“…10 For women desiring pregnancy, timing of intercourse to coincide with a woman's most fertile time can be facilitated by monitoring key fertility hormones, which can be conveniently performed in a home-based setting using urinary ovulation testing. 11 Tracking the luteinizing hormone (LH) surge in urine has been shown to be a highly reliable indicator of impending ovulation. [11][12][13] Ovulation typically occurs *24 hours after the onset of the LH surge and will not occur in its absence.…”

Background: Women trying to conceive are increasingly using fertility-tracking software applications to time intercourse. This study evaluated the difference in conception rates between women trying to conceive using an application-connected ovulation test system, which measures urinary luteinizing hormone and an estrogen metabolite, versus those trying without using ovulation testing. Materials and Methods: This home-based study involved 844 volunteers aged 18-40 years seeking to conceive. Volunteers randomized to the test arm were required to use the test system for the duration of the study while those randomized to the control arm were instructed not to use ovulation testing. Pregnancy rate differences across one and two cycles between the two groups were examined. Results: Volunteers in the test (n = 382) and control arms (n = 403) had similar baseline demographics. The proportion of women pregnant after one cycle was significantly greater in the test arm (25.4%) compared with the control arm (14.7%; p < 0.001). After two cycles, there continued to be a greater proportion of women pregnant in the test arm compared with the control arm (36.2% vs. 28.6%; p = 0.026). In the test arm, volunteers had intercourse less frequently per cycle compared with those not using ovulation testing (9 [range: 1-60] vs. 10 [range: 1-50]; p = 0.027), but were more likely to target intercourse to a particular part of their cycle compared with those not using ovulation testing (88.5% vs. 57.8%; p < 0.001).Conclusion: Using the test system to time intercourse within the fertile window increases the likelihood of conceiving within two menstrual cycles.

“…For women with cirrhosis in whom anovulation is suspected, serum progesterone may also provide useful information. Although no universally accepted cutoff exists, a progesterone level collected within the luteal phase of the menstrual cycle (usually on day 21) is suggestive of ovulation if it falls within the luteal phase reference range and/or exceeds 5 ng/mL . However, progesterone levels below the expected luteal phase range do not rule out ovulation, especially if the sample was not collected on day 21, which is often the case in women who are oligomenorrheic or amenorrheic.…”

Sexual Dysfunction and Sex Hormone Abnormalities in Patients With Cirrhosis: Review of Pathogenesis and Management

Healthy sexual function is important to maintain a good quality of life but is frequently impaired in patients with cirrhosis. The degree of sexual dysfunction appears to be linked with the degree of hepatic dysfunction. In men, sexual dysfunction can be related to the hyperestrogenism of portal hypertension and/or to decreased testosterone resulting from testicular dysfunction. In women, suppression of the hypothalamic–pituitary–gonadal axis appears to be a principal contributor, with no significant effect of portal hypertension. There is also a huge psychological barrier to break through as there is a component of depression in many patients with cirrhosis. Sexual dysfunction is often underdiagnosed in the cohort with cirrhosis. Management of sexual disorders in patients with cirrhosis can be challenging as they are often multifactorial. A multidisciplinary approach is key in managing these patients. We review the current literature on the pathogenesis of sexual dysfunction in patients with cirrhosis and propose a stepwise algorithm to better manage these patients.

“…Menstruation cycle is a naturally designed mechanism which affects female health and daily living quality for a span of approximately 35 to 40 years, from the beginning of adolescence to menopause [1]. Although the flow of blood during menstruation is the most noticeable event, the most important event is ovulation, which refers to the release of a mature egg from the ovary.…”

“…However, women generally have a menstrual cycle of 28 days [3,4]. Women understanding on menstrual cycle is beneficial for them to identify to detect fertile period rely on their ability to detect the fertility window, which begins approximately 3-5 days (sperm lifespan) before ovulation and continues to approximately 1-2 days (oocyte life span) after ovulation [1,5].…”

Detection and monitoring of ovulation has long been practiced by women, particularly those participating in a natural family planning program. The urge of Indonesian Government for the society to participate in family planning program has caused the increasing demand for cheap and efficient method of self-test to predict fertile period in each menstrual cycle. The cheap, easy, and efficient method in predicting fertile period would be beneficial in encouraging more people to participate in natural family planning program. There are several low-cost methods can be used to detect the time of ovulation as an indication of fertile period, such as basal body temperature and cervical mucus. However, their interpretation is not always easy, particularly for young women. Calendar system and salivary ferning are two methods which have been perceived easy to be implemented and do not require special expertise, yet has been effective in promoting natural family planning practice. Calendar system is a method which requires a woman to keep track of menstrual cycle length using a calendar. Salivary ferning is the formation of crystalsalivary ferning simultaneously may provide a better insight in fertile period based on calendar system and salivary ferning. The result of observation showed that salivary ferning pattern found on day 11 and 16 of a menstrual cycle which is included in fertile days based on calendar system. The formation of salivary ferning pattern during fertile period as calculated through the calendar system support the potential use of calendar system and salivary ferning simultaneously as a double check to detect fertile period.
