It drops shortly after your period ends. You can see a fertility doctor to find out exactly when your eggs drop in your cycle.
Reproductive endocrinology and infertility (REI) is a surgical subspecialty of obstetrics and gynecology that trains physicians in reproductive medicine addressing hormonal functioning as it pertains to reproduction as well as the issue of infertility. While most REI specialists primarily focus on the treatment of infertility, reproductive endocrinologists are trained to also evaluate and treat hormonal dysfunctions in females and males outside of infertility. Reproductive endocrinologists have specialty training in obstetrics and gynecology (ob-gyn) before they undergo sub-specialty training (fellowship) in REI.
Reproductive surgery is a related specialty, where a physician in ob-gyn or urology further specializes to operate on anatomical disorders that affect fertility.
Human reproduction is any form of sexual reproduction resulting in the conception of a child, typically involving 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, which after a gestation period is followed by childbirth. The fertilization of the ovum may nowadays be achieved by artificial insemination methods, which do not involve sexual intercourse.
Menstrual cycle is the cycle of changes that occurs in the uterus and ovary for the purpose of sexual reproduction. It is essential for the production of eggs and for the preparation of the uterus for pregnancy. The menstrual cycle occurs only in fertile female humans and other female primates.
In humans, the length of a menstrual cycle varies greatly among women (ranging from 25 to 35 days), with 28 days designated as the average length. Each cycle can be divided into three phases based on events in the ovary (ovarian cycle) or in the uterus (uterine cycle). The ovarian cycle consists of the follicular phase, ovulation, and luteal phase whereas the uterine cycle is divided into menstruation, proliferative phase, and secretory phase. Both cycles are controlled by the endocrine system and the normal hormonal changes that occur can be interfered with using hormonal contraception to prevent reproduction.
Egg donation is the process by which a woman provides one or several (usually 10-15) eggs (ova, oocytes) for purposes of assisted reproduction or biomedical research. For assisted reproduction purposes, egg donation typically involves the process of in vitro fertilization as the eggs are fertilized in the laboratory; more rarely, unfertilized eggs are frozen and stored for later use by the intended parents. Egg donation is part of the process of third party reproduction as part of ART (Assisted Reproductive Technology). The ASRM (American Society of Reproductive Medicine) has issued guidelines for these procedures, and the FDA has a number of guidelines as well. There are boards in countries outside of the US who have the same regulations.
