Scared? No. From what I have heard, the sonogram is, at worst, uncomfortable. Usually it is used to look for varicocele.
In some cases, when sperm can not be found in the ejaculate, sperm cells can be extracted using techniques such as TEFNA and TESE, enabling the doctors to perform IVF with ICSI.
Good luck!
