(The Torah States in Leviticus 1:2) Speak to the sons of Israel, When a person among you shall bring an offering to Hashem, he shall lean his hands on the head of the olah offering. This teaches that the sons of Israel perform Semichah (Personal Sacrificial offering, where the owner of the animal places both hands on the animal and leans on the animal while confessing) but the Daughters of Israel do not perform Semicha on their sacrifices.
R'Yose and R'Simon say: The daughters of Israel have the option to perform Semichah if they wish.
Abba Elazar recounted the following incident: One time we had a calf that was a Shelamim offering, and we brought it to the women's section of the courtyard (of the temple). The Women performed semichah on it. Not because there is a Semicha requirement for women, but in order to give satisfaction to the women.
[the Gemara in Rosh Hashanah 33a discusses the fact that women may perform the mitzvah of blowing the shofar. Once again in Gemara we see a source where women are permitted to perform time bound mitzvahs normally reserved for men. It's a well know fact that Rashi's daughters use to put on tefillin daily. Why are women not required to perform "time bound mitzvahs" (aside from lighting candles on shabbat)? The answer can be found in a misconception of orthodox Judaism. Many think that in orthodox Judaism, Women are treated as second class citizens.
THIS CAN'T BE FURTHER FROM THE TRUTH!
Men need to perform time bound mitzvahs to come closer to Hashem. This is because, through out the Torah there is incident after incident where MEN are going against the word of Hashem and sinning. The closest incident we find in the Torah where a woman has sinned is when Miriam spoke lashon horah (gossip) against her brother Moses. Men have to perform physical mitzvahs to make up for the sins of their forefather. Women don't have that issue. A woman's soul is closer to G-D then a man's soul. Women are spiritually superior then men. A women can do one thing (with the help of Hashem) that a man can never do, and that is give birth. It is these reasons that a women's soul is much loftier then a mans, and therefore is not required to perform time bound mitzvahs.
There are people who wear orange jump suits and pick up trash on the side of the road. They do this because they have to perform community service as part of their punishment. That doesn't stop someone from picking up trash if they were so inclined. But they don't HAVE to... Same hold true for Women and Mitzvahs.
How did that old Harry Belafonte song go? "That's right... The women are smarter... that's right, the women are... insert: Spiritually Superior" ]
