We are sorry to hear of your wife's situation. May she have a quick and complete recovery!
Both ejaculation outside of the vagina ("early withdrawal") and ejaculating into a condom are considered
hotza'at zera levatalah and are prohibited.
One possible method of birth control is the contraceptive sponge which may be less uncomfortable than the
diaphragm. It is at least as effective as a condom. You should also reconsider the
IUD. While there is a small risk for developing pelvic inflammatory disease from using an IUD (which may then increase the possibility of infertility), this is less of an issue with monogamous women. Please have your wife speak to her physician to discuss her concerns.
If it is critical to prevent pregnancy at this time, neither the condom nor
spermicide is very effective (75-85%). Therefore there is no particular advantage to condoms. However, if your wife is fully breastfeeding and has not yet resumed menstruation, due to the
reduction in fertility found in fully breastfeeding women, the level of protection spermicide offers may be sufficient.
Please read our article on
choosing a contraceptive method for more information and discuss all available options with her physician.
