Do Mormons believe in the Virgin birth taught in the Bible? (LDS)

According to Brigham Young, the second prophet and president of the LDS church: > "The birth of the Savior was as natural as the births of > our children; it was the result of **natural action.** He partook of flesh > and blood--was begotten of his Father, as we were of our fathers." > > **(Journal of Discourses, vol. 8, p. 115).** > > "I have given you a few leading items upon this subject, but a great > deal more remains to be told. Now, remember from this time forth, and > for ever, that Jesus Christ was not begotten by the Holy Ghost." > **(Journal of Discourses, vol. 1, p. 51).** According to Orson Pratt the original member of the Quorum of Twelve Apostles of the Church of the Latter Day Saints: > The fleshly body of Jesus required a Mother as well as a Father. > Therefore, the Father and Mother of Jesus, according to the flesh, > must have been associated together in the capacity of Husband and > Wife; hence the Virgin Mary must have been, for the time being, the > lawful wife of God the Father: we use the term lawful Wife, because it > would be blasphemous in the highest degree to say that He overshadowed > her or begat the Savior unlawfully. > **(Orson Pratt, The Seer, page 158)** According to Luke 1:26-28: > 31 You will conceive and give birth to a son, and you are to call him Jesus. > 32 He will be great and will be called the Son of the Most High. The > Lord God will give him the throne of his father David, > > 33 and he will reign over Jacob’s descendants forever; his kingdom > will never end.” > > 34 “How will this be,” Mary asked the angel, “since I am a virgin?” > > 35 The angel answered, “The Holy Spirit will come on you, and the > power of the Most High will overshadow you. So the holy one to be born > will be called[a] the Son of God. > > 36 Even Elizabeth your relative is > going to have a child in her old age, and she who was said to be > unable to conceive is in her sixth month. 37 For no word from God will > ever fail.” Since Brigham Young says Jesus Christ was not begotten by the Holy Ghost and Orson Pratt says Jesus required a mother and a father, does that mean the Virgin Birth spoken about in the Bible is refuted from an LDS perspective?
