( medical information ).

An Overview of the Human Reproductive System: Integrating the slides sourced from similar topics on slide-share (I have fused different slides from slide-share: no information is originally researched)
Human reproduction is any form of sexual reproduction resulting in human fertilization. It typically involves sexual intercourse between a man and a woman. During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the woman's ovum by the man's sperm.
The reproductive tissues of male and female humans develop similarly in utero until about the seventh week of gestation when a low level of the hormone testosterone is released from the gonads of the developing male. Testosterone causes the primitive gonads to differentiate into male sexual organs. When testosterone is absent, the primitive gonads develop into ovaries. Tissues that produce a penis in males produce a clitoris in females. The tissue that will become the scrotum in a male becomes the labia in a female. Thus the male and female anatomies arise from a divergence in the development of what were once common embryonic structures.
