Fertility Options

Hi there! My boyfriend and I have been talking about having kids in the future but he got a vasectomy when he was with his ex-wife about 4 years ago. As we spoke he said he didn’t want a reversal but was open to trying to have a child. I know there are multiple options for fertility treatment and was curious which ones are available and at what cost. I know the cost is specific to individuals but any treatment information or “average” cost information will be helpful. I wanna see how much I can plan ahead for this.

(By the way I’m 30 in Texas with no health or fertility issues to my knowledge)
