Solution
The correct option is A Cessation of lactational amenorrhea period
After childbirth, a female experiences a period of intense lactation during which the menstrual cycle does not occur. No menstruation means no ovulation. This temporary period of intense lactation and stoppage of the menstrual cycle after childbirth is called lactational amenorrhea. This happens because the hormone prolactin which induces breast milk production plays an active role in preventing fertility by inhibiting follicle-stimulating hormone (FSH) and gonadotropin-releasing hormone (GnRH), the hormones that trigger ovulation and allow eggs to develop and mature. However, this effect of being infertile is temporary in nature, varies between women and is generally observed to last a period of six months only. Coitus should not be engaged in without using contraceptives as false sterility might lead to conception. This is what would have happened to the couple with an 8- month old baby who indulged in sexual activity.
For successful fertilisation to occur, the sexual act should occur during the period of ovulation because the secondary oocyte remains alive for 1-2 days after ovulation. A sexual act that occurs a week after ovulation may not lead to successful fertilisation in most cases.
The bleeding phase of the menstrual cycle is the phase during which the cells of the endometrium, blood and the unfertilised ovum are expelled out from the female's body as menstrual blood. During this particular period, fertilisation cannot occur as the ovum is lost
In general, an increase in copper ion concentration leads to suppression of sperm motility and fertilising capacity of the sperms.
