Summary
Unexpected natural conception can occur in various scenarios during or after assisted reproductive technology (ART) treatments. Couples should be informed about these chances, ranging from 2-25%, to aid treatment decisions.
Area of Science:
- Reproductive Medicine
- Infertility Research
Background:
- Many couples pursue assisted reproductive technology (ART) after experiencing infertility or failed treatments like intrauterine insemination (IUI).
- Spontaneous conception following ART, successful or not, can be unexpected for couples.
Purpose of the Study:
- To review scenarios of spontaneous conception occurring around ART.
- To determine the likelihood of spontaneous conception in these scenarios.
Main Methods:
- Literature search on PubMed using terms 'spontaneous conception' and 'ART' or 'IVF'.
- Manual cross-referencing to ensure comprehensive literature retrieval.
Main Results:
- Spontaneous conceptions occur before ART initiation, between cycles, after ART failure, and after successful ART.
- Factors influencing spontaneous conception include waiting time, treatment gaps, cost, age, infertility duration, and cause.
- Chances range from 2% to 25%, with female age and male factor impacting rates.
Conclusions:
- Couples undergoing ART should be informed about the possibility of spontaneous conception.
- This information can guide decisions about starting, continuing, or discontinuing fertility treatments.

In Vitro Fertilization
In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

Infertility in Males
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...
Fertilization
During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...
