Due to the difficulty in collecting ejaculate produced during nocturnal emissions, relatively few studies have examined its composition. [4] [5]In the largest study, which included nocturnal emission samples from 10 men with idiopathic anejaculation, the semen concentration was equivalent to samples obtained from the same men by penile vibratory stimulation, although the proportions of sperm ...

For these women, the rhythm method formula incorrectly identifies a few fertile days as being in the infertile period. [19] Roughly 30-50% of women have phases outside this range. [34] Finally, calendar-based methods assume that all bleeding is true menstruation. However, mid-cycle or anovulatory bleeding can be caused by a number of factors. [35]
In case of amenorrhea, a period can be induced by intake of an oral progestin for 10 days. Daily administration of the ovulation induction regimen, starting on day 3, 4, or 5, [23] and it is usually taken for 5 days. [9] [24] Sexual intercourse or artificial insemination by the time of ovulation.
[46] [50] [51] [52] From Contraceptive Technology: [53] Post-ovulation methods (i.e., abstaining from intercourse from menstruation until after ovulation) have a method failure rate of 1% per year. The symptothermal method has a method failure rate of 2% per year. Cervical mucus–only methods have a method failure rate of 3% per year.
In particular, prostaglandins induce abdominal contractions that can cause pain and gastrointestinal symptoms. [8] [9] The use of certain types of birth control pills can prevent the symptoms of dysmenorrhea because they stop ovulation from occurring. Dysmenorrhea is associated with increased pain sensitivity and heavy menstrual bleeding. [10] [11]
Inhibition of ovulation through an action on the hypothalamic-pituitary-gonadal axis. For a low-dose formulation, this may occur inconsistently in ~50% of cycles. [32] Intermediate-dose formulations, such as the progestogen-only pill Cerazette (Desogestrel), much more consistently inhibit ovulation in 97–99% of cycles. [33]
Some men may have a short refractory period that lasts only a few minutes, while others might not feel interested in intimacy for several hours after climax. And while there are likely some ...
